Memory

Memory is contained on small cards called DIMMs (dual inline memory modules). Each workstation enclosure can contain two, four, six, or eight DIMMs. The DIMMs are installed in eight slots located on the system node board.

These eight DIMM slots are organized into a group of even–numbered slots 0, 2, 4, and 6 and a group of odd-numbered slots 1, 3, 5, and 7, as shown in Figure 3-15.

DIMMs are installed one per slot, and two at a time, so that the two DIMMs installed provide local memory for the same pair of banks. For example, you can install a DIMM in slot 0 and another in slot 1 (this adds memory to bank pairs 0 and 1). Table 3-1 lists the DIMM slots and the corresponding bank pairs to which local memory is provided when DIMMs are installed:

Table 3-1. DIMMs and Bank Pairs

DIMM in Slot Number

5

4 and 5

6

6 and 7

7

6 and 7

[a] The first two DIMMs must be installed in DIMM slot 0 and DIMM slot 1.

When installing DIMMs, you must follow these rules:

  • Memory must be added and removed in two-DIMM increments only.

  • The two DIMMs that make up a bank pair must be the same memory size; however, each pair of DIMMs can be a different memory size from another pair.

  • The first two DIMMs must be installed in DIMM slot 0 and DIMM slot 1. Subsequent DIMM pairs can be installed in any order, but for consistency they should be installed in the next available DIMM slots.

  • The DIMMs used in the workstation are not compatible with the DIMMs used in Origin 200, SGI 2000 series, Onyx2, or Octane systems.
