With Windows 7 hitting the shelves we were hearing that the amount of ram in Windows 7 is just as important as raw ram speed. So to that end we got a couple of 8GB kits, installed Windows 7 and ran some testing. We ran our normal test suite on the kits then ran further testing using 2 sticks of ram (2x2GB) then the whole kit (4x2GB). That way the exact same ram is tested with 4GB and 8GB and the testing results should be about as good as they come.Corsair was nice enough to send over a 8GB kit of Dominator 1600MHz for our testing enjoyment. We like Corsair Dominator ram, the black IHS (integrated heat spreaders), the performance, the lifetime warranty, the excellent support forum. There's little not to like about Corsair Dominator ram. Lets see how 4GB density fares against 8GB density.
