aww damn that stinks, do you know the performance difference between the two timings? perhaps if I change the timings the motherboard auto adjusts the voltage with it... I did adjust the timings to 5-5-15 and ran it awhile for 15 minutes but switched it back to Auto so I could consult with you guys before doing it again.
i run on
AMD Athlon X2 3800+ Windsor
Asus M2V Mobo
2gig (2x 1g) G-skill PC2 800 memory
ATI Radeon X1950 PRO 512MB
While memtest86+ (not to be confused with "memtest") is a good test for low-stress conditions, you really need to also test under stressed conditions using something like Orthos before declaring the system stable.
They're different programs. memtest86+ does thorough tests including specific bit patterns chosen to maximize detection of any errors, it's currently maintained, it doesn't require an OS, it's free, etc.
There are a number of "memtest" programs out there. I think one is an obsolete (not updated) program similar to memtest86+ and I think another is a Windows program.
When people refer to "memtest" or "memtest86" on this forum, they almost always mean "memtest86+", but it's nice to get the name right so novices don't go off searching for/downloading the wrong thing.
