Software installation procedures are described in Chapter 4. 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.

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
