Think that we wonīt get Hyper back from RMAs from most of the Dram houses is a fact we have to accept as the ICs are EOL and therefore hard to get, even for the manufacturers- was the same with D9s at DDR2, I was lucky to get D9s back at two RMAs(ebay buys that were defect) but at the other rmas I made for friends I got other ICs, performing worse- but always were the best the manufacturers could offer as replacement
