Tuning the 975x memory: surprising results

Since I begin to overclock my system, I leave the memory latencies relaxed at 5-5-5-15, because I didn't wanted memory problems. But some days ago I tried some new setting:
Original settings: 333 x 2 x 1.25 (835 Mhz) - 5-5-5-15
New settings: 333 x 2 x 1 (666 Mhz) - 4-4-4-12
I knew that, at the same 5-5-5-15 latencies the difference in bandwidth between 666 and 835 mhz were about 5%, so I was very surprised when with the new settings the memory bandwidth improved, despite the lower frecuency. Then I tried (obviously) this new settings:
New settings 2: 333 x 2 x 1.25 (835 Mhz) - 4-4-4-12
And the surprise was even bigger: it was a little better than the original settings, but the overall perfomance was lower than at 666 mhz with 4-4-4-12.
I didn't do an extensive perfomance testing, but I've tried SuperPI and Sisoft Sandra's processor benchmark, and the numbers were about the same with all configurations, but the memory bandwidth, according Sandra, was better with 666 mhz - 4-4-4-12, and about 6500 MB (with 835 mhz - 5-5-5-15 was 6300 MB). I've tried many times and also tried Everest test, and the pattern was the same.
Anyone has a theory to explain this ??
Note: the maximun memory bandwidth I've got was 6700 (with bios 7.5 or newer), when my system had only 2 GB (5-5-5-15). When I've installed the other 2 GB, then dropped to 6300, so I regained some bandwidth now...
Note 2: 4-4-4-12 are latencies supported by the memory

Last report on this is...all problems solved...still running as reported, 9*333 with 1.25 RAM multi @ standard voltage with no locks or any other BS! Rock stable, temperatures on idle (30 degrees ambient) 42-38-36-40, max out with all 4 core employed, 57-49-47-52, run all night long with no one BSOD or anything! Tested with Vista X86, Vista X64, Ubuntu 7.10 in both flavors, Sabayon 64...even I give it a go under OS2 Warp 5...very surprising result! Tested with various benches, but I'll just point out my Everest which claims that this is nearly the fastest of all on their list! I am very pleased with final findings and all it's missing would be employing Core center where I could chose few profiles accordingly! Then this machine would be surprise of all time! If this works out as promised there would be no end of my pleasure using it! Excellent finale! Advice to anyone, if doesn't OC, check the CPU as having Core2 doesn't mean it will reach sky high! I had lot's of issues and nearly all of them was solved simply by replacing the Allendale in one shot! Great board, as I said once earlier, and pity thee is EOL on this mobo!
Thanks MSI!
p.s.
does anyone knows of any utility which can change clock and keep few profiles in it...thanks again!
I think you should re-apply the thermal paste on your processor, because the temperature difference between cores is too great. Anyway they are pretty low, what cpu cooler are you using ??

Relative size of sga_max_size and sga_target to the physical memory

Dear Experts,
I have installed oracle 10.2.0.4 on AIX 5.3 with 32 GB of physical memory.
Let us say other applications on the server consume 10 GB of physical memory.
Now how should i plan the size of SGA_TARGET and SGA_MAX_SIZE on the same.

As per Oracle® Database Performance Tuning Guide 10g Release 2 (10.2):
You must then divide the resulting memory between the SGA and the PGA.
For OLTP systems, the PGA memory typically accounts for a small fraction of the total memory available (for example, 20%), leaving 80% for the SGA.
For DSS systems running large, memory-intensive queries, PGA memory can typically use up to 70% of that total (up to 2.2 GB in this example).
Good initial values for the parameter PGA_AGGREGATE_TARGET might be:
For OLTP: PGA_AGGREGATE_TARGET = (total_mem * 80%) * 20%
For DSS: PGA_AGGREGATE_TARGET = (total_mem * 80%) * 50%
where total_mem is the total amount of physical memory available on the system.

