RAM doesn't depend so much on the CPU but more the motherboard. From what I've seen all the major motherboard companies out there (Gigabyte, MSI, Asus..) post a CPU and RAM support list. They do this because some RAM sticks will work with a motherboard and some won't. It's best to look at motherboards and they're RAM support list then decide. I paired a Gigabyte Z68X-UD4-B3 motherboard with 8 gigs of Corsair Vengance at a speed of 1600 and it's great. I knew I wanted Vengence Ram so then I went and researched motherboards that support it.
