Computer Memory Solutions CM1024642666DIMM 8GB DDR4 2666 CL19 memory upgrade

What this memory is and who it suits

This 8 GB DDR4 module runs at 2666 MHz with CL19 timings and 1.20 V operation. It is built as a 288-pin unbuffered DIMM using a 2Rx8 configuration and carries no ECC or heat spreader. The stick targets owners of HP EliteDesk 800 G4 Tower, SFF or Workstation Edition systems who need a single-slot capacity increase.

Behaviour under sustained load

The module operates at standard JEDEC voltage and timings, so thermal output remains modest during extended workloads. Without a heat spreader, airflow across the PCB handles dissipation in the supported chassis. All installed memory will run at the slowest module speed or the processor’s memory controller limit, whichever is lower.

Checks before ordering

Verify your system has a free 288-pin DDR4 slot and that the platform supports non-ECC unbuffered DIMMs. The EliteDesk 800 G4 family accepts up to 64 GB across four sockets, so confirm the current population leaves room for this stick. A 64-bit operating system is required to address more than 4 GB of total memory.
