Kit contents and target systems

This kit supplies two 16GB DDR4 SO-DIMM modules for a total of 32GB. It is built for the Acer Predator 15 G9-591-74KN and Predator 17 G9-791-735A and G9-791-78CE notebooks. The unbuffered, non-ECC design matches the factory specification for these gaming laptops.

Upgrade path and when it matters

The supported platforms accept up to 64GB across four slots, so this 32GB kit fills half the capacity. The jump is worthwhile when the original 8GB or 16GB configuration limits multitasking, video editing or virtual machines. Buyers who want more storage or who need ECC registered memory for a workstation should look elsewhere.

Installation notes and common issues

Each stick uses the standard 260-pin DDR4 SO-DIMM form factor and runs at 1.2V with CL15 timing. Insert the modules into the empty slots until the side clips click; no tools are required. The most frequent problem is mixing these sticks with slower or mismatched kits, which can force the system to downclock or fail to boot.

Questions about this item

Will the 260-pin DDR4 SODIMM modules fit the four memory slots in my Acer Predator 15 G9-591-74KN?

Yes, each 16GB stick uses the standard 260-pin DDR4 SO-DIMM form factor that matches the four slots in the Predator 15 G9-591-74KN, G9-791-735A and G9-791-78CE notebooks.

What is the correct order for installing the two 16GB sticks into the four slots so the system runs in dual-channel mode?

Populate the two slots belonging to the same memory channel first — usually slots 0 and 2 or 1 and 3 — then add the second pair if you later expand toward the 64GB maximum.

When should I consider replacing these CL15 1.2V modules if I later upgrade to faster DDR4?

Replace them only if you install higher-speed DDR4 SODIMMs that exceed the 2133MHz rating; otherwise the CL15 1.2V kit will continue operating at its rated speed for the life of the notebook.
