Removing and Installing Memory

The server board supports only PC133-compliant SDRAM. Install from 128 MB to 6 GB of registered memory, using up to six single- or double-banked DIMMs.

DIMMs must be installed in pairs in the following order: 1A-1B, 2A-2B, and 3A-3B as shown in Figure 16. The DIMM sockets are further identified on the board’s silkscreen.

Installed DIMMs must be the same speed and must all be registered. For a list of supported memory, call your service representative or visit the IBM Support website.
