Memory

PC2-5300E DDR2-667 ECC Unbuffered or PC2-6400E DDR2-800 ECC Unbuffered RAM DIMMs
Only Error Checking and Correcting unbuffered DDR2 DIMMs are supported and must be either x8 or x16 width. Memory
upgrades are accomplished by adding DIMMs of the same or varied sizes. The Intel chipset supports both PC2-5300 DDR2-
667 and the PC2-6400E DDR2-800 ECC unbuffered memory. It is suggested to not mix ECC and non-ECC memory.
For best performance the total amount and type of memory loaded into Channel A and Channel B should be the same. If it is
not, your computer will see all the RAM installed but will run the memory controller at a lower performance mode. Although
not required, for best performance add the memory in pairs rather than as a single DIMM (two 512 MB DIMMs will have
better performance than a single 1 GB DIMM). Also, add the memory into both channels (e.g. one in socket 1 and one in
socket 3) to take advantage of dual channel performance. If you have unused slots within a channel, make them socket 2
and socket 4. This provides the best margin for the memory bus. If you are only using 1 DIMM, install it in socket 1.
MAXIMUM MEMORY
Supports up to 8 GB DDR2-667 or DDR2-800 ECC unbuffered memory
POSSIBLE MEMORY CONFIGURATIONS
Not all memory configurations possible are represented below. Please install memory in pairs. Configurations using three
DIMMs are not supported by HP.
