Introduction

Cache Memory Module

Adaptec cache memory modules provide up to 256 MB of high-

speed SDRAM disk cache with ECC (Error Correction Coding).

Note: Adaptec RAID controllers that use installable memory

modules will not function without a module available. The

on-board processor uses some of the available memory. Do

not be alarmed if an Adaptec utility application reports less

memory available for caching than you have installed.

When ECC memory is installed, the green ECC Enabled (ECCEN)

LED is lit. (Non-ECC memory could work in your controller, but is

not recommended.) Refer to Appendix A for the location of the LED.

Visit

www.adaptec.com for a list of memory that has been approved

by Adaptec. Memory requirements are described in the following

table:

Controller

Memory

Sockets

Capacities (MB) Type

Adaptec 2000S None

ECC SDRAM - not user

expandable

Adaptec 2005S None

Adaptec 2110S None

Adaptec 2400A 1

32, 64, or 128

3.3-V, 100-MHz (or faster)

During normal operation, Socket 1 (designator J1) must always contain a memory

module. Refer to Appendix A, Card and Module Diagrams to verify the location of

Socket 1. When two sockets are in use, the modules must match each other in type and

capacity.
