[WhiteFireDragon]

i booted at 500fsb 1:1 memory ratio, but i can't get it stable. i didn't know which voltages to increase, so i increased ALL the auto settings currently shown in my template, and it won't even boot. it seems the increase in voltage from those makes it even more unstable, including the vdimm. increased it from 2.0v to 2.1v for the memory and it won't even boot. it's weird how more voltage for the memory actually makes it unstable.

based on the voltage, i'm assuming "MCH/ICH" is the same word for north bridge right? and should i change my memory multiplier from 2.00B to 2.00D? all this does is change the 333 strap to the 400 strap right? i also need help with all the settings i bolded in the template. and is the F6 bios more stable than the F5? i just got this board a day ago, and bios settings are very different than asus boards that i'm use to.

EDIT: i got 500fsb stable by setting MCH core to 1.4v and changing the memory multiplier from 2.00B to 2.00D . but i still need help with the other voltages.
