MEMORY
Standard
DDR 3L PC3L-12800 (1600 MHz)
Two SODIMM slots supporting dual-channel memory
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.
* Maximum memory capacities assume Windows 64-bit operating systems or Linux. With Windows 32-bit operating systems,
memory above 3 GB may not all be available due to system resource requirements.
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.
