Hello jfwalter,   I sorry I missed that part about the memory buffer and that is on the CPU board.   You should be ok to use V2 CPU board: M9DGR
Hi guys, Some years ago I upgraded the BIOS & CPLD of my R810 and installed four Xeon E7-4870. The R810 is the first revision and does not have the Roman II near the S/T. Now I would like to install 32Gb RDIMM to go from 512Gb to 1Tb memory. Is it possible to change only the CPU/RAM system board to a new one with Intel 7510 memory controller? I think I have a R810 V1 System Board: 0FDG2M and need a V2:  0M9DGR. Thanks, Jean-François
