2.5System memory

2.5.1 Overview

This motherboard has two 232-pin Rambus Inline Memory Modules (RIMM) sockets. These sockets support 32-bit RIMMs in the following sizes: 128, 256 and 512Mbit RDRAM RIMMs.

C-RIMMs (Continuity RIMM) must be used to complete the socket that is not populated by RDRAMs. To assure the electrical integrity of the Rambus interface. A C-RIMM is necessary to avoid breaking the signal lines, which are a serial connection in a Rambus interface.

The diagram below shows the various combinations for inserting RIMMs.)
