Problem Description

A portion of the interleaved and non-interleaved memory configuration
tables shown in the Celebris XL Pentium Pro User's Guide is incorrect.

TechTip Summary

Solution

Use the memory tables below for proper configuration.

Detailed Implementation Procedure

Non-Interleaved
For non-interleaved mode, install SIMMs in pairs, one pair in each
Bank of Interleave 0, starting with Bank 0.

     SIMM pairs must be the same type, size, and speed. You cannot
     mix SIMM sizes within pairs.

     SIMMs can have either 60 or 70 ns access time. The system
     automatically detects the access time of the SIMMs.

The table below shows the recommended memory upgrade paths.  For non-
interleaved mode, upgrade your system memory in pairs, by installing
two SIMMs of equal capacity per the following chart. Only Interleave
0 can be used for Non-Interleaved mode.
