Install DIMMs

007-5683-004
Caution: Exercise extreme care when installing or removing DIMM modules to prevent any
possible damage.
The H2106-G7 serverboard supports up to 32 DIMM slots. Three-way interleaved memory is
supported. For optimal memory performance always use memory modules of the same type and
speed. See the following table for memory installation.
Perform the following steps to install memory modules, as follows:
1. Insert the DIMM module vertically and press down into its slot until it snaps into place. Pay
attention to the alignment notch at the bottom of the module to avoid installing incorrectly
(see Figure 5-4). Insert the desired number of DIMMs into the memory slots, beginning with
DIMM #1A and DIMM #2A, then DIMM #3A and DIMM #4A, etc. (see
page 38 for 16-DIMM placement). Always spread DIMMs across all banks for each CPU.
Gently press down on the DIMM module until it snaps into place in the slot. Repeat for all
modules.
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 each of the four CPU DIMM slots. See
Table 5-2 on page 39
For the most efficient operation, always install four or eight DIMMs to support each CPU.
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. Check with your sales or service representative for memory that has been tested
and approved for the serverboard.
