Extremely Slow performance with X58 Platinum

I just upgraded from a core 2 quad 6600 with 8 gb of ram
to a core i7 920 on an X58 Platinum with 12 gb of 1333 ram (yes the ram is an approved spec according to the MSI online manual....I checked the part numbers on the ram)
I have an 9800gx2 and a velociraptor for a system drive, I have all the latest windows updates(vista 64) and the new 1.1 bios revision...and all the graphic card updates and chipset updates from intel
It is running so slow that as I type this the letters on screen cannnot keep up with my fingers, and I am not that fast of a typer.
It fells like I went back in time to a p3 or something.
Where should I begin to diagnose the problem??
Thanks in advance

I too have stepped back in time with my x
MSI x58 platinum board
Specs
Motherboard Name MSI X58 Platinum SLI (MS-7522)Bios 322
3 GIG Ram Aeneon AXH760UD10-16HA08X
CPU Type QuadCore Intel Core i7 920, 3800 MHz (21 x 181)
CPU Cooler Noctua NH-U12P SE1366 LGA1366 i7 Heatpipe Cooler W/ 2XNH-P12 120MM Fan
Hard Drives Raptors SATA Stripe (297 GB)Raid 0
Video nVIDIA GeForce GTX 285 SLI
OS Microsoft Windows Vista Ultimate(64 Bit)
I am running Raid 0 and performance is just terrible.Overclocks like a champ but the board is pretty much useless when it runs slow.
Things I have tried installed BIOS 322 which brang boot time to desktop to 1 minute 45 secs slow but ok I guess,some improvement in a couple games.
Installed XP64 no help or performance gain.
Windows 7 would just not install any drivers at all.
Vista 64 8 installs with no performance with different drivers.(You can install drivers off usb stick)
Bought a new Motherboard but I am going to wait a few days more and see if others BIOS will help.
There seems to be a few new BIOS I will try some them out today.
Contacted MSI tech support and they were kind enough to suggest the bios,you can give that a shot and see if it helps you out.My board is Platinum SLI board but should be same as Platinum board also but they have all the platinum BIos there too.
Regarding your concern,please log into following link to download and update to the latest bios A7522IMS.322:
-ftp link, username, password removed--not for public release
We would suggest you try to update the BIOS by using USB Bootable pendrive.It is convenienct for you:
1.First of all,please make a bootable USB.You can download USBoot.rar from following link.Then please unzip this software and install it to make a booting USB device:
--ftp link, username, password removed--not for public release
2.Next go to our website to download BIOS file, then copy “AFUD4281.exe” and “A7522IMS.322” into USB.
3.After that, restart PC, press F11, choose USB booting under “boot sequence”.
4.Under DOS mode, please type “AFUD4281.exe A7522IMS.322”(without the quotation marks)and it will be updated successfully!!
Remember to clean CMOS and Load Optimized Defaults under bios setup after you finish the BIOS update!

Extremely slow performance with Radeon HD 7870

Hi,
I am using a number of Adobe programs on my new Windows 8 64 bit system, with 16 gigs of ram, an Intel Core i5 2.67ghz, and AMD Radeon HD 7870 2 gig. All the programs (including After Effects and Illustrator) work very well with the exception of Photoshop CS6 64 bit, which has extremely slow performance with Use Graphics Processor enabled in my preferences (which Photoshop selects by default). If I turn off Use Graphics Processor, the slow performance vanishes. If I change Drawing Mode to Basic, there might be a slightly detectable improvement over Normal and Advanced, but it's still horribly slow. The refresh rate seems to be just a few frames per second. Everything is slow: brushes, zooming, panning, everything.
I've tried changing the settings I've seen suggested elsewhere: I switched Cache levels to 2, history states to 10, and tile size to 128k. No effect. Photoshop is currently at the default of using 60% of available ram. Efficiency has remained at 100% throughout all my tests. Also, this slow performance has affected me from the moment I installed Photoshop; it didn't crop up after previous good performance. The problem exists regardless of the size or number of documents I have open. Performance is still terrible even when I create a 500 x 500 pixel blank new canvas and try a simple task like drawing with the brush.
Photoshop is fully up to date, and so are my graphics drivers (Catalyst version 13.1). Any help would be greatly appreciated; at the moment performance is so bad in Photoshop that it's unusable with graphics acceleration enabled. Thanks in advance for replying.

