Neo2 Standby (S3) & CAS latency issue

I've seen this problem reported with some ASUS boards (and fixed by a BIOS update) but I get it with a Neo2. With a stable stock system to start with, after resuming from a S3 (suspend to RAM) standby:
- CAS 2.0: unstable - Prime95 errors immediately and random BSOD within a minute or so.
- CAS 2.5: stable
e.g. after resuming, 2.5-2-5-2-1T is 100% stable but 2-4-10-4-1T is not.
I've also noticed that temperatures reported drop by 4 degrees or so after resuming but this is a separate issue.
Anybody else seen this and do any specific BIOS versions help? I'd like to be able to run my expensive RAM at CAS 2 - though I have heard (correct?) that CAS makes minimal difference with an A64.

There has been numerous issues with overclocked system and STR
with several motherboards .
Seemsthat there is a flaw in the nforce3 250 chipset.
Obvious solution is not to use S3 .

Mixing Ram with different CAS latencies in K7n2 Delta-L?

I have been using 512mb Kingston Value Ram in my computer, pc3200, with CAS latency of 3.0. I just purchased some Corsair value select 512mb ram pc3200 with CAS latency of 2.5. I know you are not supposed to mix ram with different speeds (like 400 vs. 333) but does it matter if the CAS latencies are different?
I'm running an AMD XP 1800+, K7n2 delta-L, nforce2 motherboard from MSI. Someone at a computer shop told me they tried mixing Kingston 3.0 CAS with Corsair 2.5 CAS, and said his computer wouldn't even post. So I'm wondering if this is an isolated problem, or you will always run into this problem if you mix ram with different CAS latencies.
If anyone has experience with this issue, please share with the board. Thanks!

The age old question, will the components I bought be compatible ? There are those that have bought identical matching memory that didn't work. In my case, I had an ECS K7S5A that used PC2100 Crucial memory, the sticks neither matched (at one time they did, but one stick died and they sent me the closest thing they had.). Neither of these Crucial sticks was identified by a configurator as being compatible with the K7N2 Delta L that I decided to buy. In the end, not only did both sticks work, but I put them in as single channel mode (ram slots 1 & 2), but later changed the configuration to dual channel mode (ram slots 1 & 3, even 2 & 3). It worked flawlessly in all three configurations. Sorry for the long answer, but in essence, there are no guarantees and your worries will drive you crazy. When memory is mixed, you reduce the likelihood of compatibility, even when you go beyond the recommended products that were specifically identified.
That guy at the computer shop, did he ever indicate or isolate the true reason why the memory wouldn't work ? Maybe, maybe not. I would think with a disparity in memory, the bios is the key to setting the settings for the worst stick of the bunch. Then again, the products you get might overclock to what the better sticks run at. My assumption is that mixed sticks, the bios retards settings to this in "auto" mode. When you force it manually, it may work or it may fail. One thing you oughta know, each and every stick has the manufacturers id encoded onto them at the very least, just like the firmware on other items indicates a manufacturer code and other data that allows these things to be compatible. So know you face that battle going in with any of them. If the bios programming doesn't allow it to work, from that perspective, there'll be problems.

P45D3 DPC Latency Issues

I just submitted a Customer Service request.
I see this has been an issue with other MSI P45 MB's. This system is purpose-built for recording, the spikes negatively affect my ability to record at low buffer settings. Otherwise, everything is perfect-very nice MB. Here's hoping they have a custom BIOS to fix this.
MSI P45D3, Intel Q6600, Scythe Zipang SCZP-1000 cooler, 4GB Patriot PVS34G1333LLK, PowerColor HD4650, Thermaltake ToughPower 750, LiteOn 22x SATA DVR-IHAS422-08, WD VelociRaptor 150GB (system drive), Seagate 500GB (data), Seagate 1TB (audio drive), ADS Pyro 1394 card, XP Pro SP3.

