Hardware Installation

For example, if a module that uses the 64Mbit/72Mbit technology

has 8 devices - then the memory size of a device multiplied by the

number of devices will be the total memory size of the module.

Memory Size of a Device

8MB

16MB
32MB

RDRAM Technology

64Mbit/72Mbit

128Mbit/144Mbit
256Mbit/288Mbit

8MB

(memory size of

1 device in a

64Mbit/72Mbit

technology)

(8 devices on the

module)

64MB

(memory size of

the module)

2.2.1 Determining the Memory Size of a RIMM

Module

The memory size of a RIMM

module will depend on the memory

size of a device and the number of devices used; and the memory

size of a device will depend on the RDRAM technology used.

2.2.3 Important Installation Instructions

Important:

Certain rules must be followed when installing RIMM

modules to obtain optimum system performance.

Rule 1. The RIMM

module with the most devices must be

installed into the RIMM1 socket.

Mem. Size of a Device x 32 Devices = Max. Memory

8MB x 32 = 256MB

16MB x 32 = 512MB

32MB x 32 = 1GB

RDRAM Technology

64Mbit/72Mbit

128Mbit/144Mbit
256Mbit/288Mbit

2.2.2 Determining the Maximum System Memory Size

The maximum memory size supported by the system will depend

on the memory size of a device (relevant to its RDRAM technology)

multiplied by 32. Why 32? This is because a system has only 1

Rambus Channel and a Rambus Channel supports up to 32 devices

only.