One year later, I still have problems with the 975X PUE

A year ago, I bought the 975X PUE board and turned out to be one of the biggest mistakes I've ever made when purchasing something computer-related.
To start with, the board didn't recognize the OCZ memory that I had bought, so I had to change it for some gSkill memory. That, however, involved a trip to Argentina since at the time it was very hard to get DDR2 memory @ 800 Mhz here in Uruguay. I had also complained about how the temperature monitor was unreliable and problems booting the computer.
I still have those problems, but I learned to live with it since no major problems arised. Sure, I'd have to boot three to six times just to get it running, but hey, no big deal.
Later, I decided to go for RAID1 and surprisingly, it worked so I had no new complaints.
However, lately something new has been happening. The computer seems to reboot randomly and without warning. This had happened before when lightning struck nearby (I blamed it on electro magnetic something) but now it happens all the time and I can't find a solution. I leave the computer on during the night and in the mornings, I come to find that it has rebooted when I was sleeping.
Here's what I have:
MSI 975X PUE (7.1083006)
INTEL E6600
GSKILL 4 GB DDR2 800 Mhz RAM
WD 320 GB 7200 RPM
2x WD 500 GB 7200 RPM (RAID1)
NVIDIA 8800 GTS
Windows Vista 32 bit
PSU Biswal 780W 30A +12V
I've looked over the latest firmware thread that used to be a sticky on here and noticed that everything else seems to be beta. MSI never released something better for this board? Here's that thread: https://forum-en.msi.com/index.php?topic=99818.0
The only thing that I could think of for these random reboots is that maybe the unreliable temperature sensors fool the computer and make it seem like the CPU is a lot hotter than it actually is. I've fired up Everest and right now, with only Firefox and a couple of IM clients running, CPUs are at 50 and 54 degrees celcius. Taking into account that the case is open and I'm in an air conditioned room set to 24 degrees celcius and that there's a mini Typhoon on top of the E6600 as well as a couple of fans in the case, these CPU temperatures are nearly impossible.
What's going on with this? Can anyone help me out?

Quote from: daiver on 04-January-08, 21:59:50
Ok, lets say my PSU is degraded. That solves my spontaneous rebooting issue. How about everything else?
I still have to boot my PC 3-6 times to get it to start. Temperature monitor still sucks as well.
Is 7.1 the latest official firmware for this high-priced mobo?
Daiver the biswall brand is a very cheap one, I think you should buy a trusted PSU. In Argentina you can find many brands, like Topower and Power Cooler, that are good PSUs and at a fair price.
The latest bios for this mother is 7.7, but some users find it not so good as 7.6. I use 7.6 and works perfect.

The disk configuration is not insync with the in-memory configuration. Software RAID 1 reactivation

In trying to reactivate disk 3 of a raid mirror failed redundancy I get the error - The disk configurationis not insyncwith the in-memory configuration. The drive is accessible but I have no idea which of drive 2 and 3 are in use, drive 2 has unspecified
errors but there is the option to reactivate disk 3.
Does anyone have any idea what this means?
I am running on a HP Proliant ML350 G5 with Windows Server 2012
Thanks

Hi,
Since the Disk 2's status is Errors, we could not reactivate disk 3. Please try to reactivate disk 2 to check the results.
If the disk does not return to the Online status and the volume does not return to the Healthy status, there may be something wrong with the disk. You should replace the failed mirror disk region.
For more detailed information, please refer to the article below:

My external HD increases the kernel_task memory usage.

I use an external firewire hard drive, SmartDisk FireLite, on my eMac.
the kernel_task memory usage (RSIZE) goes up to over 400MB,
whenever I connect my external hard drive to my computer.
normally, the kernel_task uses 100 to 150 MB
with all scanner, printer, keyboard, mouse, and etc connected.
soon after I disconnect the external HD,
the kernel_task memory goes down to the normal usage.
I don't know how kernel_task works, so I am not sure if the issue is normal...
Does any kind of external hard drive take a lot of memory for kernel_task???
If I use a USB hard drive, this won't happen???
400MB for kernel_task is a lot to me,
especially when i try to use softwares like photoshop, indesign, and etc...
so, if I could save the kernel_task memory, it would help me tremendously.
I would really appreciate it if you could give me any suggestion or answer.

Thank you very much for mentioning the application.
I've already downloaded and tried the shareware.
It was great and provided more free space after running the program,
I am pretty satisfied with the results I got.
In fact, it gives me about 250MB more in free space on average.
It would almost cover the memory loss caused by my external HD.
However, I still hope there would be a way to stop my external HD eating much memory...
Recently I found my ipod shuffle which I've also used to store files won't affect the kernel_task at all and barely use memory...
I was thinking to get a new external HD as an option,
but I am worried if the same problem would remain with the new HD...