Is this a beta or a public BIOS?
When did you submit the request? (nothing happened with mine for the P45 Neo3 latency issue yet)
I submitted my issue to customer service (http://ocss.msi.com.tw/) on 9FEB. I received a reply 10FEB. The BIOS file has been on their ftp site since 23DEC08. It is not the public BIOS (1.6) available for download on MSI web site.
There is a BIOS I believe is for for your board with the same file name type as the one I used on the ftp site. Mine was A7513ICI.101. There is an A7514ICI.101 here: ftp://ftp.msi.com.tw/BIOS/7514/. Up to you if you want to chance it.
DL USBoot.rar from here: ftp://ftp.msi.com.tw/Tools/ follow directions to make bootable USB flash drive. I DL AFUWIN from here: http://www.ami.com/support/bios.cfm and found the newest version of AFUDOS.exe in one of the folders and put that on my bootable USB stick. The version MSI provided would not work for me. Change boot order to USB 2.0 first. Once booted on USB stick syntax I used was: afudos /i(BIOS filename) -no parenthesis when entering in DOS - at first it gave me an error but then it quickly proceeded to execute. I'd back up your current BIOS just in case.
Good luck.

New iMAC giving huge latency issues.

HI everybody,
Im new to these forums as I have just recently purchased an iMAC, 3.06Ghz, with 6 GB of RAM for my studio.
Before this I was running an INtel based pC with Pentium processor, which worked as fairly well and absolutely without any latency issues.
Here's the problem:
i hooked up a MAckie ONYX 1640 mixer with Firewire I/O into the iMac and setting anywhere between 64 samples to 128 samples shows me theoretical latency of between 5 to 8 Ms, which is alright, I used to work with similar settings on the OC and it is hardly percievable. The problem is , the Latency sounds much higher!!
Its definitely not 8 Ms. and with lower buffer sizes, obviously the audio starts clicking and popping.
I then hooked the iMac with my Presonus Firebox which iv used smoothly with the PC for three years, without ever having latency issues...but this time too, the IMAC is adding latency and audi coming back from the DAW is very percievably late. Definitely around 25-30 Ms at such low buffer sizes!
Can someone help me out here, in case there s any optimisation to be done for the mac to make audio its top priority etc, and to better performance?
Highly appreciated!
Much thanks

You poor boy!
Apparently you had some unrealistic expectations.
Many
plugins
just NEED
a lot of
latency
to calculate the processing to the sound. In fact, there is a rough law stating that you can't have top sonic quality and NO latency using software only, especially mastering compressors and reverbs.
You could try the *Low latency mode* button, it also immediately shows you which plugins have a significant latency, as they will be bypassed in LLM.
This is especially true for 'high end' plugins like Space Designer, AdLimiter, Multipressor and a whole load of others. If you need reverb on voice just to have a 'moral support' when recording, choose a 'simpler' reverb, or, better even, use direct monitoring and a HARDWARE reverb that only adds reverb to the monitoring path.
Plugins are meant more for mixing than for tracking.

KTV4 DDR266 memory CAS latency compatability - question

I am planning to upgrade my DDR266 RAM from 512MB to 1GB by adding a 512MB module.
The current module is CL2, but all available upgrades are CL2.5. Supliers all recommend CL2.5 modules. Will I have a problem if I mix CL2 with CL2.5? I have ask a couple of memory suppliers about the CL compatability, but they will not express an opinion.
If there is an issue, I was wondering if setting CAS# Latency in BIOS to CL2.5 will help.

Hello,
You should never mix memory modules that are different.
Yes it can work fine but for optimum performance you must match.
Sometimes both modules will not work together
PC will BSOD a lot
Or it will be ok.
Yes setting the memory timing to CL=2.5 in the BIOS will make the other memory module run at CL=2.5 but there are more timings that just the CAS latency.
All must be the same/old module must be capable of running at new modules timings.
Will the new module be DDR266?
I would recommend you get some new sticks, PC3200 (<will run at 266DDR) 2x512MB and sell the old one.

Does Cas Latency really make a difference?

I have a MSI K8N Neo2 setup (AMD64 3500) and I am inquiring if memory latency effects are really noticible or not during heavy gaming or creating home movies for DVD's. Currently, I have two sticks of Corsair Value Select 512MB DDR PC-3200 (VS512MB400). It has a Cas latency of 2.5. Is there any good noticible performance reason, I should trade up and buy some better performing memory. If so, does anyone have a tried and true favorite with the K8N Neo2? Any thoughts? I have never overclocked, I just run at stock speeds. Perhaps the performance gain is not worth the money?

