System-Specific DDR4 Kit

This 64GB kit delivers four 16GB DDR4 DIMMs rated at 2666MHz with CL19 timing and 1.20V operation. The unbuffered, non-ECC modules use a 2Rx8 configuration on 288-pin connectors and are validated for specific Acer desktops.

Acer Desktop Upgraders

Owners of Acer Nitro 50-600-xxx, Predator Orion 5000 or Predator Orion 9000 systems can install this kit to reach the platform's 64GB maximum across four slots. Builders using other motherboards, servers requiring ECC or registered memory, or anyone needing lower-voltage or higher-frequency modules should look elsewhere.

Matched Quad-Kit Convenience

The four sticks are sold as a matched set so they can be installed in pairs to support dual-channel operation without mixing different production batches. No heat spreaders, software utilities or additional accessories are included in the package.

Questions about this item

Will the 288-pin DDR4 DIMMs fit the four memory slots on my Acer Predator Orion 5000 Gaming?

Yes, the kit is validated for the Predator Orion 5000 Gaming and uses standard 288-pin DDR4 DIMMs that match the board's four slots.

Can I keep my existing DDR4 2666 CL19 sticks and add this 4×16 GB kit without stability issues?

All modules will run at the slowest installed speed; mixing matched pairs is recommended but the system will default to the lowest common timing.

How do I verify the system sees the full 64 GB after installing the four 16 GB modules?

Boot into a 64-bit OS and check Task Manager or BIOS; both should report 64 GB total capacity across the four slots.
