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.

Perguntas sobre este artigo

How much power does the 1.20V DDR4 2666 module draw when the EliteDesk 800 G4 runs all day?

The stick is rated at 1.20V and unbuffered, so it adds only a few watts to the system power budget during continuous operation.

What must the HP EliteDesk 800 G4 Tower or SFF already have for this 288-pin DIMM to work?

The workstation needs a free DDR4 DIMM slot — up to four sockets are available — and a 64-bit operating system to address the full 8 GB.

If I keep the original memory in my EliteDesk 800 G4 alongside this CL19 2666 MHz stick, what happens?

All installed modules will run at the speed of the slowest module or the CPU limit, so mixing can lower overall memory performance.