Spread Spectrum Modulation was invented to reduce interferences of high order
harmonics of the bus frequency. The theory is that, because every wave form
generates higher order harmonic waves or Obertoene, accumulation of the latter
can result in interference with the original signal.
One way to avoid this problem is to subject the base frequency to a slow (ca 100,000 clock cycles) modulation,
meaning that the FSB varies between e.g. + and - 1% of the nominal value.
In older boards, usually two different settings were available,
either centered around the nominal value or set with the nominal frequency as the maximum (low modulation).
Most current boards employ the centered modulation.
This is, at least, the official version of Spread Spectrum Modulation.
In reality, there are different reasons for its implementation.
With increasing operating frequency, electronic components emit electromagnetic interference signals (EMI).
EMI, on the other hand can cause interferences with other devices and is,
therefore, subject to regulation by the FCC which limits the signal amplitude according to its guidelines.
Any device exceeding the maximum allowable signal strength will not gain
approval by the FCC and can, therefore, not be marketed.
In order to understand the reason for SSM, it is necessary to know how the FCC
tests EMI.
Basically, the testing device is a radio receiver and the testing is done by sweeping
its receiving frequency through the frequency range of interest and measuring the
interference with the video and audio signals. The bandwidth sensitivity of the
measuring device is in the order of about 1 MHz.
If the operating frequency is modulated to spread over a bandwidth of typically
4-5 MHz, the same will happen to the EMI spectrum and,
instead of showing a sharp peak, the spectrum will be spread to a more or less
Gaussian bell shape.
In this case, the amplitude will be, of course, substantially smaller, that is,
in the order of 1/3 - ¼ of the original peak.
The energy, however, will be the same. On the other hand,
the measuring instrument with its bandwidth limited to only 1/4 of the spread will,
consequently, only see 1/3 to ¼ of the EMI.
Therefore, the system will obtain FCC approval even if it exceeds the guidelines.
Recommended Settings
If running at stock setting, enabling Spread Spectrum Modulation (SSM)
may reduce EMI, and cause less interference with wireles communication devices.
Under all conditions, enabling SSM may cause a system to crash.
This is especially true for overclocking, simply because with the high multiplier values employed now, even a 0.5% modulation up and down can cause
differences up to as much as 10 MHz clock speed within one modulation cycle.
In other words, if the CPU is already operating at its limit, increasing the clock
speed by another 10 MHz may be fatal.
Therefore, for any overclocking, SSM should be turned off.
Another side effect of SSM is that it can interfere with the clock generator.
This means that, instead of merely initializing SSM, it is possible to enable FSB settings that were never supported by the manufacturer.
Examples are the Tyan Trinity 400 where disabling SSE results in an actual bus
speed of 90 MHz instead of the selected 117 MHz or the MSI 6309 where FSB settings of up to 200 MHz become available.
The reason is that activating SSM can cancel out the FSB setting since there
can be a pin address overlap on the clock generator chip.
(from lostcircuits.com)
Lets say your CPU is putting out EMI , its all concentrated on one "channel/frequency" on the spectrum.
What spread spectrum does is broaden that out to multiple channels/frequencies so it isn't as "potent" or interupting.
http://www.rojakpot.com/default.aspx?location=8&var1=0&var2=115
This is interesting.
Fsb spread spectrum enabled can cause internet dropouts.

WTR310N Latency Issues

I have the WTR310N router, and all of a sudden, I have started experiencing huge latency issues overnight. When I connect directly to the Cable Modem, I am at ~100ms, and when I connect to the router, I am between 1200ms and 2500ms. I have rebooted the router, rest the router, and restarted my computer several times and in various orders. The results are the same each time. This happened last night around 10 PM instantly and has degraded ever since. No changes were made to the computer nor to the router configuration so I am stumped here.
Anyone have any ideas or suggestions that might help me solve this issue?
Thanks and I appreciate all the help I can get.

Well first thing which you need to try is to upgrade the firmware of your Router, Go to website linksysbycisco.com/downloads.........insert model no of your router in serach tab......select proper version of your router........download the firmware file......save that file on desktop...
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...
In the address bar type - 192.168.1.1...Leave the username blank & in password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Now reset your router :
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...
Once you Re-Configure all the settings on your Router, i think this might solve the Problem.

