Hi, i've HUGE problem with M3A78-T and Phenom II X4 940BE.

Basicly, there is option to turn vcore to AUTO in bios right? and to set vcore manually, and there is hardware monitor in bios to monitor your current cpu vcore, right? So here goes:

So, first off i did set the Vcore to AUTO in bios, once in windows i checked in everest (program) that my vcore was 1.49v which is HUGE for this cpu (Manufacturer normal should be 1.35v!) So i instantly re-booted and went into bios.

Okay, so i checked out the vcore in hardware monitor, which showed it was right, 1.49v.

This time i set the Vcore manually, making it 1.350v, and now it showed up as 1.39v in everest! Also, the bios hardware monitor had the same results, 1.39v.

Finally, i set the core to 1.3125v, and now it turned close to the normal voltage...1.355v in everest and bios.

I can't even set the voltage into Manufacturer recommed 1.35v, because my motherboard only supports the voltage in increments of 0.125v (closest i can do is that 1.355) .

Is something wrong with my motherboard ? seems like the voltage settings in bios turns out to be off by a huge +0,040v.

I haven't had a crash once or anything. But this is just bothering me a lot because i'm not sure about the voltages, and i'm scared if my cpu'll fry in couple of months because of wrong vcore.

Last, hope you'll get what i mean as english isn't my first language and i'm not good at explaining things (at least in english:P) And sorry for the long story, can't explain it better :D .

Have you updated your BIOS ?

I don't suggest flashing BIOS unless it is to fix a specific problem.

On the Asus site for your motherboard in the BIOS downloads the newest version includes this in the description,

03. Fix the problem that AM2 CPU Vcore voltage may be incorrect if change CPU voltage in AI Suite,

Also, on the CPU support page it shows you need to update the BIOS to at least version 0502 for your CPU.
