Your Predator Helios 18 AI supports dual-channel DDR5 memory and can handle up to 192 GB using four SO-DIMM modules, with speeds up to 4400 MT/s. For the best performance, we recommend using memory modules from the same brand and with the same capacities, as mixing different memory modules could lower the memory speed of your computer.
If you want to install DDR5 memory modules in your PH18-73 computer, you need to install them in the right slot. To make sure you install them in the right order, follow the steps below.