CAS Latency 2 Reverts To 2.5

My RAM is designed for 2.5-3-3-7. I've already changed it to 2.5-3-3-7, but was recommended by someone else with similar memory that I try changing the 2.5 to 2, for more performance. When I set it to 2 it boots and runs fine, but CPU-Z and Memtest86 report it as 2.5 still. The BIOS definitely reports it as 2.
Why?
Is it true that the CAS Latency makes little difference on my system? Why is this?
Specs:
Intel Pentium 4 2.8e HTT @ 3.26GHz
Thermaltake Spark 7+ Xaser Edition A1715 CPU Cooler

Sounds like CPU-Z is reading the IC Chip settings and not BIOS settings.

DDR 3200 Cas latency Settings

I have 2x256 platinum corsair 3200 Low Latency twinx memory. I changed the latency settings to 2.2.3.6. and my pc is now running faster. Does anyone Know the optimal settings I should be running them at? Also what is the Burst speed in the bios.( This is listed right ofter the cas latency section in the bios. I have a choice of 8 or 4 what should I choose

If your system is running faster-you should be happy. Timings vary from system to system depending on bios version and quality of ram. Ideal settings are 2-2-2-5. In reality this is hard to achieve with stability on a Canterwood/Springdale chipsets-especially in the higher peformance modes (ultraturbo). Also ras to cas seems to be far more stable on these chipsets when set to 3(my gut feeling is that PAT is somehow affecting this setting). Memory manufactures like Mushkin recommend that 6 be used instead of 5 for btter stability and less potential data corruption. Finally from what I remember about burst length 4 is more stable than 8 but 8 allows for more speed. I do not think there is a big drop off when using burst 4 as opposed to 8-you would have to use your own testing. Your settings are fine as long as your system is stable. My one question is how sure of you that what the bios is reporting is what your memory is actually running at. This has been a "known" issue with the various MSI bios's. Use and independant reporting tool such as CPUZ to check the validity of your timings. Also as you tighten your timings it is advisable to raise your Vdimm-2.65-2.80 seems to do the trick-especially if overclocking.

Time Capsule stuck at Preparing for Backup, and internet TC latency issue

I have an iMac that backs up to my 1TB Time Capsule. I have had it since March. Suddenly it stopped backing up. It get's stuck at "preparing for backup" and never actually completes a backup.
I am also experiencing a HUGE latency issue with my internet connection. I am constantly having to use the 'refresh' page button in Safari.
help....

