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 H8DGU-LN4F+ serverboard.
Memory Support
The H8DGU-LN4F+ serverboard supports single/dual/tri/quad-channel DIMMs with
DDR3-1600/1333/1066 Mhz speed 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-LN4F+ serverboard supports up to128 GB of ECC/Non-ECC
Unbuffered or 768 GB of ECC Registered DIMM in 24 DIMM slots.
