I'm currently running my new system on my old Corsair XMS3 1600mhz memory, but would like to get some new ram to go with the rest of the build. I've got a Z87X-UD4H and a 4670k running at 4.6GHz. Now should I get 2400mhz or slower as I've heard it might make my overclock unstable? Also, which ram would you recommend, I really wanted to get the Corsair Vengence in red to match my board, but the Patriot Venom 2400 kit also looks nice in red and is cheaper.
