Does the 7DPXDW motherboard only support Registered DDR RAM? I use 1 x Unbuffered DDR DIMM in any DIMM Slot (4 Slots had been tested) but the speaker beeps 1 second and stop 3 seconds; then beep-warning sound is going on. Is the problem of DIMM? Or, the system BIOS only support Registered DDR?

GA-7DPXDW server board supports registered DDR memory only due to the hardware design issue. So far, our GA-7DPXDW CANNOT support un-buffered DDR memory. We may design a generation board, which can support un-buffered DDR memory in the future. Please refer to our Qualify Vendor List for the vendor of registered DDR memory.
