Hey all, Been out of the hardware game for a while, getting back in with an AMD APU build for 720p gaming on my TV. I'm pretty set on getting the MSI FM2-A75MA-E35 motherboard (with the AMD A8-5600K APU), and noticed that the motherboard states that it supports DDR3 2133 memory overclocked (the exact spec is 2x DDR3 DIMMs support DDR3 2133(OC)/ 1866/ 1600/ 1333/ 1066 DRAM (16GB Max) Supports Dual-Channel mode). So does this mean that I want to get DDR3 1866 and when/if I overclock the APU that it'll attempt to run it at 2133? Or do I want DDR3 2133 (which I assume will underclock to 1866) and when/if I overclock the APU it'll run at it's normal 2133 speed? Lastly, would underclocked DDR3 2133@1866 run any worse than native DDR3 1866 sped'd RAM? Thanks!
