When installing system memory, refer to the following illustration for the location of the memory connectors, the power connector, and the hard disk fan connector on the memory card with four RIMM connectors. A B C D 1 RIMM pair 1 2 RIMM pair 2 3 Power connector 4 Hard disk drive fan connector A RIMM connector 1 B RIMM connector 2 C RIMM connector 3 D RIMM connector 4 Working with memory You can add memory to your computer to increase system performance. Your computer has up to eight connectors for installing Rambus inline memory modules (RIMMs). The IBM-installed RIMMs that come with your computer are ECC (error checking and correction) RDRAM (Rambus dynamic random access memory) modules. When installing or replacing RIMMs, take the following information into consideration: The memory card your computer has four or eight RIMM connectors arranged in pairs. RIMMs must be installed in pairs. The RIMMs installed in a RIMM connector pair must be the same speed and size. If the memory card in your computer has four RIMM connectors, 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 in it. 64 IntelliStation Z Pro User Guide
