@ PangingIII,

Here are my settings. I put MCH Ref on Auto and I the system rebooted and I got a BIOS overclock error. I went back into the BIOS and changed the MCH Ref to 0.745v. I am running through Prine95 small ffts as I type this.

The systems seems to be stable, but my Core temps are at 56 Deg at 100% load.

my Core volts in windows is 1.33v acording to Everest. Here are my Settings.

--++EDIT++--
It seems my setting aren't stable, when I reboot, I get the BIOS overclock error.

don't worry about how many times that you will have to spend testing your bios setting, this is seem to me like you are still new to all these setting, so be patient with all the testing that you will have to do.

i would also say, no worry about your Core temps at full load at this time, the temps seems fine for now and later on you can check it and try to improve it, may by try adding more case fans or try another/better CPU cooler.


okay now try and test this (below) setting only by leaving the rest of the (above) setting unchanged.

MCH Reference..........................: 0.745v ***on [auto] I get a BIOS

this below method is for you only, i try to make this more easy for you and i can monitor your setting at the same time, so that i can help you easier and probably better.

in your bios, bump up the voltage value (from 0.745v. use this value as your starting point) one value at a time, and then retest your setting in Windows and then try restarting to check the overclocking error message, try this not more than 2 value up. if you still get an error, then this time try bump the voltage value down, not more than 2 value down.
and please do post back. there will always be many subject changes and move around from one to another in here, so be patient.
