MEMORY
Standard
DDR3L SDRAM (1600 MHz)
Two SODIMM slots supporting dual-channel memory
2 GB, 4 GB, and 8 GB SODIMMs
Maximum
Upgradeable to 16384 MB with optional 8192 MB SODIMMs in slots 1 and 2
Dual-channel
Maximized dual-channel performance requires SODIMMs of the same size and speed in both memory slots.
NOTE:
Due to the non-industry standard nature of some third-party memory modules, we recommend HP branded memory to
ensure compatibility. If you mix memory speeds, the system will perform at the lower memory speed. With Windows Starter 32-
bit operating systems, the amount of usable memory is dependent upon your configuration, so that above 3 GB all memory may
not be available due to system resource requirements.
