The review of the HyperX modules doesn't work, and it is a 4x1GB kit, not a 2x2GB. http://www.ebuyer.com/product/133709
is the 2x2GB kit. The HyperX kits are generally good overclockers, and these ones are certainly going to be enough for your system. Just try to find that kit with your supplier (he should have them if he is stocking the 4x1GB kits).
