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.