Great news!
I followed your suggestion, Noel, and uninstalled my drivers with the Catalyst Uninstall Utility (which I hadn't used before), rebooted, reinstalled Catalyst 13.2 Beta 7, rebooted, deleted the PS Prefs, started PS, and now the performance is radically improved!
It baffles me why I would need to do a clean driver uninstall in a new system environment that has only ever had this video card, and is only a few months old, but that action seems to be what's improved the situation. Note that because I deleted the PS preferences, the good performance now occurs with the default Use Graphics Processor enabled, and Drawing Mode set to Advanced (with every feature in the Advanced dialog checked except 30bit display).
Having no reference point, I can't tell for sure if performance is as good as it theoretically ought to be for my system specs, but using the standard 13px brush is only slightly laggy behind the cursor, even if I become reckless and squiggle on the canvas violently. It wasn't just sluggish response before: Photoshop seemed to be in pain trying to draw the line segments as it laboured to catch up to the cursor. That is pretty much gone now.
Much more tellingly, zooming and panning the canvas is like it ought to be, responsive and clean, more or less like it was for me in CS4 with my old Nvidia 9600GT. The poor performance with zooming and panning was the most worrying aspect of the issue. It's a great relief to see these working more properly now.
I have to confess I'm a little embarrassed to have drug you through all this hassle only to discover that something as rudimentary as properly cleaning out the drivers would be the apparent solution. I never would have imagined that doing that, with such a new and stable system, would make any difference, since I don't have a legacy of older drivers dotting my hard drive. In any event, I'm really grateful that you guys took the time to try to help me.
In the interest of completeness, here's the relevant portion of my system info after doing the reinstall steps I mentioned above:

As you can see, the Microsoft Basic Render Driver still appears as a Video Card in the list. This presumably has something to do with Windows 8, and I really don't know if its presence here is still a sign that my card is not being used to its optimal capability. I have a hunch that the slight lag that I am still experiencing with the brush when Use Graphics Processor is on -- totally absent with the acceleration turned off -- implies that Photoshop is still unable to take maximum advantage of my card. I would assume that the brush tool should be more responsive with acceleration on than off, in a rig without any issues, but that's just assumption on my part. If you turn off Use Graphics Processor on your systems, is the brush tool more or less responsive?
But again, panning the canvas with the hand tool is now extremely responsive, without any screen tearing or visible lag, and that's a massive improvement over the total meltdown of performance I was suffering from before.
Thanks again very much for your help. I'm grateful to all of you who took the time to chime in.

Extremely slow performance with ojdbc6.jar on IBM JVMs (Java 6)

We are consistently seeing slow performance (easily demonstrable by the simplest of test cases) while using ojdbc6.jar on IBM JDKs. Pefrormance is normal when we simply opt for ojdbc14.jar under the same JDK, same java program.
Works well
=======
JRockit, ojdbc6.jar
JRockit, ojdbc14.jar
IBM JDK, ojdbc14.jar
A lot slower
=======
IBM JDK, ojdbc6.jar
All we had to do was to write a simple JDBC access program and measure time taken around
Connection conn = DriverManager.getConnection(jdbcURL, dbProps);
The first 3 combinations mentioned above return comparable numbers. The 4th combination takes 3-4 times as much.
We initially saw this during performance test of our software on WebSphere (also supported on Weblogic). Later was able to eliminate WebSphere and Weblogic as the problem areas and narrow it down to the JVM. Reproduce-able on development machines.
We have been using Oracle/WLS since BEA used to market 'Tengah' servers. This is the worst we have seen as far as the qaulity of support staff goes. We first level support seems clueless. We filed this case and the support comes back tells us that IBM JDKs are not supported for WLS! Oh, we have been running WLS/AIX/IBM JVM combination only for 5+ years.

