Summary: Bought this for same day delivery with less than an hour to spare. Amazon comes through and later in hte evening I went from a 2 Gig system to a 6 Gig system. No problems as of, oh, 2 months of hard use.
Summary: I build computers on occasion- I use this ram in every build. It's reliable, priced well. I have never had a set of these fail on me. They run cool because they have their own heat sinks - which are nice anodized aluminium.
Summary: Didn't notice nearly as much of a performance increase as I would have expected when I doubled my RAM by adding 4 more gigabytes. But my machine is getting a bit older now so I guess that's life. Incidentally, did you know the proper pronunciation is "jigga bytes"? Look it up online, I was surprised too.
