Memory Configuration

The maximum amount of system memory the server supports is 384 MB of unbuffered memory, or 768 MB of registered memory.
To use registered DIMMs, you must remove all unbuffered DIMMs from the server.

The DIMMs that come with the server are unbuffered synchronous dynamic random-access memory (SDRAM) with error checking and correction (ECC). These memory modules have a speed of 100 MHz.



The below tables show some of the possible memory configurations for the server. Alternative configurations are possible.
