Installing Memory
Caution: Exercise extreme care when installing or removing DIMM modules to prevent any
possible damage.
The C2112-4G3 serverboard supports up to 16 DIMM slots. Three-way interleaved memory is
supported. For optimal memory performance always use memory modules of the same type and
speed. See also
Table 5-1 on page 35 and Table 5-2 on page 37 for memory installation guidelines.
Install DIMMs
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 on page 34 ). 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
Table 5-1 on page 35 for DIMM placement with single-CPU serverboards). Always spread
DIMMs across all applicable banks for each CPU. Gently press down on the DIMM module
until it snaps into place in the slot. Repeat for all modules.
2. When working with a dual-CPU serverboard and 8 or 16 DIMMs, install in 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
Table 5-2 on
page 37 for DIMM support configuration information.
3. Gently press down on the memory module until it snaps into place.
4. Repeat the installation steps to populate each of the applicable CPU DIMM slots. See
Table 5-2 on page 37 for dual-CPU applications on a serverboard.
For the most efficient operation, always install an even number and equal amount of DIMMs to
support each CPU.
Note: 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.