A quick solution to test this would be to do the following:
mv /dev/random /dev/random.bk
ln /dev/urandom /dev/random
Note: The quick solution will disappear after a reboot. You could add it to rc.local to automatically make this change, but I wouldn't recommend it.
The following is from [http://www.usn-it.de/index.php/2009/02/20/oracle-11g-jdbc-driver-hangs-blocked-by-devrandom-entropy-pool-empty/]:
"Oracle 11g JDBC driver hangs blocked by /dev/random – entropy pool empty
On a headless (=without console) network server, the 11g JDBC driver used for (java) application connect may cause trouble. In my case, it refused to connect to the DB without any error, trace or log entry. It simply hung. After several hours, it connected one time, and freezed again. Remote debugging done by the development clarified that it locks after calling SeedGenerator() and SecureRandom().
Reason: The JDBC 11g needs about 40 bytes of secure random numbers, gathered from /dev/random, to encrypt its connect string.
But public-available “man 4 random” says:
When read, the /dev/random device will only return random bytes within the estimated number of bits of noise in the entropy pool. /dev/random should be suitable for uses that need very high quality randomness such as one-time pad or key generation. When the entropy pool is empty, reads from /dev/random will block until additional environmental noise is gathered.
So far so good, now the question arises: Why does this mystic “entropy pool” runs out of gas?
The answer is as simple as unsatisfying: because too less entropy “noise” was generated by the system. You can check the “filling level” (maybe zero?) of your pool and the overall size of the pool (usually 4096) by issuing
cat /proc/sys/kernel/random/entropy_avail
cat /proc/sys/kernel/random/poolsize
Hint: /dev/random will deliver one new random number as soon as the pool has reached more than 64 entropy units.
So why does my box not generate more entropy noise?
Because only few drivers will fill the entropy pool, first of all keyboard and mouse. Sounds very useful on a server in a datacenter, isn’t it? Some block device and network drivers seem to do so as well, and I have read from guys on the net changing their network card and driver to enjoy this “feature”! But let’s stop ranting, /dev/random is simply made for high security randomness, and if it can’t make sure that randomness is as good as possible in this deterministic world, it stops. Intelligent people have created /dev/urandom for that, like “man 4 random” clearly states:
A read from the /dev/urandom device will not block waiting for more entropy. As a result, if there is not sufficient entropy in the entropy pool, the returned values are theoretically vulnerable to a cryptographic attack on the algorithms used by the driver. Knowledge of how to do this is not available in the current non-classified literature, but it is theoretically possible that such an attack may exist. If this is a concern in your application, use /dev/random instead.
Now let’s get back on our JDBC problem. Oracle JDBC 11g seems to use /dev/random by default, which causes usually no trouble on clients running with console access by a user, because his/her unpredictable :) actions will keep the entropy pool well-fed. But to make it usable on a headless server with a latently empty entropy pool, you should do several things, in descending security order (without warranty):
1. Involve an audio entroy daemon like AED to gather noise from your datacenter with an open microphone, maybe combine it with a webcam noise collector like VED. Other sources are talking about “Cryptographic Randomness from Air Turbulence in Disk devices“. :)
2. Use the Entropy Gathering Daemon to collect weaker entropy from randomness of userspace programs.
3. Talk your JDBC into using /dev/urandom instead:
-Djava.security.egd=file:///dev/urandom"

Extremely slow performance with NEW hdd

Ok guys, this is pretty frustrating. Today I bought 2 new external hdd's, same manufacturer, same model. One of them seems to work great, but the other one.. well look at this:
/dev/sdk1:
Timing buffered disk reads: 96 MB in 3.04 seconds = 31.53 MB/sec
bash-3.2# hdparm -t /dev/sdj1
/dev/sdj1:
Timing buffered disk reads: 4 MB in 4.30 seconds = 951.52 kB/sec
As you can see, my sdj is extremely slow - what could possibly be wrong here?

Extremely slow performance with SR5105 Lockins in LabView 7.1

Hello,
I currently have an application which I've created for controlling a device used in cervical cancer diagnosis. This software has various controls ranging from controlling filter wheels with stepper motors, video capture, lockin data analysis and other various functions.
Everything is working well except the update rate at which I'm receiving results from my 2 Signal Recovery (SR) model 5105 lockins.
SR has provided labview drivers and even a starting interface which works perfectly under normal conditions. However I'm running 2 lockins concurrently and I'm getting very laggy results.
When I run the lockin vi from SR, the update rate is about once every .25 seconds or at least twice a second. When I put the same code into my application the update rate becomes very slow, ranging from once every 3 to once every 6 seconds. I've read the forums thoroughly as well as contacted an NI tech engineer but couldn't resolve this problem. I've heard that there might be a way to change execution settings in labview which would speed this up or perhaps I'm just doing something wrong (I'm pretty new at labview, about a year experience).
I'm including the code that I have. Unfortunately it won't run on your machine because it needs to be connected to proper hardware.
Pretty much I have about 5-6 parallel loops and at the very top you can see two identical copies of the lockin code. What can I do to improve performance? Thanks in advance.

