Installing A Dimm - Silicon Graphics SGI 1100 Maintenance And Upgrade Manual

Installing a DIMM

007-4047-001
The four 168-pin DIMM sockets in the SGI 1100 server support SDRAM-type DIMMs.
You may install 128-MB or 512-MB (single density) DIMMs for a maximum of 2 GB of
system memory. (the system will also support 1-GB DIMMs, when available, for a
maximum of 4 GB of system memory).
Caution: Only 3.3-volt PC-133 SDRAM DIMMs should be used. The SGI 1100 server
system does not support 5-volt memory devices, nor does it support PC-100 or PC-66
SDRAM DIMMs. For a list of qualified vendors, contact your reseller.
Each of the DIMM sockets is independent from the others. This independence allows you
to install DIMMs with different capacities to form different configurations.
Follow these steps to install a DIMM:
1. Remove the chassis cover as described in "Removing the Chassis Cover" on
page 21.
2. Align the DIMM in an empty slot and press it in until the retaining clips secure the
DIMM in place, as shown in Figure 2-53.
Caution: The DIMM closest to the processors (DIMM 1) may touch the processor fan
cages during the installation of the DIMM. Proceed carefully, do not apply excessive
lateral pressure on the DIMM socket.
