Installing Memory
1. Insert each memory module vertically into its slot, paying attention to the
notch along the bottom of the module to prevent inserting the module
incorrectly (see Figure 2-1).
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 CPUs installed, repeat step 2 to populate the CPU2 DIMM slots.
Always install four DIMMs to both CPU DIMM slots for more efficient
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 H8DG6-F serverboard.
Memory Support
The H8DG6-F serverboard supports single/dual/tri/quad channel,
DDR3-1600/1333/1066 Mhz speed 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 H8DG6-F serverboard supports a maximum of up to 128 GB of ECC/Non-ECC
UDIMM or 512 GB of ECC RDIMM in sixteen (16) DIMM slots.
CAUTION! Exercise extreme care when installing or removing DIMM modules to
prevent any possible damage.