We just recently increased the available memory from 8GB to 24GB to help ensure that there is enough memory. This error never happened on CRM v4. According to the resource monitor, SQL is only reserving 20.7GB of RAM and there is 694MB of RAM in Standby.
The main Async service is using 660MB and the maintenance Async service is using 265MB.
To resolve the issue temporarily, I restarted both Async services this morning. Shortly after everything came back, they were holding fairly steady around 350MB and 200MB. It's been six hours since then.
The last time I spoke with Microsoft about a similar problem, they suggested increasing the amount of RAM.

It became more and more of a problem. It was impacting the users in a more subtle way at first. You couldn't configure the CRM for Outlook client. After a while, they couldn't use CRM in Outlook at all and users reporting not being able to complete phone
call activities. I opened a ticket with MS and they suggested the same as Wilson Lou did. The organization error had nothing to do with the creep on the async services usage of RAM. It was indeed caused by SQL stealing all of the memory. Limiting the max usage
to 24GB RAM has resolved that error.
My Async processes are still using a LOT of RAM, but now that I have more than enough RAM, it doesn't seem to be a problem anymore. They are currently using about 700MB RAM each.
Also, I have upgraded to SP1, UR2.

Viewing the printers memory

Is it possible to view the printers memory content through the computer, or in any other way without having to actually print the whole memory content?
I have a: HP Officejet 6500 E709n
Thanks!

DVDs are standardized so they can play back in many kinds of equipment, and the standardized video format is mpeg-2, which is a compressed video format (more than half of the original video data is tossed during the compression process). That said, many factors can affect the quality of the resulting video. Shorter videos (under an hour) will almost always look better than longer videos (except in Hollywood where they have a few more resources than we do) because there's less material to compress onto a DVD (which has a fixed size).
How long is your video? Are you using Best Quality, Best Performance, or Pro as your preference? What are the symptoms of imperfect clarity?

Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Then reboot. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
If you're using Time Machine to back up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as "Backups." The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.
To locate large files, you can use Spotlight. That method may not find large folders that contain a lot of small files.
You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
Install ODS in the Applications folder as usual. Quit it if it's running.
Triple-click the line of text below on this page to select it, then copy the selected text to the Clipboard (command-C):sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders. It may take some minutes for ODS to list all the files.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with ODS, quit it and also quit Terminal.

I got the info that the blod process is lsm1 and lsm2.
although the PGA usage is fine the these process. but it used most of the physical memory.
How to tuning the LSMn. Is it due to some misconfig of laod balance? the server memory is going to exhaust.
Thanks.

Oracle uses shared memory and most UNIX utilities do not properly report Oracle process memory usage due to double counting of shared memory. Are you getting errors? If not, I suspect the figures reported by TOP are not correct.
What platform are you on?
Any errors in alert.log or in the lsn background dump destination trace files?
How is overall system performance?

How much real world difference would there be between the 1600MHz memory of a 4,1 Mac Pro and the 800MHz memory of a 3,1 Mac Pro? My main app is multitrack audio with Pro Tools. Thanks so much.

How much real world performance difference would there be between the 1600MHz memory of a 4,1 Mac Pro and the 800MHz memory of a 3,1 Mac Pro? My main app is multitrack audio with Pro Tools. Thanks so much. The CPU speed of either one would be between 2.8GHz and 3.0GHz.

