32GB DDR4 SODIMM Kit for HP EliteDesk 800 G4

This 32GB kit contains two 16GB DDR4 SO-DIMM modules built for HP EliteDesk 800 G4 Desktop Mini and EliteOne 800 G4 All-in-One systems. It targets owners of those specific machines who need to reach the platform's maximum supported memory. The modules are unbuffered, non-ECC and run at 1.2V.

2666MHz CL19 capacity and headroom

Each stick delivers 16GB at DDR4 2666 (PC4 21300) with CL19 19-19-19 timing. The pair fills both available sockets to reach the 32GB ceiling for these models. Buyers who want more storage or who use boards requiring ECC or registered memory cannot use this kit.

Two-module pack with lifetime exchange

The box supplies two memory sticks and nothing else. Computer Memory Solutions provides a limited lifetime exchange or repair warranty against manufacturing defects when purchased directly from them. No software, heat spreaders or additional accessories are included.

Questions about this item

Will these 2666MHz DDR4 SODIMMs work alongside any existing DDR4 modules already installed in my EliteDesk 800 G4 Mini?

The kit is validated for the EliteDesk 800 G4 Desktop Mini and EliteOne 800 G4 All-in-One. If the existing modules are also DDR4 SODIMMs, the system will run all sticks at the lowest common speed and timing.

How can I confirm the new 32GB kit is running at 2666MHz with CL19 timings after installation?

Open Task Manager or a tool like CPU-Z; the memory tab should show 32GB total, 2666MHz speed and 19-19-19 CAS latency for each 16GB module.

What exactly ships in the box and is anything else required to complete the upgrade?

The package contains two 16GB DDR4 260-pin SODIMM sticks. No additional parts or tools are needed for the EliteDesk 800 G4 Mini or EliteOne 800 G4 All-in-One.
