DDR2 SYNCH DRAM NON-ECC MEMORY
Memory upgrades are accomplished by adding single or multiple DIMMs of the same or varied
sizes. This chart does not represent all possible memory configurations. Memory DIMMS must be
populated beginning with DIMM slot 4 (Channel B) or DIMM slot 3 (Channel A). Slot 4 must be
populated before slot 2, and slot 3 must be populated before slot 1.
HP recommends dual-channel configurations for maximum performance.
For best performance, place matching DIMMs in black memory slots 4 and 3 (and in white
memory slots 2 and 1 if used). Matching DIMMs have the same size, speed, and number of
memory chips. If the slot pairs are not matched, all the memory is still used, but the system will
operate in single-channel mode. If speeds are mixed, speed will default to the slowest DIMM.
