Hey, these forums have been a great help to me, so I want to say thanks first.
Okay, here's what's going on. I had my X2 3800+ Toledo clocked to 260x10 at 1.4 volts and it was totally stable. It was Prime95 stable for 18 hours (stopped it myself) and temps were reasonable, under 50c with full load. It ran this way for the past month with no issues. The system was exactly the same as my sig except I had 2x512mb of Corsair XMS3200PTC2 (2-3-3-6).
Well, I was dissappointed having to run a divider due to the ceiling that I hit with my ram (220), and being year old sticks and wanting to move to 2GB anyways, I ordered the GSkill 2x1Gb DDR500 set in my sig. I had a hell of a time getting these sticks to pass memtest86+, including having to clear CMOS once, but finally did after seeing some settings over at dfi-street. I have run memtest for 20 hours with 0 errors, so I guess the memory is in the clear.
Anyways, after all of this, now my system will not Prime for more than 16 minutes. Either core will fail, or both. If I choose Small FFT, it seems fine, but any other setting will cause either or both cores to fail in 4-16 minutes. Temps seem good, still never going above 50c. I have lowered my oc to 250x10, and it still fails. I tried playing with the Vcore, bumping it up slightly to 1.45, and it still fails in the same way.
What the heck happened? I set all of my settings back to the way they were before I cleared the CMOS, so all of the CPU settings in BIOS should be where they were when the system was stable.
BTW, I have noticed nothing as far as instability in games or other applications, except for the life of me I can't get Microsoft Combat Flight Simulator 3 not to crash when trying to load a campaign.
Also - I'm pretty dissappointed in the lack of overclockability of my GSkills, they won't pass 253 without failing memtest86 pretty badly. I've tried settings other users have used with speeds up to 290 on these, but no go past 253. Anyone else have this kind of experience?
Thanks again, and sorry for the long winded post!!
