Problems with P95 on new system.

keboman · 2006-01-12, 05:52

Hey guys.

I'm having a heck of a time getting my new system prime stable in windows.

The system is:
3200+ Athlon 64
768mb RAM (512mb pc3200 BH5, 256mb Crucial PC2100)
DFI NF4-DAGF motherboard
Soundblaster Audigy2

The memory works fine in memtest on this machine and my previous machine (NF2/barton) used another stick and was prime stable at 400mhz fsb at the same timings.

The problem I'm running into is this:

I basically always have the same result.. if it makes it past the first few minutes it will continue running. I do not have this problem running Mersenne Prime Test from my bootcd and it works overnight just fine.

Any info. would be appreciated.

Well, I take that back. My current run crashed at 53 minutes with the same error. Last night it ran the full 6 hours while I slept. I'm going to pull my Audigy and kill all background processes and try now, if anyone has any ideas please let me know.

This is what I get if it passes the first minute.

It passes 896k in the test from the boot cd, I just double checked it (it runs the test on linux I guess) and I know it can run it overnight. Sorry for the

So is it all OK now?
Anyways I would suspect a problem with your memory. The motherboard you have, supports dual-channel memory operation, but that would require two sticks of RAM which are the same. Single channel operation is also possible - consult your motherboard manual on how to configure your RAM in such case...

keboman · 2006-01-12, 10:41

No, it won't pass prime95 in windows still. Memory is in single-channel mode.

Relax you memory timings in BIOS. First check what does CPU-Z report on current settings and SPD values, then go for the highest of the two modules... you can also try setting either 3-3-3-8-2T or 3-4-4-8-2T and see if that helps - then you can gradually improve the timings to obtain the best stable conditions.

I dropped it down to:

and the behavior is identical

next I'll try just the 256mb DIMM, already tried it with just the 512mb.

OK, I've just noticed it now, you are mixing DDR200 with DDR400 memory, and running both in DDR200 mode which is degrading your system performance anyway... My suggestion is: get rid of this 256MB stick - this is an outdated piece of hardware right now

and run the remaining 512MB in DDR400 mode.

keboman · 2006-01-12, 13:12

No, I just tried that. I run DDR400 normally. Sorry I wasn't clearer :)

I think I may have figured it out if prime doesn't crash this time..

According to CPU-Z screenshot you've posted you are running your system memory at 100 MHz, which means DDR200 not 400.
