Platform Notes: SPARCstation 10SX and SPARCstation 20 System Configuration Guide

Advantages of Using SXDRAM

As a configuration option, you can reserve SXDRAM. When SXDRAM is reserved, the SX has additional optimizations available to it when accessing SXDRAM, and operations on SXDRAM execute more quickly. The reserved memory, however, is then not available for use by other applications. For example, on a 48-megabyte system, allocating 16 megabytes of SXDRAM means that the system will in effect run as a 32-megabyte system.
