IBM IntelliStation M Pro User Manual page 53

Notes:
1. Any connector that does not have a RIMM installed must have a continuity
RIMM (C-RIMM), a module that looks like a RIMM but has no memory on it.
A C-RIMM is used to continue the connection on a RIMM connector that does
not have memory installed.
2. Install only ECC RIMMs to enable ECC. If you use ECC and non-ECC memory
together, it will function as non-ECC memory.
3. RIMM connectors do not support dual inline memory modules (DIMMs).
4. Use only PC600 or PC800 RIMMs.
Note: If you use PC600 and PC800 RIMMs together, all memory will function
at the speed of the slowest RIMM.
5. Your IntelliStation M Pro computer supports 128 MB, 256 MB, and 512 MB
RIMMs. Your computer supports a minimum of 128 MB and a maximum of 2.0
GB of system memory. Go to http://www.ibm.com/pc/support for a list of
memory modules to use with your computer.
Note: The illustrations in this document might differ slightly from your hardware.
Do the following to install a RIMM or C-RIMM:
