Installing And Removing Memory; About Memory - Silicon Graphics Octane2 Owner's Manual

Installing and Removing Memory

To install or remove memory, you must power off the workstation, wait 5 minutes to
allow the heat sinks to cool, and attach the wrist strap. Then remove the system module.
Follow the instructions for "Preparing the Workstation" on page 32 through, "Removing
the System Module." Then return to this page.
Caution: Dual inline memory modules (DIMMs) are extremely sensitive to static
electricity. Handle the DIMMs carefully and wear the wrist strap to avoid the flow of
static electricity.

About Memory

The Octane2 workstation has four DIMM banks with two DIMM sockets in each of the
banks. Before you install the two 1 GB DIMMs, review the following information:
• Bank 1 (sockets 1 and 2) must always be filled.
• The highest density DIMMs must be installed in Bank 1, while lower density
DIMMs must be installed in the remaining banks by order of their size (highest
density first).
• Banks must be filled sequentially; when Bank 1 is full, fill Bank 2. Do not skip banks.
• Each bank must be empty, or contain two DIMMs, one in each of the two sockets.
• Capacity refers to the number of megabytes or gigabytes of memory in a DIMM: 32,
64, 128, or 256 MB, and so on, or 1 GB.
– Minimum memory capacity is 64 MB (2 x 32 MB DIMM).
– Maximum memory capacity is 8 GB (8 x 1 GB DIMM).
– Minimum memory configuration is 64 MB in a bank (2 x 32 MB DIMM).
– Maximum configuration is 2 GB in a bank (2 x 1 GB DIMM).
