Hardware Installation

Warning:

Electrostatic discharge (ESD) can damage your system board, processor, disk drives, add-in boards, and other components. Perform the upgrade instruction procedures described at an ESD workstation only. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, establish and maintain contact with the system chassis throughout any procedures requiring ESD protection.

2.2 System Memory

The two 184-pin SRIMM sockets on the system board uses RIMMTM modules for memory expansion. A RIMMTM module may come with 4, 8, 12, 16 or more devices. A device refers to 1 RDRAM chip. In other words, a module with 8 devices means the module has 8 RDRAM (Rambus Dynamic RAM) chips on it. A device provides 1.6GB/sec bandwidth which is several times the bandwidth available from a SDRAM. An example of a RIMMTM module with 8 devices is shown below.

When you purchase a RIMMTM module, the devices on the module are not visible unlike the one shown above. This is because the module has already been packaged with a heatsink. Make sure you know the number of devices and the RDRAM technology used when you purchase the module because these information are important when you configure your system memory. Please read the following sections carefully.
