GA-870A-UD3 voltage issues

So I have a Gigabyte GA-870-UD3 on my hands, with an AMD Phenom II x4 955 BE, and a Corasir Hydro H70 cooler. Right now I have it stable @ 3.8 GHz, but at the stock voltage of 1.35v. If I try to increase the voltage through the BIOS, Windows will not boot with those set voltages (of 1.4125v @ 4GHz (200 x 20)). HOWEVER! In AMD Overdrive, I'm able to set the voltages, and it runs fine after I set it. I don't want to have to do this everytime my computer boots, so I was hoping someone could help me out? :-)

Thanks in advance

Hi.

Take a look of this: http://www.tomshardware.com/forum/258573-29-black-editi...

Read it and let me know if you have specific question of problems that you can't find in the guide.

Btw, don't use AOD for overclock the CPU always do it from BIOS.

The problem with my board is that I can set the voltages, multiplier, NB clock, every perfectly fine in the BIOS, but the only thing that doesn't stay set properly when the system boots is the VID. I'll have it set to 1.4125 in the BIOS, and can go back into the BIOS after booting 1, 2, 10 times after and it will still say that it's 1.4125, but AOD, CoreTemp, AND CPU-Z all say that the voltage is only 1.35, and it doesn't stay stable @ 200 x 20 (4GHz). Once I set the voltage to 1.4125 in AOD, the system will stay stable, and easily run Prime95 for hours and hours on end, not touching anything higher than 53-54 degrees.

Help?

EDIT: Thanks for the quick reply

Hmm... This seems awful suspicious. In CoreTemp and AOD, it still reports as being at 1.35v, but CPU-Z is stating 1.424v. However - It does seem stable now all of a sudden @ 4GHz, especially during Prime95.
Thanks! :-)
