5-4 Installing Memory
Caution
: Exercise extreme care when installing or removing DIMM modules to
prevent any possible damage.
The H8DGG-QF serverboard supports single/dual/tri/quad-channel, DDR3 Reg-
istered ECC DDR3-1333/1066/800 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.
Note : Check the Supermicro web site for recommended DIMMs.
Installing Memory Modules
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 5-4).
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 sup-
ported. 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.
Maximum Memory
Maximum memory for the H8DGG-QF serverboard is up to 512 GB of DDR3 Reg-
istered ECC or 128 GB of DDR3 Unbuffered ECC/non-ECC SDRAM.
