  • 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.
  • Systems based on Intel GL40 chipset supports up to 4GB maximum.
  • Per HP documentation, system supports DDR3-1333 (PC3-10600) and 1066 (PC3-8500) modules but memory Bus may run at 1066MHz (PC3-8500 MB/sec) depending on processor