Thanks for your reply. I have actually found a way to fix the problem and it had nothing to do with the subvi's in my application (well almost nothing . The first thing I tried doing was taking out the display local variables which displayed lockin data on 3 screens of my application into 1 separate while loop and replacing the Lockin driver code with global variables which had only the data I wanted to display. This helped a little bit but here's what fixed my problem completely.
When I created 2 lockin SubVIs I forgot to go into File->VI Properties->Execution and there select Time critical priority and in the other option drop down list: data acquisition.
As soon as I did that in the 2 subvi's the lockins actually began performing in real time and now it takes milliseconds to detect the signal and to update the displays.
I hope this helps. I'm surprised the NI Tech rep I spoke with, hasn't recommended this even though I asked if there are perhaps some sort of compiling or priority options in LabView.
Well I'm happy since my problem is now fixed, I just need to get a little more RAM now.

Airport Express and USB Hard drive and extremely slow performance

HI Guys,
I seem to having a lot of trouble with an Airport express and a Lacie 1TB drive. While I have solved several problems by updating firmware and enabling journalling on the Lacie, I am still having problems with extremely slow performance with my macbook, particularly using itunes and Firefox.
Any ideas and any further information needed?
Regards

not if you move them to a temporary location before you start.
yes, you are better of formatting the drive with DU.

Extremely slow performance on projects under version control using RoboHelp 11, PushOk, Tortoise SVN repository

We are also experiencing extremely slow performance for RoboHelp projects under version control. We are using RoboHelp 11, PushOk and a Tortoise SVN repository on a Linux server. We are using a Linux server on our IT guys advice because we found SVN version control under Windows was unstable.
When placing a Robohelp project under version control, and yes the project is on my local machine, it can take up to two hours to complete. We are using the RoboHelp sample projects to test.
We have tried to put the project under version control from Robohelp, and also tried first putting the project under version control from Tortoise SVN, and then trying to open the project from version control in Robohelp. In both cases, the project takes a ridiculous amount of time to open. The Robohelp status bar displays Querying Version Control Status for about an hour before it starts to download from the repository, which then takes more than an hour to complete. In many cases Robohelp becomes unresponsive and we have to start the whole process again.
If adding the project to source control completes successfully, and the the project is opened from version control, performing any function also takes a very long time, such as creating a topic. When I generated a printed documentation layout it took an astonishing 218 minutes and 17 seconds to complete. Interestingly, when I generated the printed documentation layout again, it took 1 min and 34 seconds. However when I closed the project, opened from version control, and tried to generate a printed documentation layout, it again took several hours to complete. The IT guys are at a loss, and say it is not a network issue and I am starting to agree that this is a RoboHelp issue.
I see there are a few other discussions here related to this kind of poor performance, none of which seem to been answered satisfactorily. For example:
Why does it take so long when adding a new topic in RH10 with PushOK SVN
Does anybody have any ideas on what we can do or what we can investigate? I know that there are options for version control, but am reluctant to pursue them until I am satisfied that our current issues cannot be resolved.
Thanks Mark

Do other applications work fine with the source control repository? The reason I'm asking is because you must first rule out that there are external factors causing this behaviour. It seems that your it guys have already looked at it, but it's better to be safe than sorry.
I have used both VSS and TFS and I haven't encountered such a performance issue. I would suggest filing it as a bug if you rule out that the problem is not related to external influences: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform&loc=en

My macbook is experiencing an extremely slow performance. Everytime I try to do something, the screen will freeze and the pinwheel symbol would appear. How do I pix this?

My macbook is experiencing an extremely slow performance. Everytime i try to do something, the pinwheel symbol will pop up. I do not have an antivirus software until recently, which I got free from school and it said my mac has a virus, which has been quaratined. Unfortunately the problem still persist. Help?

kasturi pryanka,
your current slow performance might have been caused by installing that antivirus software. Have you tried disabling it, to see if that make a difference with its performance?

