Summary: This is very nice memory but a little expensive. The memory was FAST (tested it with memtest)! I used the following as well, speed is almost the same and it's cheaper http://www.amazon.com/gp/product/B006YG9EEW/ref=as_li_tl?
Summary: This RAM has excellent timing but it's not compatible with a lot of 3rd party heatsinks where the CPU fan extends over the RAM tray. If you're going with a big heatsink make sure to get low profile RAM.
Summary: Upgraded my system recently and these seemed to be a good for the money. My brother-in-law liked their look since it matched my new mother board but the clear portion of my case is against the wall so it won't be seen anyway.
