Hi there im looking at adding another 8gb of ram to my system. Currently I have 2x4gb of kingston hyperx beast ddr3 1600 cl9. Should I get the same ram or can I put another kingston savage or fury with it? I ask because I live in nz and trying to get the beast ram is hard as they don't stock it. But heaps of places stock the savage aND fury modules. Any advice will be appreciated thanks
