Memory Modules - IBM RS/6000 7046 Service Manual

Memory Modules

You can increase the amount of memory in your system by installing memory
modules. Your server uses 168-pin, 3.3 volt, dual inline Error Correcting Code
(ECC) memory modules (DIMMs) to increase system memory.
You install memory modules into connectors inside the server. You can install up to
1024MB of ECC memory. (1MB equals approximately 1 000 000 bytes.) The
memory module sizes for your system include 256MB, 128MB, 64MB, 32MB, and
16MB. The available speed for these memory modules is 60 ns.
Note: When you install memory modules, install the new modules into the first
available unused connector, starting at slot 4.
Removing Memory Modules
1. Locate the memory module connectors on the system board.
The memory module connectors are shown in the following figure.
2. Remove any adapters that are blocking the memory module connectors (see
"Adapter" on page 7-25).
3. Determine which memory modules you want to remove.
If you are replacing the memory modules you remove, they must be replaced
with the same type.
