Memory support
The H8DMT+/H8DMT-INF+ has sixteen 240-pin DIMM sockets that can support up
to 64 GB of single or dual channel DDR2-667/533/400 registered ECC SDRAM (for
a total of 128 GB in the system).
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 incor-
rectly (see Figure 2-1).
2.
Install to slots CPU1/DIMM1A and CPU1/DIMM1B fi rst, 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 effi cient
