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.
Microtower and Small Form Factor
Maximum Memory
Supports up to 8 GB of DDR2 Synch DRAM.
Not all memory configurations possible are represented below.
NOTE:
For systems configured with more than 3 GB of memory and a 32-bit operating system, all memory
may not be available due to system resource requirements. Addressing memory above 4 GB requires a 64-
bit operating system.
