Degrading overclock?

OK, here's the deal.
I have an Opteron 165, DFI LandParty Ultra-D, 2x 1GB OCZ Platinium DDR500.
When I first bought the system, I OCed it to 2.7Ghz, and it was stable. For about few weeks.
Then, suddenly after one restard, the system wouldn't get past the second boot screen. It just loaded most of that page, then locked up, and rebooted after a few seconds. I've fixed it by lowering the OC to 2.6Ghz. Then, after another couple of weeks 2.6GHz became unusable, and now I'm at ~2.4Ghz.
What's causing it, and how do I fix it?
GOing from 2.7Ghz to 2.6 wasn't that big of a deal for me, but not I'd rather be back at 2.6Ghz (or ideally at 2.7) instead of current 2.4.
Help?

PS
Temps weren't and aren't a problem. I have a Scythe Ninja, and the CPU temp never gets above 40*C even after hours of gaming.

This is how the two Athlons that crapped out on me died. The had a sweet overclock for about a week or two, then came the blue screens and then they worked nevermore. A few boots at stock was all they had left in them and *poof*.

I was out about $300+, and never used AMD again.

Ive been using Intel before and since and never had one die on me, or degrade and I overclocked the hell out of hundreds from engineering samples to SUPER UNLOCKED 1-20X unmarked 2.4s that went to 4ghz. That was the sweetest chip Ive ever had (next to my Extreme Editions). I bought it right here on AT for about $100 and sold it for $325!! :shocked:

Now I know AMD quality has vastly improved since I bought my two chips back in 2001 and I was almost going to try them again this year, but now that Ive read this thread and ALL THE PAIN AND HORROR IS COMMING BACK TO ME!!!

(ps. Good luck 2 you )

You guys may all be looking at the wrong issue...I have seen ocing take its effects on the mobo and it power regulations....I have seen this effect to place the cpu on a new mobo and have it go right back to similar OC...

I cannot see 1.425v set in mobo causing this....Temps seem reasonable as well....

I would look at PSU as well...they do degrade...what are the specs of the PSU???


You could do a complete strip down...rebuild...new paste...and rebuild part by part with new install and see if things go back to normal...

As I was reading this I was thinking the same thing. Are you having any wild fluctuations in the voltage?

How would I know that? I've had MBM running at the beginning for a while, and voltage seemed stable. I've never seen it go up or down by more than a tiny margin of error.
