remote chance of a problem? - Page 2

The images below are 1600x1200. Didn't think about the size until it was too late; shrinking them makes the text unreadable.

This link shows the error as repeatable by just doing a start/stop.

This is a two day torture test.

I'll be doing a memtest86 over the coming weekend. If doesn't do anything, I'll do another torture test with the fsb upped from 200MHz to 209MHz.

Very strange.

Two day memtst w FSB slightly overclocked to better flush out weaknesses.
http://www.eqsrecording.com/rig/x2-memtst-01.jpg
memtst 59 hours passed.

So here is the deal.

I stop then start prime95 v24.14 and it fails once in a while. Same for v24.13. (all hardware settings are at stock).
I stop then start prime95 v23.8 and it never has failed.

Two dual torture tests over 48 hours pass. One test is "blend", the second is "Small FFT's" at 58 hours.

memtst passed.

I don't feel good about running V24.14 so I am running 23.8.

Anyother thoughts on this matter?
Anyone else with an x2 willing to try this? I have nearly 200 hours in testing so this is not for the faint of heart.

Solved.

Not prime95, but requires an AMD dual-core driver.

Description:
Stopping (Test > Stop) prime95 manually then restarting it (Test > Continue) would cause an "ERROR: ILLEGAL SUMOUT" once in a while (perhaps 1 out of 10 times).

Solution:
Download the latest version of "AMD Athlon™ 64 X2 Dual Core Processor Driver for Windows XP and Windows Server 2003 Version (exe)" from here: http://www.amd.com/us-en/Processors/..._13118,00.html.
This driver does more than manage Cool'n'Quiet even if you have disabled Cool'n'Quiet in your motherboard BIOS.

Make sure affinity is set for each instance of prime95 and the stop/restart of prime95 should be fine.