Slow Performance with Business Rules

Hello,
Has anyone ever had slow performance with business rules? For example, I attached a calc script to a form and it ran for 20 seconds. I made an exact replica of the calc script in a business rules and it took 30 seconds to run. Also, when creating / modifying business rules in EAS it takes a long time to open or save or attach security - any ideas on things to improve this performance?
Thanks!

If you are having issues with performance of assigning access then I am sure there was patch available, it was either a HSS patch or planning patch.
Cheers

Extremely slow performance transferring data over USB with Time Capsule

I have the 2TB wireless Time Capsule. I have it setup as an extension to my current WiFi at home, since I already had a WLAN router. I have an external harddrive (500gig) that I connected to my Time Capsule because I wanted to transfer data from the Time Capsule to the external HD. The external HD is formatted with FAT32 file system, so read/write is no problem.
When, using my MacBook Pro, I navigated to the Time Capsule and dragged files over to the connected USB harddrive (connected directly in the Time Capsule), the performance to transfer is extremely SLOW! It was slower than doing the transfer completely wirelessly (USB drive connected to laptop and transfer wirelessly from TC)!
I do not understand this at all! It should be a simple transfer using the USB connection! When I do a transfer from my laptop directly to the USB harddrive, with it connected directly to the laptop, the transfers are super fast!
What happened? Can someone please explain this or tell me what I need to do?
Thank you!

I am still confused here.
My original question was regarding the use of my USB external harddrive. It was connected to the back of the TC. The TC was wirelessly speaking to my WLAN router. Using my laptop (also wirelessly speaking to WLAN router), I navigated to the TC and saw 2 listings - one for the data on the harddrive in the TC and one for the new external USB drive connected to the back of the TC. I wanted to transfer data from the harddrive in the TC to the USB external drive. Based on what I expected, I thought the transfer rate would merely be limited by the USB 2.0 interface that is being used by the external drive. However, I was definitely wrong! The transfer rate (shown by the estimate in time to transfer the data by my MacBook Pro) was doubled to 14 hrs.
Originally, it was only 7 hrs when the USB external drive is connected directly to my laptop and I connect to the TC wirelessly. Weird!
So why doesn't the TC simply transfer the data from its internal harddrive to the external USB drive directly without using any wireless technology?
The second question I have is regarding the setup of the TC itself. I have a NetGear WLAN router and its an "n" router. So the speed is good. I have my TC currently downstairs from the WLAN router. Therefore the TC is setup as simply a wireless harddrive. It speaks through the WLAN router in order to be available to all my laptops in my house. My question is whether it should instead be directly connected to the WLAN router using an ethernet cable? Would this improve my overall transfer rates to/from the TC?
Thanks so much.

Slow performance with yellow highlight tool

Overclocking a Core i7 920 with X58 Platinum: Advice needed!

Hello everyone,
Just got my Core i7 920 and I would like to see how far I can take it with the hardware that I have. Although I've read countless overclocking articles over the years (mainly on Tom's Hardware), this is actually going to be my first time doing it. So I guess this makes me a n00b....
So, here is my hardware setup:
CM Storm Scout Case
Intel Core i7 920
MSI X58 Platinum
Coolit Systems Domino CPU Water Cooling System
G.SKILL 6GB DDR3-1600 CL 9-9-9-24
ASUS GeForce 9500GT Top
Seagate Barracuda 7200.12 1TB
PC Power & Cooling Silencer 750 Quad 750W
I've already tried fiddling around the BIOS and also tried the DIP switches on the MOBO (tried the 166 settings). At this point I'm guessing I'll have to turn off some options in the BIOS or something because CPU-Z is reporting different Core Speed, multiplier and QPI Link every 2 second.
For the record, I'm not necessarily trying to break 4Ghz with this overclock... just wanna take advantage of this 920 and the CoolIt Domino; anything stable between 3.2 and 3.8GHz and I'm happy