TB,
*_Time Machine May Report "Preparing..." For a Long Time_*
Consider these factors regarding an extended period of "Preparing...". Consider each topic separately and do not attempt to act on all of them at once.
*Recent Crash or Other Major System Event* (Deep Traversal)
The reasons for this process are described in an article by George Schreyer. “During the preparation step it checks the FSEvents log for consistency. If it determines that something isn't quite right it has to rescan the whole disk. This can take quite awhile. A full rescan is always triggered by a crash, an unplanned shut down event or by booting from some other bootable disk between backups…. After a crash, Time Machine must scan the whole disk to determine what it has to do because it cannot trust the information that it left behind. Connected via an Ethernet connection, this phase would typically take 20 minutes on an older PowerBook. Being connected wirelessly stretches this phase out to over 3 hours.” [http://www.girr.org/mac_stuff/backups.html]
According to the following KB article it can sometimes take a very long time if Time Machine begins this “deep traversal” and has to compare data inventories. This may apply to your situation, particularly if many Gigs of data are involved. (http://support.apple.com/kb/TS1516)
*Anti-Virus Software*
Running anti-virus software can interfere with the backup process. Either disable it altogether, or try the suggestion outlined here, “If you use third-party anti-virus scanning software and have issues, make sure your Time Machine back up folder (Backups.backupdb on the Time Machine disk) is excluded from virus scanning.” (http://support.apple.com/kb/TS1516)
*Software Updates* #
Installing new software, upgrading existing software, or updating Mac OS X system software can create major changes in the structure of your Macs directories. Time Machine will backup every file that has changed since the installation.
If you take a look at the Console logs Time Machine may be reporting that your backups need "deep traversal". That's fine. Time Machine knows what is wrong and how to fix it. If you have a great deal of data, it may take quite awhile.
After an OS update (like 10.5.5) Time Machine realizes the system no longer matches what it looked like during the previous backup. So it has determined that it's earlier catalogue of what-should-be-where is 'untrustable'. So it is going to go item-by-item comparing the before and after of your system. If you have just performed an OS Update then Time Machine knows what it's doing - let it do it!
*Spotlight Keeps Indexing Backup Drive* #
It may be that Time Machine can’t proceed or complete a backup due to a Spotlight indexing error. During this period, take a look at the Spotlight icon in the upper right corner of your screen. Is there a tiny dot pulsating in the center of the spyglass? Click on the icon. Is there a progress bar displayed? Generally Spotlight indexing is a good thing. But at time it may hang and never progress, preventing backups from taking place.
Go to System Prefs --> Spotlight --> Privacy Tab.
Drag your Time Machine disk into the window. It should now be among the items to exclude from indexing.
Now quit System Prefs.
Reopen System Prefs and remove ("-") the Time Machine disk from the window.
This should clear out Spotlights cache. Naturally, Spotlight should begin indexing again (maybe even for a few hours depending on how much data there is), but it should eventually stop.
*Reboot Time Capsule* #
Stop the backup from the Time Machine menu.
When the Time Machine icon stops spinning, unplug the TC from the wall outlet.
Wait 10-15 seconds.
Re-plug it in again.
After it has restarted (30-60 seconds), attempt another backup.
Time Machine will report “Preparing…” again, but it shouldn’t be lasting more than a couple of hours.
Let us know if any of the suggestions above helped in your case.
Cheers!

Latency issue Logic pro 9.1.3.

Hey,
At the same time as upgrading to Logic from Garageband
I bought a Cakewalk Roland UA25EX ext usb soundcard because i was told
i'd have latency issues if i used the caps lock keyboard for midi
or direct input thru the input jack of
my MacBookPro
(5,3 Intel Core 2 Duo 2.8 GHz)
Sometimes i use the caps lock keyboard to sketch in midi ideas and mostly it's ok.
Other times it's delayed and there's no smile on my face.
When recording with guitars/303/generators DI thru the soundcard
I have latency issues that don't seem to be very regular.
Sometimes it's worse than others.
I make sure i have nothing else running on the computer,
just Logic Pro 9.1.3, so it's not like i'm overloading macbrains.
I have tried all the rebooting, i/o buffer size changing (down to 256), headfones from the mac output/headfones from the soundcard/ etc
but still no luck.
I can record with the low latency button on
and it's kind of better, nearly, but that means i don't get to record with the effects on the channel strip
that affects the recording/playing quite a lot, as i'm used to recording with effects/guitar amps if i go DI.
This was the selling point - that i could record DI wthout disturbing Thee Neighbours.
It seems to have gotten worse recently.
I wonder if it's been corrupted somehow because it also has been acting funny when i bounce down -
the play head is set to 1111 and i save - then in the bounce window
the start position says a silly random number and it takes a few attempts of fiddly changes to get it to stay at 1111...frustration!
Is there something i can do or is this normal? -
it seems weird that a Pro app that cost me so much £s wouldn't work in a simple recording/bounce down set up?
or has anyone else had this problem and fixed it?
If i wipe Logic and install again would i have to go from my Logic Express and then up to my Logic Pro upgrade/extension again?
Any pointers would be greatly appreciated.
Thanks in advance

Hey Fox,
Thanks for that info -well umm, yes i installed the correct drivers.
I use just the AU plugins or the basic logic ones on the channel strip
but even when i was going in dry there was still a delay.
I had experimented with the buffer size, as mentioned, but not gone down that low cus
last time i tried that i had other strange things happen!
But i will try again.
Sample rate was at zero, btw. Always says zero.
But today, when i just opened logic, the sample rate had changed. Strange. I need to understand this side of things so i'm gonna read up.
Also, if plugins are involved, i installed some novation bass station and some freeware TAL bass synth
stuff recently but don't have them up when i'm recording.
Maybe they sit there quietly and interfere just by their facial expressions or sumthing!!
I booted Mr MBP just now and i pulled out the USB and he's shining me a big ole red optical light
out of his output jack!!
In SysPrefs it has only optical digital as an output option.
In the last few days as i was playing around trying to correct the latency issue i noticed that the output options had changed to the UA25 and the 'digital optical' options - rather than the UA25 and 'line out'.
I'm off to go and read up on how to get my line out back, and try this buffer thing again.
Thanks again

