QuickSpecs
Memory
DDR SYNCH DRAM NON-ECC MEMORY
The Intel Pinetrail chipset supports non-ECC DDR2 PC2-6400 (800-MHz). Memory upgrades are accomplished by adding
single or dual DIMMs of the same or varied sizes. This chart does not represent all possible memory configurations.
CAUTION: You must shut down the computer and disconnect the power cord before adding or removing memory modules.
Regardless of the power-on state, voltage is always supplied to the memory modules as long as the computer is plugged in
to an active AC outlet. Adding or removing memory modules while voltage is present may cause irreparable damage to the
memory modules or system board.
HP recommends dual-channel symmetric configurations for maximum performance.
For best performance, add the same amount of total memory to each channel and do not mix speeds. For dual-channel
symmetric performance, the total amount of memory in each channel must be equal. If speeds are mixed, speed will default
to the slowest DIMM.
STANDARD MEMORY
1-GB, 2-GB, 3-GB or 4-GB DDR2 SYNCH DRAM
OPTIONAL MEMORY UPGRADES
Supports up to 4 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.
