Well, i'm no OC genious, but i heard that tighter timings beat Mhz. Correct me if i'm wrong.
My Ram are G.Skill F3-12800CL7T2-12GBPI.
DDR3-1600 PC3 (*CL 7-8-7-24-2N 1.5 Volts*) *Stock
I'm running these at 1066 mhz and 5-5-5-18 so far. Not done OC'ing them, i had them at 1600 mhz but they didin't like to go under 7.
Any tips would be appreciated if any.
