There is an unconfirmed rumor that Corsair will stop using Elpida in their High-end dominator RAM.
According to a forum post on the Corsair help pages Corsair has been seeing a higher than normal failure rate of Dominator RAM with Elpida Hyper based modules.
This has lead to a recall of more than a few Corsair products. The TW3X4G1600C6GTF, TR3X6G1866C7GTF, TR3X6G2000C8GTF, TR3X3G2000C7GTF, and TR3X6G2000C7GTF are all listed as affected.
If you have one of these kits and are having trouble you might want to head over to their warranty page and see what they can do for you.
Although there has been no "official" announcement from Corsair on this other than the Forum page, it is very nice to see a manufacturer like Corsair standing behind their products even though the flaw is not their direct fault.
