H8SCM(-F) SERVERBOARD USER'S MANUAL
2-8
Memory Support
The H8SCM(-F) serverboard supports single and dual channel,
DDR3-1600/1333/1066 Mhz speed registered ECC/Unbuffered ECC/non-ECC
SDRAM. Only interleaved memory is supported, so you must populate two DIMM
slots at a time, one per channel (see procedure above).
Populating two 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 H8SCM(-F) serverboard supports up to 32 GB of ECC/Non-ECC UDIMM or up
to 128 GB of ECC RDIMM in four (4) DIMM slots.
Memory Population for Optimal Performance
# DIMMS Channel 1 Channel 2
2 DIMMs DIMM1A DIMM2A
4 DIMMs DIMM1A DIMM1B DIMM2A DIMM2B
Note: Memory speed support is dependent on the type of CPU used on the board.
Figure 2-1. Installing DIMM into Slot
