I don't know if one of these threads was started but I'll use this one

My highest was an AMD Athlon XP-M 2600+ @ 2793MHz. (133FSB x 21 @ 2.2VCore). It wouldn't boot into Windows.
The highest I could go into Windows was 2527MHz (133 x 19 @ 1.8VCore). Too bad I corrupted my BIOS on my motherboard, and it will no longer boot

Abit AN7's are awesome overclockers, but their BIOS's aren't very fail-safe for being a fail-safe OCing board.

That was on a huge air cooled heatsink/fan, with Ceramique heatsink compound (very good stuff).

AMD 4000+ Overclocked in BIOS setup by 10% with no problems. About to change Mobo and use AMD 9700 quad (when problem they have is sorted)

I managed to get my C2D to 4.4Ghz for about a minute, before it crashed. I got it stable at 3.8Ghz, but im running it at 3Ghz for complete stability.

core 2 quad from 2.4ghz to 3.7ghz on water cooling, stable at around 35degC under stress

Actually i might go back down to 2.66ghz. I really dont need so much power LoL

E2140 @ 2.8 GHz. I can get it to 3.0 GHz, but I need to raise my vCore from stock voltages >_<

Thats pretty good sniper. They run at 1.6 is it at stock ?
