2. Install to slots CPU1/DIMM1A, CPU1/DIMM2A, CPU1/DIMM3A and CPU1/
DIMM4A, etc. Always install in groups of four and in the numerical order of
the DIMM slots. See support information below.
3. Gently press down on the memory module until it snaps into place.
4. With four DIMMs installed, repeat step 2 to populate the CPU2 DIMM
slots. Always install four DIMMs to both CPU DIMM slots for more effi cient
operation.
Note: 1 GB, 2 GB, 4 GB, 8 GB, 16 GB or 32 GB size memory modules are
supported. It is highly recommended that you remove the power cord from the
system before installing or changing memory modules. Please refer to our web site
for memory that has been tested on the H8DGG-QF serverboard.
Support
The H8DGG-QF serverboard supports single/dual/tri/quad-channel, DDR3
Registered ECC DDR3-1600/1333/1066 Mhz or DDR3 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
Maximum memory for the H8DGG-QF serverboard is up to 512 GB of DDR3
Registered ECC or 128 GB of DDR3 Unbuffered ECC/non-ECC SDRAM.
To Install: Insert module
vertically and press down
until it snaps into place.
