For the SC815TQ-R650U chassis and X8DTU motherboard (to be used for PCI-X expansion), is the R1UU-AXE8 riser card compatible with X8DTU? Can I put a full-height, full-length card in both the PCI-X slot and PCIe x8 slots? Also, can the R1UU-E8PR be used on the right side?
R1UU-AXE8 is compatible with X8DTU motherboard and 815TQ-R650 chassis. The PCB revision of R1UU-AXE8 must be revision 2.0 to support X8DTU.
Full-length PCI-X and PCI-e cards can be installed but you must make sure that the width of the card is suitable.
R1UU-E8PR can be used in right side, but it is only for low-profile small cards like the AOC-PG-i2+ LAN card, for your reference.
