I am running into an issue here that just doesnt seem right to me. If I try to change from 9x450 to 10x450, I have to raise the Vcore very high just to get it to boot into windows and even higher to get it to start to become stable. Way to high I feel, but I really dont know. I went back to my Dominator 1800's because they are completely stable, the OCZ is not yet.

Here are my stable 9x450 settings:

With those settings I am rock solid in Prime95, OCCT and SuperPi. So I thought I would try 10x450 which is my goal with this MB and my setup. All I have done was to start raising the Vcore. It's scaring me a bit so I have stopped for now.

Vcore to 1.6 = will finally boot into windows

Vcore to 1.6528 = will do 1M S-Pi but only last about 5 sec in Prime95

Vcore to 1.7 area (forget exact number) = will last for about 30 sec in Prime95

I couldnt go any farther because I was too worried and the temps were way to high under load, pushin low 80's.

Is this normal for this MB to need that much voltage for 4.5GHz? Or could it be the CPU that needs that kind of voltage for that speed? I have not touched any of the other settings which may be a part of it. I'm just wanting to know if this is excessive for this speed is all. Any thoughts?

Uhh yeah...you're not gonna be seeing 4.5 stable on water on a QX. Go halfway for 9.5x450 for 4275, with around 1.5v. Most Yorkfields will do 1M around 4600, some with 4700 with pretty huge vcore levels, much like the ones you're trying, but asking for quad prime95 stability at anything near that is far too much.

I'll have to wait for new bios then. The 0.5 multiplier isnt working in the G27 release. Guess I'll have to settle for 4.3 then when they get it fixed, which is cool. I'll be happy with 4.3 if I can get it stable. Thanks Gautam.

low 80s... not very healthy... ive heard some 45nm chips can run high vcore stable, but they need propper cooling. try to get it to 60 and below and youll be fine. 50 or lower would be best. sounds like your cpu wont go any higher...
you could try a bunch of chips and see if you can find one that clocks better... but your asking for a lot i think :D

thanks for posting the detailled settings btw! wish everybody would do this :D
