I mistakenly bought some of these a while ago for my Supermicro C2000 based ITX boards before I could find specs assuming they were unbuffered, but they turned out to be ECC Reg. Does anyone know what uses these? I tried them in a couple of theoretically compatible boards through SODIMM -> DIMM adapters a while ago (I forget who suggested the adapters, but thanks!) unfortunately with no luck, but the adapters were cheap and maybe they don't support ECC Reg, or maybe the board doesn't like the timings on this RAM. Anyway, I have 5 of them (I think I was going for a 64GB set plus a spare), and they are marked: Micron MT36KSS2G72RHZ-1G6E1HE 16GB 4Rx8 (plus date codes, which look like the end of 2014 to me) Someone on ebay is selling them for 100 each, which seems ridiculous (I think that's a bit more than I paid) but they have sold some, and all I can find quickly googling is places selling them for even more, but no mention of what uses them - any ideas?
