Comments about Corsair Memory Corsair Memory 4GB Twin 240DIMM DOMINATOR:
Corsair is a great brand and the design of this memory is likewise great. That said I must point to a potential problem with this memory. I have purchased two sets of this memory a month apart. Memory has never been overclocked, but it is rated to run at 1066 in the right system. The second set had a failure on one stick after less than a month or so in service. It was RMAd and the replacement memory still runs well after a year. The first set failed similarly after about a year in service, and again I RMAd it. I'm expecting delivery of replacement memory today from the factory. Corsair is very good about standing behind their products. I just wish they didn't have to do it so much.
Here's the deal: I did some research and have discovered that this memory type has more than it's share of failures. What sets it apart from other Corsair memory is the heatsink. Corsair uses quality parts, and the designs are well engineered, but like many companies these days I suspect they are chasing cheap manufacturing. That means there is a problem with the way it is made. I think the bonding process for the heat sinks may damage the chips just enough that the MTBF is lowered substantivly, but not so much that they can't be matched. Likely that the heat sink bonding uses a heat process to speed up manufacture time, and that the heat is not closly monitored by workers. Thermal conductivity works in both directions you know.
Bottom line: Corsair has changed the design of their Dominator line memory heatsinks. This is the older design. If you get a good set of this stuff it's like gold, works like a champ. Still, it's a roll of the dice. I purchased two sets and both failed. If I were you I'd look for the newer stuff. The heatsinks are modular on the new design, and I think it's likely Corsair has corrected the problem evident on the previous version.
