veniteo, I'm pretty sure that everybody runs 64-bit on their gaming machines by now. Also, Hyper-X is not a brand. It is Kingston's name for their ABSOLUTELY AMAZING RAM. Really, Kingston makes some of the best stuff that I've ever come across.
misfitactual,
Your CPU runs a 64-Bit Instruction Set. To put it in simple words, your computer (theoretically) supports 16.8 Million Terabytes, but you can't afford that, nor would your motherboard support that much RAM, as NO CHIPSET FROM 2014 WOULD EVER BE ABLE TO READ AND WRITE THAT MUCH RANDOM ACCESS DATA. But this means that you should probably get 4 or 6GB of DDR3-1600 RAM from Kingston, Corsair, or somebody like them.
