Prime95 Questions and discussion

Alright, I normally stand by the accuracy of the results of a system being 'prime stable'. But since I've moved from AXP to A64 this has been slowly diminishing.

I keep getting errors after 15mins+ with my setup no matter what voltage, no matter what FSB or memory timings. This all starts happening at 240HT (239 is prime stable... but 240HT isn't... even with a low LDT).

Is there something I'm missing here.... i've read through a few A64 overclocking guides but nothing is helping.

Worst thing is, the system is stable in every other test I throw at it.... just not Prime.... which worries me as I'm finding it hard to completely trust the system.

yeah A64 is a pain in the ass to properly stress test and test for stability especially if the lower multipliers don't work in bios or aren't retained by clockgen on reboot.. tried stresscpu http://i4memory.com/showthread.php?t=79 ?

also sometimes i fine changing AGP lock from 66 to 67 stabilises the cpu and sometimes it doesn't heh

My system boots at 201mhz HT, 67 AGP for my locks to work.... so thats always the case.

But yeah, I seem to have found one big stability issue. My TWINX Rev1.2 (CH-5 I believe) is now priming fine at 224mhz (better than the previous best of 217mhz prime stable EDIT: Forgot to mention, 224mhz was done with 2.74v.... previous best of 217mhz was done with 2.94v). All I did was accidentally up the Ras to Cas to 4 instead of 3.

But yeah, i've been using stresscpu since I saw you post it somewhere (here or OCAU.. can't remember :P). The system responds alot better to stresscpu...

Also, one thing I noticed... reading the Prime95 help file it states that it may not always be accurate with its errors.

Yep, I have long discarded Prime95 as a system testing utility since I went to A64 due to errors at low FSB.. Come one, what a crock of crap :P

Now I use Stresscpu exclusively along with memtest86

prime still has a place i find particularly with mem (blend test) rather than cpu stability which stresscpu is better at for AMD64 + memtest86+ v1.25
