I have a system I built in 2010 with only a 6gb kit of ocz ddr3 @ 1.65v and 8-8-8-24 timings. I got a kit of 6gb g skill @ 1.5v and 9-9-9-24 timings. I over clocked my i7 920 to 3.8ghz. I am wondering what needs to be changed in order to keep my overclock or if I should go buy a kit for either 1.65 or 1.5v ram