Depends on the type of blue screen you get.
The way I under stand it is if the errors end with 124 ie 0x0000124 this is most likely QPI related.
This is taken from the evga forums and I am only posting as a reference.. The Credit belongs to Freemortal at evga. Not everythign applies to the MSI boards but the important ones do.
This guide is an attempt to assemble as much info about the various i7 voltages you can change in the BIOS. I can't do it alone though. This community has a wealth of information on the subject. Please post what you know and I'll add it to the first post here. Please make it as concise as possible.
If you believe any of this information to be inaccurate, let me know.
NOTE: This guide is applies specifically to the "EVGA X58 SLI" motherboard released in 2008. Most of this info also applies to other X58 motherboards as well but some labels and tolerances may be different depending on the make. This guide assumes you use a high quality, after-market heatsink and fan. Do not raise voltages with the stock cooler!
THE VOLTAGES
Caution: The voltage you set is not necessarily the voltage you get. Furthermore the voltage you read is not necessarily accurate either. The Eleet utility (along with any other software monitoring utility) will simply report what the motherboard tells it to report. When measured independently, these readings are close, but not entirely accurate.
VCore (default: 1.28125v, Intel's max 1.375v, VCore over 1.50v on air cooling is risky)
What it does:
Sets max voltage to the CPU cores. (if Vdroop is disabled, it will set the min voltage instead) The i7 doesn't need much voltage at speeds under 3.8ghz. (For example, I can get 3.8ghz on 1.275 vcore) Beyond that the voltage requirements climb sharply.
When to raise VCore:
* BSOD 101 "Clock Interrupt not received from Secondary Processor"
* LinX produces errors that are very
* LinX errors happen within 1 min of LinX
* LinX produces BSOD within the first minute
You know VCore is too high when:
* CPU cores approach a peak of 85c on full load
* It is unknown how higher voltages may impact the life of the CPU
CPU VTT Voltage (default: 1.1V (+0mV in BIOS) Intel's max 1.35 (+250mV)
What it does:
VTT connects the cores with the memory. Raising VTT helps keep a system stable at higher QPI rate. Since QPI is calculated from bclk: the higher the bclk the more VTT voltage you will need. VTT is also called "QPI/DRAM Core" on other motherboards,
Prevent CPU damage: VTT voltage must be within 0.5V of VDimm. Vdimm can fluctuate by as much as 0.05V from settings so you may want VTT within 0.45V of VDimm for that extra margin of safety. Example: if Vdimm is 1.65V, then VTT must be at least 1.20V.
When to raise CPU VTT Voltage:
* BSOD 124 "general hardware failure"
* LinX errors happen only after 10 min or more
* LinX hangs but does not BSOD
* LinX reboots without BSOD
You know CPU VTT Voltage is too high when:
* Most users try and stay below 1.45V (+350V) for 24/7 use without additional direct cooling.
* The motherboard doesn't read the temp so you may need an IR thermometer to be sure you are not pushing VTT too far.
CPU PLL VCore (default: 1.800V, spec range: 1.65V-1.89V)
What it does:
Keeps CPU clock in-sync with bclk.
When to raise CPU PLL VCore:
* May help with stability while increasing the bclk or CPU multiplier.(or may make it worse)
* May help with stability past 210 bclk if you observe that during runtime the QPI Link (found in E-Leet) bounces too much.
* Not a commonly raised. May actually cause instability. Test this variable alone.
You know CPU PLL VCore s too high when:
* Its possible you could actually gain stability by lowering this.
DIMM Voltage (default: 1.5V, Intel's max 1.65)
What it does:
Voltage to the RAM. Despite Intel's warnings, you can raise voltage beyond 1.65 as long as it is always within 0.5V of VTT (as described above).
When to raise DIMM Voltage :
* High performance/gaming RAM usually requires at least 1.65v to run at spec. Some manage to get it slightly lower.
* Stable bclks over 180 often require VDIMM beyond 1.65V. Remember to keep VTT voltage within 0.5V of VDIMM.
You know DIMM Voltage is too high when:
* Memory is too hot. [more info on this is needed]
DIMM DQ Vref (default: +0mV)
What it does:
It is the reference voltage for a pseudo-differential transmission line. The DQ signals sent by the memory controller on the i7 should swing between logic-hi and logic-lo voltages centered around VREF. VREF is typically half way between the drain and source voltages on the RAM. Most VREF generator circuits are designed to center between the VDD and VSS voltages on the RAM. There is usually temperature compensation built into the circuitry as well.
