Overclocking G.SKILL Sniper 2 x 4GB F3-10666CL9D-8GBSR on GIGABYTE GA-Z68X-UD4-B3

Seems like it won't budge from 1333 even with more voltage any ideas?

Testing with Memtest86+ LATEST VERSION : 4.20

Not sure what timings are best to play with..

Many Thanks!

Might try at 1600, 10-10-10-28, 1.55/1.58, Command Rate 2T.....if no go there try reducing freq gradually, maybe down to 1466. May have to raise CPU/VTT voltage about .04/.05

Raising voltage to 1.60V, and timings 9-10-9-24 should provide decent results at least.

Thank you
