2.6 DSIMMs and NVSIMMs
Three SIMM options exist; two are DRAM SIMMs. (Refer to Figure 2-13.) The
third is a nonvolatile SIMM (NVSIMM). (Refer to Figure 2-14.) All three SIMM
types are removed and replaced in the same manner. Table 2-1 summarizes the
SIMM variations.
Note – These SIMMs were designed for the SPARCserver 1000 system and are
not interchangeable with other types of SIMMs.
Type A 8 Mbyte SIMMs are interchangeable with Type B 8 Mbyte SIMMs. The
two 32 Mbyte SIMM types many also be interchanged. However, SIMMs of
different capacities cannot be interchanged within a group. To select the proper
socket locations for the SIMMs, refer to Appendix A, “Configuring SIMMs and
Jumpers.”
