slots labeled DIMM 0A and DIMM 0B. Load the second matched pair in Memory
Cell 1 and in the slots labeled DIMM 1A and DIMM 1B. Continue loading
successive matched pairs using the sequence described in Figure 2-15. To achieve
optimal system performance, always load memory in the sequence described in
Figure 2-15. To ensure “chip spare functionality,” memory must be loaded in quads
(two pairs). Refer to the section “Chip Spare Functionality (rx2600 systems only)” in
the Appendix B for more information.
