Memory DIMMs

The workstation is available with 1, 2, or 4 R16000 MIPS processors. These processors are
available in several different clock speeds. Each processor has a total of 64 KB onboard
cache memory and 4-MB of external cache memory. The processors are mounted on the
system node board under a protective cover.
The workstation is configured with a minimum of 512 MB of memory and a maximum
of 8 GB of memory. Your system uses double data rate synchronous dynamic
random-access memory (DDR SDRAM). The DIMMs used in your workstation are
compatible with the DIMMs used in Origin 300, Origin 3000, and Onyx 3000 systems.
The DIMMs used in your workstation are not compatible with the DIMMs used in
Octane, Octane2, O2, O2+, Origin 200, Origin 2000, or Onyx2 systems.
The memory DIMMS are installed in eight DIMM slots on the system node board. The
DIMM slots are numbered 0 through 7 (see Figure 2-4). The slots are grouped into four
pairs of two DIMMs. The DIMM pairs are numbered as follows:
• DIMM pair 1: slots 0 and 1
• DIMM pair 2: slots 2 and 3
• DIMM pair 3: slots 4 and 5
• DIMM pair 4: slots 6 and 7
