Hi,
I am upgrading the RAM in my rig and am not sure about latency compatibility, looking for a little insight please. I am currently using G.Skill 8GB (2 x 4GB) DDR3 PC3-12800 1600MHz Ripjaws Series (9-9-9-24) with a low latency spec. (no specific # given).... I want to add G.Skill Ripjaws X (2 x 8GB) DDR3 1600MHz PC3-12800 (10-10-10-30) (no idea what the PC3 # is for) with a Cas latency 10. Using a Gigabyte Dual Channel mobo, I do understand how to pair them in the channels but don't understand the timing thing and want to make sure these are compatible in the same board and also know how the difference in timing might affect the performance. Thanks!

To start with the usual warning: mixing ram can give issues,even when exactly the same maker+model+specs.Read,

look at "Just Adding More Dram".

If just for gaming would i just switch to the new set and keep the other as back up or sell it. Having 1600mhz ram with cas 10 means often it's not the really best chips used for it. Don't think you'll notice in performance though.
If these would work together would they both sets start working at the highest latencies,so 10-10-10-30.