When to raise DIMM DQ Vref:
* Vref might be adjusted if (after measurement) it was determined not to be properly centered between VDD and VSS of the DIMM. Without a good osciloscope it's difficult to imagine that most users could set VREF correctly. They may be able to set VREF empirically by moving it up or down and checking for POST or BSOD problems.
Further reading:
http://download.micron.com/pdf/technotes/ddr2/TN4723.pdf The document is for DDR2 but differential signaling is a topic that transcends memory models. It has been done for decades in high-end systems and the advantages/drawbacks are well understood.
QPI PLL VCore (default: 1.1v, <1.4v is pretty safe)
What it does:
Keeps on-chip memory controller in-sync with bclk.
When to raise QPI PLL VCore:
* Try raising this along with Vcore and VTT, but in smaller increments.
* Helps stabilize higher CPU Uncore frequencies and QPI frequencies (in CPU feature)
* Try raising this when you increase memory clock speed via multiplier.
* Try raising when LinX produces errors after a few minutes without BSOD
IOH Vcore (default: 1.1V)
What it does:
Sets voltage for on-chip north bridge which connects PCIE2.0, GPU, Memory, and CPU.
When to raise IOH VCore:
* Possibly needed if you overclock your north bridge (via bclk and CPU Uncore freq.)
You know IOH VCore is too high when:
* Memory errors? (just a guess)
* GPU intensive apps like 3dmark vantage crash. (another guess)
IOH/ICH I/O Voltage (default: 1.5V)
What it does:
some sort of on-chip bus voltage. unknown
ICH Vcore (default: 1.05V)
What it does:
South Bridge chip on the motherboard. Connects all motherboard features, cards (not PCIE2.0), and drives to CPU/memory on IOH
When to raise ICH Vcore:
* I don't know if raising this can help in overclocking at all. Possibly necessary in order to keep up with an overclocked northbridge?
You know ICH Vcore is too high when:
* unknown. I wouldn't overvolt it too much though.
PWM Frequency (default: 800)
What it does:
unknown
When to raise PWM Frequency:
* Overclocking beyond 4.2ghz
You know PWM Frequency is too high when:
* VREG approaches 85c
VDroop (default: enabled)
What it does:
Safety feature designed by Intel to protect the chip from excessive wear from voltage spikes. Enabling VDroop keeps actual voltage running below the VCore setting in BIOS
What does disabling VDroop do?
* Makes VCore setting the minimum value for actual voltage; CPU will run at higher voltages than what you set in BIOS.
* Disabling VDroop is the same as enabling Load Line Calibration on other x58 boards.
Why would I want to disable VDroop?
* Some overclockers use it because it allows them to get a high overclock while setting lower VCore in BIOS. This is because the running voltage is actually higher than what was set in BIOS. Disabling VDroop keeps actual voltage higher than what is set for VCore in the BIOS. Enabling Vdroop keeps actual voltage lower than VCore.
* It might help if you are pushing the bleeding edge.
Diagnosing errors. What to do when...
BSODs
* BSOD "IRQL_NOT_LESS_THAN_OR_EQUAL" (I forget)
* BSOD 101 "Clock Interrupt not received from Secondary Processor" Try raising VCore
* BSOD 124 "general hardware failure" Try raising VTT
LinX Errors
If you get an error you would have x same (correct) results and 1 different (an error):
* If the incorrect result differs slightly from the rest (numbers very close, same powers in Residual & Residual (norm)) it is most likely that there's not enough vcore. In this case only a small vcore bump is usually needed to stabilize the system (alternatively, Vtt & GTL tweaking can sometimes fix this too)
* If the wrong result differs much from the others (different power or even positive power in Residual or Residual (norm)) it might be 1) insufficient vcore (the error would happen at the very first runs then) or 2) some memory / NB instability (when it worked for say 10 minutes ok and then produced a different result)
More serious LinX errors:
* BSOD during testing (at the very first runs) is often caused by too low vcore
* System hangs and remains hung it is almost 100% not a CPU but memory or possibly NB issue
* System reboots (with no hang prior to reboot and no BSOD) - a CPU issue, but not vcore related (insufficient PLL or Vtt I guess)
* System hangs for a short while and then BSODs - once again NB or memory problem (but might be wrong Vtt / GTL setting as well)
* System hangs and then just reboots - wrong Vtt (too low or too high) or GTL settings