Video Latency Issue On The Mac Book Pro 2.4 With Leopard 10.5.5

Gear: Macbook Pro (early 2008 model) - 2.4gigs cpu 2gigs ram - all the latest updates... no other applications running during the test
Hi folks. Currently I am having a latency issue when trying to record directly into iMovie using the built-in microphone and iSight camera. Basically, the video seems 5 - 7 frames late to the audio. I found that a good way to demonstrate this issue was simply doing a few handclaps as a test.
This is a quick handclap test displaying some video latency during recording with the iSight camera in iMovie 08.
- Just download this link — and import it into iMovie 08 - Here is a link to a zip file that you can import into iMovie 08 - It's 2.5meg - .m4v export - Also it was recorded as standard format and audio midi setup app: audio was set to 44.1:
http://www.brainbeast.com/37/clap-1-large.zip
- Play from beginning. As soon as you hear a clap sound — pause with the space bar - then back up before the clap with the left arrows
- Then click the right arrow several times until you hear the beginning of the clap sound ( This is the audio: start frame)
- Now — you will notice the video still has an open hand. At this point click the right arrow, counting as you go several times until you see the hand close. This is the amount of frames that the video is late to the audio. For me it seems to be an average of about 5-7 frames late.
Unfortunately iMovie 06 nor QuickTime will not scrub audio as you go frame by frame with the arrow keys so you cannot test it there. If you have some other application such as final cut Pro, you could test it with that.
! IF YOU WOULD LIKE TO PERFORM THE TEST YOURSELF:
- Just record a new movie in iMovie 08 - using the built-in mic and i-Sight camera — and see if it is also slightly out of sync
Note: to be as fair as possible — I did a slow handclap ( in order to not challenge the frame rates) - also, in order to get the maximum volume I used an open palm ( clap on the palms with your fingers spread out as you can see I did.)
Please let me know if this latency appears to be the same for you as it does for me.
Q: Is it just my machine or does it happen to you too?
Q: Does anyone know a way around this latency issue?
Q: Does anyone know if Apple is aware of this latency issue?

I am experiencing the same incredibly frustrating problem as well. When I record directly into iMovie
'08, the video lags the audio by a fraction of a second.
I have tried shutting down all other applications and having only iMovie up. Same problem.
I tried recording the video into QuickTime instead of iMovie and experienced the same problem. (Which makes me think it is perhaps a hardware or operating system issue.)
I tried the technique suggested here and on other sites of "double-dragging" the clip from the Events pane into a project (one normal drag and one Shift+Cmd drag) so that I had the audio and video as two separate tracks. After muting the audio on the video track, I then attempted to slide the audio over to sync it with the video, but even down at the 1/2 second zoom setting I didn't seem to have enough granularity to move the audio so that it was exactly in sync with the video. I was wishing I could use the arrow keys or something like that to move the audio just one frame at a time.
All I want to do is record a video directly into iMovie '08 - this would seem to be something trivial to do!

BUG with Memory CAS-Latency with MSI i848P Neo-LS BIOS

I have a bug with MSI i848P Neo-LS BIOS. I try many MSI i848P with same trouble : the CAS Latency is always set to 2.0 even if the memory is CAS Latency 2.5.
It doesn't depend on PSU or others things (graphics card,...).
Try with Pentium 4C 2.6 or 2.8
But I have just one brand of memory (but many different sticks). Chips reference are VT56DD32M8PC-5 (256 or 512 Mb). This memory are reference as Cas Latency 2.5
If I set memory timings on SPD or manual : same result !!!
If I set memory speed on AUTO or 400 MHz : same result !!!
If I set other timings, then they are save correctly (ie : RAS# precharge set to 3 or 4).
I check timings with latest version of Memtest86+ V1.0 : http://www.memtest.org/
and of course, I get many errors.
The same memory tested on others mobo, give good results.
I try Windows XP installation and I get.... blue screens.
With some memory sticks : I have this message "memory timing too tighly",
if I press F1 to continue: then I get a memory cas latency of 2.5 with memtest86+ and then no error.
I try BIOS revision 1.0 (default) and 1.2: same result !!!
So, as I said before, I think this is a bug with the BIOS. I agree that a BIOS cannot detect correctly all kind of memory, but if you set memory timings manualy, then it must be set as you want ! ?
Any idea...
Thanks

