Appendix A – DRAM Installation
The XVME-655 has two 72-pin in-line memory module (SIMM) sites in which to add
memory. Due to the CPU speed, DRAM access time should be 70 ns or less, and must be
60 ns to run with zero wait states. Both SIMMs must be populated to provide a 64-bit
memory interface.
The XVME-655 can accommodate 8, 16, 32, or 64 Mbytes of DRAM. You can use 1M x
32, 2M x 32, 4M x 32, or 8M x 32 DRAM SIMM sizes. Table Appendix A-1 lists the
combinations needed for the four memory configurations. (The "U" number is silk
screened on the front of the board).
Recommended manufacturers for DRAM, along with the respective part numbers, are
listed below.
