I've put back my previous 2400 mhz speed RAM cause i need the other PC up and running for Work and Rendering, but from what i've tried setting D.O.C.P. Profile at 3000mhz i think it was running at 1.35V cause that's the factory settings on the site. I'm pretty new to OC'ing so i haven't really done no Advance Configurations except setting on Performance mode on EZ Tuning.
