Well that was a missed false start on UNC . <| sep |> i hope not but since usCANADA <| sep |> I didn ' t say he was offended . Just because he didn ' t take offense at an insult does not mean he wasn ' t insulted . <| sep |> only thing you can do is try the UDIMMs and see if they work . The thing is , is that DDR 3 8 gb ECC UDIMMs are twice or more the price of 8 gb ECC RDIMMs , sometimes running $ 30 or more each . Why not just get some 8 GB ECC RDIMMs for around $ 10 each , and then upgrade them as 16 gb RDIMMs become available ? Also , you get better prices if you buy in lots . Lots of 4 x 16 gb ECC RDIMMsDDR 3 will probably run you around $ 150 , wherease individual 16 GB ECC RDIMMs will be around $ 5075 each . On a side note , if you have 8 GB 2 Rx 8 DDR 3 UDIMMs that you want to sell , I can offer $ 25 each for them .
