thank you all for your advice. i'm pulling my hair trying to get my system stable ever since i flash to this 0602 bios . i'm almost just about to go back to my old dfi 790fx board, but i'm going to keep on trying. my stability problem is that i'm losing overclocking ability, my crossfire setup is flaky or acts weird with this bios, random blue screen, and one little change in the bios and the system is completely unstable. this is getting frustrating. i guess asus board's never good for me. i wonder if i can sell it for cheap.
