Ok, now Im stumped. I got an E8400 from someone that is suppost to be able to run 4Ghz at 1.1v stable, or 4.5 with 1.38v. Ive tried up to 1.425v so far at 4Ghz, and as soon as OCCT starts, it fails. 3.8 is a piece of cake to get stable though.

I have tried 1.75PLL, 1.15SB, 1.55NB, and 1.35VTT. Only thing I havent tried was the GTLs. Well I tried them, changed each one from stock 110 to 115 and it wont post when doing that.

I figured out how to do the GTLs with this board, but its limited to 1.45VTT. Only got to 4610. I got 4725 to boot, but reset just as I click validate.

finally you found gtl settings..its the secret sauce to wolfdales :D
