Can I upgrade the memory on the Predator G9-591 and G9-571
Predator G9 laptops are upgradable to 64 GB of DDR4 SDRAM. You can install additional memory by removing the access panel on the bottom of the system. The system has two internal memory slots that are not user accessible, and two memory slots on the bottom of the system are accessible via a removable panel. Each memory slot can hold up to 16 GB memory modules.
Note: The user accessible memory slots are independent from the internal slots so installed RAM does not have to match the size of the internal memory when upgrading.
