Compatible 16 GB DDR4 DIMM

This 16 GB DDR4 module runs at 2666 MHz with CL19 timings and 1.20 V operation. It uses a 288-pin unbuffered non-ECC design built with 2Rx8 organisation. The stick is validated for HP EliteDesk Engage Flex Pro and ENVY Desktop 795-0037cb systems.

Verify slot count and maximum capacity

The target platforms provide four DIMM sockets and support up to 64 GB total memory. Confirm how many slots are already populated before ordering. A 64-bit operating system is required to address more than 4 GB of installed RAM.

Steady throughput at rated voltage

Under sustained load the module maintains its 2666 MHz data rate at the standard 1.20 V without a heat spreader. All installed memory will run at the speed of the slowest module or the processor limit, so matching pairs are recommended for consistent bandwidth.

Questions about this item

Does the box contain only the 16GB DDR4 2666 CL19 2Rx8 DIMM stick or are any extra parts included?

The package includes one 288-pin DDR4 2666 CL19 2Rx8 DIMM rated at 1.20V and nothing else; no cables, brackets or tools are supplied.

Should I choose the single 16GB module or look for a matched pair to reach the 64GB maximum across the four slots?

The system supports up to 64GB over four sockets; installing two identical 16GB sticks in matched slots enables dual-channel bandwidth, while a single stick leaves the other channels empty.

Will the 2666MHz CL19 timing run at its rated speed on the EliteDesk Engage Flex Pro and ENVY Desktop 795-0037cb?

The modules are validated for those models and will operate at DDR4-2666 CL19 provided the CPU memory controller supports that frequency; otherwise they down-clock to the highest speed the processor allows.
