  We have tried to make it work to the best of our ability and it is not working. It appears that the 2 CPU requirement is not merely a suggestion. It appears to be a hard requirement that will limit functionality. Thanks
I have an R730 with PCI Risers 2 and 3 installed, with the goal of using it as a GPU server. Our supported card, AMD FirePro S9150, doesn't show up at all in Lifecycle Controller or in OS (using lspci, Centos 6). In BIOS, the 6 slots listed under "slot disablement" are also listed as enabled (assuming these refer to PCI slots anyway, and that if they say "enabled" it doesn't mean "disablement is enabled" and thus they're actually disabled?) Dell support believes I need a 2nd CPU in the system for the riser 2 & 3 pci slots to be usable. That seems to be based on this part of the R730 Owner's Manual: GPU card installation guidelines• Ensure that both the processors are installed.• The processor must be of 135 W or less.• The processor must use a GPU kit low-profile heat sink. But I thought I'd find out if anyone knows for sure, b/c the above working is a little ambiguous. The first requirement says "both processors", but the next two are singular. Thanks -Michael
R730 needs 2 CPU's to use PCI slots for GPU?
