If you own a set of ultra-high spec DDR3 RAM, then chances are high that your RAM uses Elpida "Hyper" integrated circuits. Amid concerns of higher than average failures of both Corsair RAM and memory from other vendors, Corsair has withdrawn all Hyper-based modules from sale.
Here's the official statement:
We have seen a number of reports across various forums about failures of modules (from Corsair as well as from other memory manufacturers) built with Elpida "Hyper" RAMs. Through lab testing, we have now been able to reproduce similar failures. We are continuing to test to determine the cause of these failures. Note that although a relatively small percentage of "Hyper" ICs appear to be affected, the rate of failure is not acceptable to Corsair or to our customers.
Due to these failures, we will no longer sell Hyper-based modules until the issue can be resolved. We have also have asked our retailers to return any modules they currently have on their shelves. Products impacted include TW3X4G1600C6GTF, TR3X6G1866C7GTF, TR3X6G2000C8GTF, TR3X3G2000C7GTF, and TR3X6G2000C7GTF. We are working on enhancing our manufacturing and testing process to be able to offer these parts again as soon as possible.
We continue to stand behind these modules 100% with our standard warranty, which can be found at http://www.corsair.com/warranty/default.aspx.
If you own any of this RAM, keep an eye out for future failures.
