Processor/Memory Subsystem
Table 3-1 shows suggested memory configurations for these systems. Note that the USDT form factor provides only three DIMM sockets and therefore cannot match the SFF, ST, MT, and CMT form factors in maximum memory capacity.
NOTE: Table 3-1 does not list all possible configurations. Balanced-capacity, dual-channel loading yields best performance.
