HyperX X2 Grey Series 4GB (2 x 2GB) DDR3 2133 Desktop Memory Model KHX2133C9AD3X2K2/4GX

Pros: sleek, well built, stylish and does the job and does it good. I couldn't be happier. It defaults to 1333 but you have to set your bios to get higher speeds. I still haven't gotten to the 2133 yet but that's my fault not the memory's...the x.m.p support shows it capable of it but my MSI 890fxa-gd70 only gives me a ratio of 1:4 which puts my memory at 1600 and I just haven't gotten the overclocking figured out yet to achieve 2133. I bought 2 4mb kits and not a hickup yet. I'd buy this stuff all day long and highly recommend it even though I haven't gotten to the advertised 2133 it's not because the memory won't do it, it's because the user hasn't put enough time into getting it there. Of all the HyperX modules I've bought for builds and my own machines, this is by far my favorite. It times well and runs my machine smooth and fast....took me from a firebird to a vette with a swap of memory..even if I never see the 2133 the fact is this stuff runs circles around the 1333 I did have!

Cons: none, I'm perfectly happy and content with this memory..thanks Kingston for another great product
