CMX512-3200LL problems

[CyberHiker]

Old memory: TWINX CMX256A-3200LL XMS3205v1.2/0326098 (Two for a total of 512MB)

New memory: TWINX CMX512-3200LLPT XMS3205v3.1/0437041-6 (Two for a total of 1024MB)

 

Mother Board: Asus A7N8X-Deluxe

Bios version 1.08 (latest)

Memory Settings in BIOS: By SPD (200MHz, 6-3-2-2)

AMD Athlon XP 2200+ (133 FSB)

Windows XP SP2

ATI Radeon 9700

No overclocking

 

No problems with old memory with the same BIOS settings.

 

With new memory, game crashes to desktop. POST occasionally (15-20% of boots) states "Failed Memory Test" and then continues into the operating system with no other error information. Twice while listening to WMA files, the music started "skipping." (Never thought that was possible with digital music file.)

 

If I lower the speed of the CMX512 down to 133MH (same as FSB) the POST error still occurs on about the same, but the game no longer crashes.

If I put the old CMX256A back in, even at 200MHz, all the errors/problems go away.

 

I did the Windows Memory Diaganostic but it did not find any errors.(http://oca.microsoft.com/en/windiag.asp)

 

So, other than no error showing up in Windows Memory Diaganostic, everything points to bad memory. Anything else I can try?

 

Thanks

With a 133 FSB CPU you could not run DDR400. In fact Nvidia and AMD both suggest running the memory Frequency at 1-1 or 100% with the CPU for best performance. I would try and set the memory frequency to run at DDR333 and test the modules with http://www.memtest.org.
