i am getting a new pc and want to get a 1600mhz ram on a z68 mobo n i5 2500k. but i have seen there are more than 1 models of kingston hyperx 4gb x1 sticks based on latency. how do i decide the specific model suitable?
It will depend on your budget. Most of the people opt for CL9 because of its lower price. But if your budget permits, then you can opt for CL8 modules.
