Comments:

MODULES MAY BE INSTALLED ONE AT A TIME; however, they must be added in like pairs to take advantage of dual-channel support.
If 4GB is installed, the recognized memory may be reduced to 3.5GB or less (depending on system configuration and memory allocation).
Maximum configurations require a 64-bit operating system.
Per HP documentation, system supports DDR3-1333 PC3-10600 memory which may run at slower speed depending on system configuration.
