Adaptec RAID Installation Guide Cache Memory Module Adaptec cache memory modules provide up to 256 MB of highspeed SDRAM disk cache with ECC (Error Correction Coding). Note: You must have at least 32 MB of cache installed. The on-board processor uses 16 MB of the available memory. Therefore, the RAID software shows 16 MB less than is actually 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. You can use non-Adaptec memory from qualified third-party vendors. Visit www.adaptec.com for a list of memory types and manufacturers that have been approved by Adaptec. Requirements for non-Adaptec memory are described in the following table: Controller Sockets Available Capacities (MB) Type Adaptec 2400A Adaptec 2100S Adaptec 3210S Adaptec 3410S Adaptec 3200S/ 3400S 1 32 (as shipped), 3.3-V, 100-MHz (or faster) 1 64, or 128 PC100-compliant, 168-pin ECC DIMM (Dual 1 32, 64, 128, or In-line Memory Module). 256 1 64 (as shipped), 128, or 256 21 32 (as shipped), 100-MHz SDRAM, 64, or 128 144-pin SODIMM.

Adaptec RAID Installation Guide
Cache Memory Module
Adaptec cache memory modules provide up to 256 MB of high-
speed SDRAM disk cache with ECC (Error Correction Coding).
Note:
You must have at least 32 MB of cache installed. The
on-board processor uses 16 MB of the available memory.
Therefore, the RAID software shows 16 MB less than is
actually 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.
You can use non-Adaptec memory from qualified third-party
vendors. Visit
www.adaptec.com
for a list of memory types and
manufacturers that have been approved by Adaptec. Requirements
for non-Adaptec memory are described in the following table:
