Chapter 2: Installation
2-5
Gently press down on the memory module until it snaps into place.3.
With two CPUs installed, repeat step 2 to populate the CPU2 DIMM slots. 4.
Always install pairs of DIMMs to both CPU DIMM slots for more effi cient
operation.
Note: 256 MB, 512 MB, 1 GB, 2 GB, 4 GB and 8 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 H8DI3+/I+(-F) Serverboard.
Support
The H8DI3+/I+(-F) Serverboard supports single or dual-channel, DDR2-667/533/400
registered ECC SDRAM. Only interleaved memory is supported, so you must
populate two DIMM slots at a time (see procedure above).
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. Note: Due to a CPU limitation, fully populating DIMM slots with
DDR2-667 will pull the speed down to 533 MHz. Please see our web site for possible
updates to this limitation.
Maximum Memory
128 GB of DDR2-800/667/533 registered ECC SDRAM.

To Install:
Insert module vertically and press
down until it snaps into place.
The release tabs should close - if
they do not you should close them
yourself.
To Remove:
Use your thumbs to gently push
each release tab outward to re-
lease the DIMM from the slot.

Note the notch in the slot and on the bottom of the DIMM.
These prevent the DIMM from being installed incorrectly.
