modules to prevent any possible damage.
Memory Support
The H8DGG-QF serverboard supports single/dual/tri/quad-channel, Registered
ECC DDR3-1333/1066/800 or DDR3 Unbuffered ECC/non-ECC SDRAM. Only
interleaved memory is supported, so you must populate four DIMM slots at a time
(see procedure above).
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 effi cient
operation.
Note: 1 GB, 2 GB, 4 GB, 8 GB and 16 GB 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.
Maximum Memory
Maximum memory for the H8DGG-QF serverboard is up to 256GB of Registered ECC
DDR3-1333/1066/800 or 64GB of DDR3 Unbuffered ECC/non-ECC SDRAM.
