Installing Memory
Caution: Exercise extreme care when installing or removing DIMM modules to prevent any
possible damage.
SGI Rackable C2108-TY11 serverboard supports up to 288 GB of DDR3 1333/1066/800
registered ECC SDRAM in 18 DIMM slots. Three-way interleaved memory is supported. For
optimal memory performance, install DIMMs three at a time. Use memory modules of the same
type and speed. See the following table for memory installation.
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 alignnment notch at the bottom of the module to avoid installing incorrectly
(see Figure 5-3 and 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
Table 5-1). Always spread DIMMs across all three banks for each CPU (see Figure 5-2).
Gently press down on the DIMM module until it snaps into place in the slot. Repeat for all
modules.
2. To remove a DIMM module, use your thumbs to gently push the release tabs near both ends
of the module (see Figure 5-3). This should release it from the slot (see Figure 5-5).
