I hope to achieve 4GHz on 24/7 use but right now i am somehow stuck at 3751MHz. Tried 3.8GHz, longest running stable on Orthos is 2hrs and system will reboot.

The followings are my Genie BIOS setting @3751MHz (Orthos 8hr stable):

Wonder if anyone can enlighten me to get higher clocks. Temps are nt a problem for now. Running the abv with load at 39C. Will post screenies if you guys want.
