which board? i have an asus p9x79 deluxe and it does support rdimm up to 8gb. i have 2 two of the chinese x79 boards and they both support 16gb rdimm.Thinking about ordering the PlexHD. It seems that most of these X79 motherboard don't actually support RDIMM, only UDIMM even though they claim "ECC" support. This listing specifically states "REG ECC" memory.
Anyone want to take a guess or have any information as to whether this is true?
I have a ton of DDR ECC RDIMM but very few UDIMM and don't relish paying the price for more UDIMMs...
if you are going to run i7 like i7-3930k, you need to have udimm. some boards like supermicro x9sra seems to let you get away with udimm ecc, but asus p9x79 wont work with ecc udimm for i7..
