Maximum Memory

The H8SGL-F motherboard supports up to 256 GB of registered ECC or 64 GB of unbuffered ECC/non-ECC SDRAM in eight (8) DIMM slots.

Memory Population for Optimal Performance

-For a Motherboard with One CPU (CPU1) Installed

# DIMMS	CPU	Channel 1		Channel 2		Channel 3		Channel 4
4 DIMMs	CPU1	P1-1A		P1-2A		P1-3A		P1-4A
8 DIMMs	CPU1	P1-1A	P1-1B	P1-2A	P1-2B	P1-3A	P1-3B	P1-4A	P1-4B

Note: Memory speed support is dependent on the type of CPU used on the board.
