Upgrading Memory

The memory for the HP x4000 Workstation is located on a Memory

Expander Card, which plugs into the system board.

There are two memory banks (RDRAM channels):

• Bank I includes sockets 1B (J1), 2B (J2), 1A (J5), and 2A (J6).

• Bank II includes sockets 3B (J3), 4B (J4), 3A (J7), and 4A (J8).

This allows for a total of 8 RIMMs.

You must adhere to the following rules when loading memory:

• RIMMs must be loaded in matched pairs. Matching RIMMs have the

same RDRAM size, speed and Mbit technology.

• Each RDRAM bank (channel) must be either completely empty or

completely filled as shown in Figure 1-2. Therefore, if only one pair of

RIMMs is installed in a bank, then the remaining sockets in the bank

must contain continuity modules (CRIMMs) to ensure continuity.

All Workstations (unless they already have 8 RIMMs) ship with a pair of

CRIMMs in case they are needed in future memory configurations.
