A+ SERVER 2022G-URF User's Manual

Memory Support

The H8DGU(-F) serverboard supports single/dual/tri/quad-channel, DDR3-1600/1333/1066 Mhz registered ECC/Unbuffered ECC/non-ECC SDRAM.

Populating four adjacent slots at a time with memory modules of the same size and type will result in interleaved (128-bit) memory, which is faster than non-interleaved (64-bit) memory.

Maximum Memory

The H8DGU(-F) serverboard supports up to 128 GB of ECC/Non-ECC Unbuffered, 512 GB of Low-profile ECC Registered LRDIMM, or 512 GB of ECC Registered DIMM SDRAM in sixteen (16) slots.