Slow Performance with large library (PC)

I've been reading many posts about slow performance but didn't see anything addressing this issue:
I have some 40000 photos in my catalog and despite generating previews for a group of directories, LR still is very slow in scrolling through the pics in these directories.
When I take 2000 of these pics and import them into a new catalog - again generating previews, the scroll through the pics happens much much faster.
So is there some upper limit of recommended catalog size for acceptable performance?
Do I need to split my pics up by year? Seems counter productive, but the only way to see the pics at an acceptable speed.

I also have serious performance issues, and i don´t even have a large database catalog, only around 2.000 pictures, the db file itself is only 75 mb big. Done optimization - didn´t help. What i encountered is that the cpu usage of LR 1.1 goes up and STAYS up around 85% for 4-5 minutes after programm start - during that time, zooming in to an image can take 2-3 minutes! After 4-5 minutes, cpu usage drops to 0%, the background task (whatever LR does during that time!) has finished and i can work very smoothly. preview generation cannot be the problem, since it also happens when i´m working in a folder that already has all previews build, close LR, and start again instantly. LR loads and AGAIN i´ll have to wait 4-5 minutes untill cpu ussage has dropped so i can continue working with my images smoothly.
This is very annoying! I will stop using LR and go back to bridge/acr/ps, this is MUCH much faster. BUMMER!

Sudden extreme slow performance

I have run Tiger on this machine for about 6 months with no problems. In the last few weeks everything has started slowing down noticably. The hard disk is running ragged, constantly reading/writing, from looking at the cpu monitor it seems like the computer is not actually using it's ram and is just reading and writing. I tried clearing caches and that worked for a few hours but the machine now seems to lock up after a few hours use. I get to the point where i cannot open menus, switch programs, or even force quit or restart. Everything locks up - spinning beachball - and the hard disk is left constantly writing. I have 9 -15Gb free out of 40Gb on the disk - i assume this is enough. Playing music and safari is no problem. But I am using iphoto and photoshop as well as other programs in the background. This was never previously a problem and ran smoothly. I know it's fairly vague but if anyone can help..

Hi, Ben.
Thanks. However, it would help to see some of the specific data points from the instructions in those FAQs. Specifically:
1. You wrote: "(the pageins/outs are about equal) but i'm getting REALLY slow performance across the board. "It still sounds like it is "thrashing."1.1. Did you check the pagesin/pageouts per second as described in my "Problems from insufficient RAM and free hard disk space" FAQ? The per-second values can only be found using top as described therein.
1.2. Did you check for a runaway process in Activity Monitor per the "Troubleshooting" section in my "Tuning Mac OS X Performance" FAQ?.
The activity you describe (beach ball, heavy disk writing) has to be coming from somewhere, so checking Activity Monitor as I describe in that FAQ should tell you. Find the process consuming the most %CPU as instructed in the FAQ. Post back the result, i.e. the process name.2. You wrote: "It seems to lock itself up with the hard disk clicking and crunching. Is it possible the hard disk is giving up and so is writing at a very slow speed??? "To check this, see my "Resolving Disk, Permission, and Cache Corruption" FAQ:2.1. Perform at least Steps 1-3 of the Procedure section therein in the order specified.
2.2. Also, review the section therein on "Bad Sectors" to see if the "clicking and crunching" sounds you are hearing are similar to those that generally indicate bad sectors.3. If the disk checks out OK per point 2 above, and depending on what you find in point 1.2 above, the process may be an errant Startup or Login Item. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if such an item is causing the problem.
Good luck!

MacBook Pro running extremely slow- something with RAM maybe?

I'm using a MacBook Pro, and yesterday, out of nowhere it stated running extremely slow and constantly freezes. I did some research and ended up looking in the Activity Monitor, and it seemed like I have no free space available - so I deleted a bunch of files and the computer is still running exactly as slow as it was before. My stats on the activity monitor are:
Free: 9.7 MB
Wired: 851.7 MB
Active: 2.11 GB
Inactive: 1.05 GB
Used: 3.99 GB
VM Size: 162.33 GB
Page ins: 541.0 MB
Page outs: 4.02 GB
Swap Used: 10.41 GB
Finder says I have 317.3 GB available. What's the problem here?

Safe mode prevents almost all third-party software from running such as preference panes, plug-ins, extensions, and launchagents and launch daemons. Normal boot lets all that run. So the issue is with one or more of these third-party items. Perhaps you can download EtreCheck 1.9.10 and run it when your system is at it's worst state. Then post the results here for us to check.
Also,
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