What are the differences.... firmware and build, there were tweaks to the PCIe bus itself. As a result 3rd party cards and booting is better.
Support in 5,1 firmware for more 56xx and W35/36xx processors. Also memory timing.
The 4,1 was "64-bit boot mode optional" and 5,1 was default. I don't know if there are changes but I assume so, even if it is not reflected elsewhere or in version number.
I don't know what the prices are but 2009, to buy one today, when the 2010 is $1800.
The 2008 of course was test bed for 64-bit UEFI and it sure seems even Lion and then ML are not as well engineered - outside of Linc who would be the least likely to have a problem.
I would assume 2010 has better support for 8GB and even 16GB DIMMs as well as for 1333MHz.
Nehalem family had only come out in fall 2008 and a lot of work went into making improvements well past 2009.
If you remember, there were serious heat problems with those and 10.5.7+ up thru 10.6.2 even with iTunes, audio, and hyperthreading and cores hitting and staying in 80*C range. That I assume was both poor code (sleep does not mean poke and ask constantly) as well as changes in SMC and kernel improvements, to work around. Microcode can be patched in firmware, kernel, by drivers and by code, but it is best when the chips and core elements don't need to be.
If someone is stretched, and can get 2009 for $1200 it might be a fine fit. That year offered the OEM GT120 which isn't really as nice and matched for today both OS and apps that rely on a GPU. And for odd reasons two such 120's don't work well in Lion+ but that is probably minor. Having the 5770 is just "nicer" though.
There are some articles about trouble booting with PCIe SATA/SAS/SSD and less trouble with 2010. Also support for graphic card and audio I think was one of those "minor" 5770 related support issues. But shows some small changes were made there too.
I wish someone would come out and pre-announce DDR4 + SATA3 along with PCIe 3.x (for bandwidth and more power per rail) along with say Ivy Bridge-E socket processors was going to be this summer's 3 yr anniversary and to replace the 2010 designed motherboard. But that is what is on Intel's and others drawing boards simmeringn in the pot.

Reboot problem when OC the 975X Power Up

I don't want to break any OC record, only want to reach 3 Ghz, but without rebooting problems. Is there a BIOS version that fixed this problem ???. I am currently using the latest (7.3A), and despite now I can set the memory in 1:1 mode (with 7.2 I can't), when I set the FSB to 333 the reboot problem arise. In fact the reboot problem occurs when I set the FSB higher than 310-315 mhz. At 3 Ghz the board is rock solid and run all test, and even the memory at 667 mhz perform equal than 777 mhz (310 * 2 * 1.25). I have to note that the voltages are all stock, and C1E and speedstep are enabled (at 2.8 Ghz works great), do you have any suggestion with this items ??

memory compatability . i tried 3 different sets of memory ranging from 533 - 800 mhz ( what the board supports ) the samsung 533 5,5,5,15 reboot issues , Ocz 667 5,5,5,15 no reboot issues up to 400 fsb ( its when i break 400 + is when i need to safe mode the bios ) but this is memory getting pushed to hard . and crucial 800 4,4,4,12 reboot issue but the mb remembers my fsb beyond 400 + fsb ( no safe moding the bios on a shut down ) but because of the compatability issue with the crucial i cant break 400 fsb because it wont hold it . the ocz i can do 430 easily . again here we are . is it mb manu , chip set manu , or mem ? me i am goin towards Memory manufacturers because it is there job to make sure there chips work on multiple platforms and keep up with the times . the only thing we can do too help is contact the memory manufacturers tell them our problems rma our current memory and hope they listen to us .... again ITS NOT MSI fault that memory wasnt cut for a peticular chipset they use .
After reading at many forums it seems to me that the memory problems with 975x/965 chipsets are widespread across all motherboard makers. I don't know if the AMD platform is having many problems with high perfomance DDR2 memory, but at the intel side is a nightmare, and I believe is worst with the 975x than 965.
What model is your OCZ memory ??, Value Pro or Gold ??, if Value Pro, has the copper heatspreader or XTC heatspreader ?? (as mine and not even OCZ support can identify...). I am very curious because with it you don't have the reboot problem, and I do have >:(

HT1423 I am adding more memory, should I replace the top two slots with the 4g memory modules, then place 2g memory modules on bottom slots. Does it even matter?

How do I delete stored email addresses in my iphone? When sending photos, I don't want to have certain email addresses "popping up" from the internal memory, I've deleted my entire "Contact" list but they still appear. Help please!

How do I delete stored email addresses in my iphone? When sending photos, I don't want to have certain email addresses "popping up" from the internal memory, I've deleted my entire "Contact" list but they still appear. Help please!

As with the Mail app on a Mac, the iPhone's Mail app stores all email recipients in a list of previous recipients which is separate from the address book or contacts. The email address autofill feature when addressing an message pulls from Contacts and from the list of previous recipients.
Different from the Mail app on a Mac, there is no access to the list of previous recipients with iOS on an iPhone, iPod Touch, or iPad to remove a previous recipient from the list, or to add a previous recipient to the address book or contacts that is not already entered - not at the present time anyway.
The only way to purge the list of previous recipients at the present time is by restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, which will start being re-populated again with every sent message.
