Installing Memory
Caution! Exercise extreme care when installing or removing DIMM modules to
prevent any possible damage.
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 and CPU1/DIMM1B first, then to CPU1/
DIMM2A and CPU1/DIMM2B, etc. Always install in pairs 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 two CPUs installed, repeat step 2 to populate the CPU2 DIMM slots.
Always install pairs of DIMMs to both CPU DIMM slots for more efficient
operation.
Note: Sixteen (16) 1GB, 2GB, 4GB, 8GB, 16GB or 32GB 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 H8DGT-HIBQF/HF serverboard.
Support
The H8DGT-HIBQF/HF serverboard supports single/dual/tri/quad-channel,
DDR3-1600/1333/1066 MHz speed registered ECC/Unbuffered ECC/non-ECC
SDRAM.
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
Maximum memory for the H8DGT-HIBQF/HF serverboard is 512 GB of registered
ECC or 128 GB of DDR3 Unbuffered ECC/non-ECC SDRAM.
