Figure 6-9 32-DIMM Memory Extender Board Slot IDs You can insert additional DIMMs into both 16- and 32- DIMM boards. When adding DIMMs, you must use a minimum of four like sized DIMMs in the next available quad. Supported DIMM Sizes You can install up to 128 GB of memory in the server. Supported DIMM sizes are as follows: • 256 MB, 512 MB, 1 GB, 2 GB, 4 GB Dissimilar DIMM sizes can be used across the extender board, but all four DIMMs in each quad must match. For cooling purposes, DIMM slot fillers must be used in some unused connectors. DIMM Slot Fillers Both the 16- and 32-DIMM extender boards have DIMM slot filler boards placed over all unfilled DIMM connectors. As you fill DIMM quads with additional memory you must remove the DIMM slot fillers covering the affected connectors. To maximize internal cooling, all remaining DIMM fillers in unused connectors must remain in place (Table 6-1). NOTE: One DIMM filler board covers two adjacent DIMM connectors. Remove DIMM slot fillers as you add memory and the correct configuration will always remain. Installing DIMMs To install DIMMs, follow these steps: System Memory DIMMs 159

Figure 6-9 32-DIMM Memory Extender Board Slot IDs
You can insert additional DIMMs into both 16- and 32- DIMM boards. When adding DIMMs,
you must use a minimum of four like sized DIMMs in the next available quad.
Supported DIMM Sizes
You can install up to 128 GB of memory in the server. Supported DIMM sizes are as follows:
•
256 MB, 512 MB, 1 GB, 2 GB, 4 GB
Dissimilar DIMM sizes can be used across the extender board, but all four DIMMs in each quad
must match. For cooling purposes, DIMM slot fillers must be used in some unused connectors.
DIMM Slot Fillers
Both the 16- and 32-DIMM extender boards have DIMM slot filler boards placed over all unfilled
DIMM connectors. As you fill DIMM quads with additional memory you must remove the DIMM
slot fillers covering the affected connectors. To maximize internal cooling, all remaining DIMM
fillers in unused connectors must remain in place (
Table 6-1
).
NOTE:
One DIMM filler board covers two adjacent DIMM connectors. Remove DIMM slot
fillers as you add memory and the correct configuration will always remain.
Installing DIMMs
To install DIMMs, follow these steps:
