I was going to get the same type of RAM just at 1333MHz, but the clerk at Memory Express suggested I take the 1600MHz version for an extra five bucks "because it's better", so I did.. I don't really know a whole lot about computers, as my entire build was given to me by some really helpful person on another message board. Anyways, when I mentioned I went for the 1600MHz RAM, he told me, "I really suggest you getting the 1333MHz one because you'll need to set up a XMP profile for the RAM to run at 1600MHz".
Could someone please enlighten me? I don't really understand - What's an XMP profile, why do I need one if I'm using 1600MHz (looking at the mobo/ram specs on the website it doesn't mention anything like this at all), what were to happen if I didn't set up a profile, and how can I set one up? Sorry for all the questions, I'm just about ready to assemble this but I might end up returning the RAM and getting the 1333MHz variant instead.
XMP profiles are only for Intel CPUs. The RAM you have will work fine @ 1333 Mhz. which is the deafult RAM speed for your CPU. If you want to go into BIOS and adjust it to 1600 Mhz. you can but it makes less than 1% difference in system performance in my testing.
