I would like to know which one would be faster and better for mild overclocking for a Core i7 & Gigabyte GA-X58A-UD3R. The first is in the Corsiar Dominator range and the other is what looks to be their standard XMS3 range. But the timings do not lie do they? I realise the cooling benefits of the Dominator heatsinks, but I do not think I will push the RAM hard enough for cooling to come into effect.

  1. go with the cl7 should be faster as long as you're not doing a decent amount of overclocking.
  2. Hi newcomer and welcome to the Tom's hardware forum.

    What? £30 more for CL?, get the CL8 you won't see a big difference between both.
  3. I would buy the cheaper ones. You won't notice any difference between them.
  4. Thanks all. I think I may do the cheaper!
  5. Any time, that's why we are here.
