Hello, I'm still new to over-clocking and am in need of some help. I read in multiple forums of ppl getting 4.2GHz stable on air cooling no problem. I would like to hit the 4GHz mark myself and cant seem to get past 3.8GHz. I have tried to up my voltages and still cant get it stable. Also, i bought some G.SKILL memory and it is said to run at 2000MHz at 9-9-9-27 and i cant seem to get it past 1600MHz. I went to the MSI website and bought this ram bc it was one of the ones they recommended. The MOBO supports up to 2133MHz. if anyone can give me some suggestions on where to start it would be appreciated. I have overclocked one other computer b4 but the MOBO was crap and so i decided to just update everything at once.
