Don't bother overclocking memory, the difference is so small you would never notice it anywhere expect benchmarks; even then it's extremely small. Just buy some DDR3 1600 with low timings such as 9-9-9-24 and you're set.
Yes but as you can see my mb support 1333mhz and for rest need to oc.So i want to oc for sure because from 1333 to 1866 is a small difference but it is.So i should buy 1600mhz to oc at 1866mhz?
That one you suggested me are already 1866 so on my mb they will work at 1333 or i can buy that one and oc to 1866?
Guys is so hard to tell me wich product model need to buy to oc to 1866mhz?
My mb support maximum 1866(OC) that mean if i put an 1866mhz ram in my computer it will work at 1333mhz only.At the moment i have 2x2gb at 1333 and iwant to put 2x4gb
Oh another question.Can i oc the ram without changing the clock of cpu?Because i have a AMD FX4150 wich is by default to 4,2ghz and i don't know if he can handle more than 4,3ghz anyway my cooler will not handle for sure only with crazy rotations.
