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.
