what is the best ram for the 2600k, asrock extreme 4 gen 3 combo?
I currently have the 2000 MHz dominator that I used with my 1366 system 6 gigs of, will this get me in to the 5 GHz club + or what's better if any? I know I can only use 4 gigs of the ram

thanks alf, my cooling is top notch
my memory needs 1.65v, think I might get rid of it and get some 1.5v stuff
