Capacity and fit

This 16 GB kit delivers two 8 GB DDR4 DIMMs built for the HP EliteDesk 800 G4 Tower, SFF and Workstation Edition. It adds 16 GB of system memory to machines that support up to 64 GB across four slots.

Sustained operation

Unbuffered non‑ECC modules run at 2666 MHz with CL19 timings and 1.20 V, so latency and throughput stay consistent during long workloads. The 2Rx8 rank layout keeps signal integrity stable across all four memory channels.

Platform limits

The EliteDesk 800 G4 platform caps total memory at 64 GB and provides four 288‑pin slots. All installed DIMMs operate at the slowest module speed or the processor’s maximum supported rate.

Questions about this item

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

Each module operates at 1.20 V; total system draw depends on CPU load and the 800 G4 motherboard, not on the memory alone.

What must my EliteDesk 800 G4 already have so these two 288-pin DIMMs will work?

The 800 G4 Tower, SFF or Workstation Edition with four DDR4 slots and a 64-bit operating system.

If I keep the original 8 GB stick in my 800 G4 and add this 2x8 GB kit, what speed will all memory run at?

All modules will run at the slowest installed speed; the kit is rated 2666 MHz CL19, so the system will not exceed that.