H0 Alex,
You are correct.I have the same problem with my 875p neo lsr on bios 1.9. TH0S 0S B0OS BUG.but everyone says your psu is not enough or your rams isnt on the MSI Memory Compatability List.
why all of rams I try give same result?
MS0 boards works only with 10 or 20 ram.you don't say customer why you use this rams?
why in asus boards many os these rams working properly.This rams isnt on the MSI Memory Compatability List.but working.I try many no name rams and results are very good in all of the tests.
In my opinion MS0 bioses doesnt work good enough.

Case Sensitivity Issue with Latin Characters

Hi,
The Latin Character that i am talking abt is "i",
I am trying to provide in my application the support for Azeri-Latin(Turkish family) Characters,
That is the display and the orientation of characters is perfectly fine throughout the flow of application.
But now there is a problem when selecting a data from DB using like constraint in where clause... The issue has been elaborated below...
From the set of characters there are two character in which i am facing Case Sensitivity issue...
They are as,
i ---> the capital of same is ---> İ
ı ---> the capital of same is ---> I
now in english character mapping,
for i ---> the capital is ---> I
So, this is creating an issue...
Now the test i have done is as follows,
I created a table as,
Create Table CS
CS1 VARCHAR2(20)
Following is the data that is inserted in the table,
Insert into CS values('İ');
Insert into CS values('i');
Insert into CS values('I');
Insert into CS values('ı');
now i am running the following query,
Select * from CS where lower(CS1) like lower('%&a%');
for characters "i","İ","I" it returns 3 rows, that are,
i
İ
I
and for character ı it only returns,
ı
ideally for characters "i" & "İ" should be mapped with each other and "ı" & "I" should be mapped with each other respectively.
But that is not the case.
I am using Oracle 10g
my NLS_database_parameters are as follows,
PARAMETER     VALUE
NLS_LANGUAGE     AMERICAN
NLS_TERRITORY     AMERICA
NLS_CURRENCY     $
NLS_ISO_CURRENCY     AMERICA
NLS_NUMERIC_CHARACTERS     .,
NLS_CHARACTERSET     AL32UTF8
NLS_CALENDAR     GREGORIAN
NLS_DATE_FORMAT     DD-MON-RR
NLS_DATE_LANGUAGE     AMERICAN

NLS_NCHAR_CONV_EXCP     FALSE
NLS_NCHAR_CHARACTERSET     AL16UTF16
NLS_RDBMS_VERSION     10.2.0.1.0
and at client i m using,
NLS_LANG = .AL32UTF8
any help on this issue will be appreciated,
Thanks & Regards,
Pratik

I'm not fully understand your question but I guess you may need to set up NLS_LANGUAGE, NLS_TERRITORY db parameters and client NLS_LANG.
eg client NLS_LANG=TURKISH_AZERBAIJAN.AL32UTF8 and db parameters NLS_LANGUAGE=TURKISH, NLS_TERRITORY=AZERBAIJAN
Full list of supported languages, locales see [Oracle® Database Globalization Support Guide local data subpage|http://download.oracle.com/docs/cd/B19306_01/server.102/b14225/applocaledata.htm]
or tip2: check this: ALTER SESSION SET NLS_COMP=LINGUISTIC;

or you need something like this:
Example 5-16 Matching with the Base Letter Operator [==]
Expression: r[[=e=]]sum[[=e=]]
Matches:
resume<<
résumé<<
résume<<
resumé<<Oracle SQL syntax: SQL> SELECT col FROM test WHERE REGEXP_LIKE(col,'r[[=e=]]sum[[=e=]]');Edited by: Kecskemethy on Mar 24, 2009 3:20 AM
