Corsair Memory Problems

[jfrog]

Hello. First post here. I have a AMD XP 3200+ system with an Asus A7N8X-E motherboard. I recently installed Corsair XMS TwinX memory modules in a dual channel configuration, and my computer started crashing with the blue screen of death (Windows XP). Sometimes, the game I'm playing crashes, but not the computer. I tried the recommended timings from Corsair, and slower timings, with no change. So, I RMA'd the ram and got it back tonight. I installed it, same thing again:|. Surely the ram can't be defective again, but my computer runs fine on Kinston Value Ram also in the dual channel config. Any suggestions, or am I unlucky enough to receive defective ram twice?

Ram in question: Corsair XMS TwinX1024-3200PT DDR PC3200 512MB x2
null

Ram that I'm currently using: Kingston Value Ram DDR PC2700 512MB x2

Can you test it in another machine?

Run memtest...it might just be the timings or something.

Memtest will tell you if it's something like that.

I've never had a problem with XMS, plus they're factory tested... is your PSU giving you stable voltages?

Crank memory voltage to 2.7 volts and try now

I have the same mobo and using TwinX1024-3200C2. You CANNOT use default SPD memory timing with this memory on this mobo. Corsair has a page with exact settings they've tested their memory on various mobos. The page is located here: http://www.houseofhelp.com/v2/showthread.php?t=38150&highlight=xms+qualification

If I use default settings then the system BSODs.

I use the following settings according to their recommendations and it's rock stable:

Testing parameters for TWINX3200C2:

TWINX1024-3200C2 Data Sheet
TWINX512-3200C2 Data Sheet
Motherboard make and model: Asus A7N8X and/or Asus P4C800/-E and/or Abit IC7.
Each pair is tested and packaged together using the following settings:
DRAM Clock: 200 MHz
SDRAM CAS Latency: 2T (2.5 on AMD platform)
SDRAM RAS to CAS Delay (tRCD): 3T
SDRAM Row Precharge (tRP): 3T
SDRAM Active to Precharge Delay (tRAS): 6T
SDRAM Bank Interleave: 4 Bank
All other settings are motherboard defaults.

I tried the voltage thing already. I,ll try the Bank Interleave thing and see if it works.

I plan to run Memtest 86 later tonight when I go to bed.

Thanks for the quick reply!

SDRAM Bank Interleave: 4 Bank

This setting dosen't seem to be in my BIOS. I updated to the 1013 BIOS revision from ASUS's website. I looked under advanced chipset settings, where it should be, but it isn't there. Is it named something else, or am I missing something?

My corsair TWINX1024-3200C2 runs fine on my ASUS MoBo at 2.5-3-3-6 without a problem.

You know that on an AMD system it is meant to be run slightly slower than intel. On AMD, it should run at "2.5-3-3-6" i think.

I don't think that setting exists on the Asus A7N8X-E

 

[jfrog]

I didn't think so either. I found some threads at random forums discussing major compatibilty issues with my motherboard, processor and ram combo. Nothing I tried would keep it from crashing. I bit the bullet and got a better motherboard and processor, a Gigabyte K8NS-Ultra 939 and Athlon 64 3500+ Socket 939. Funny thing is, the processor comes up as a ClawHammer in CPU-Z...

I just wanted to say no more problems with my ram. It's running fine with the Athlon 64.
Thanks for all the help
