16 GB DDR4 2666 Kit for HP Workstations

This 16 GB kit contains two 8 GB DDR4 2666 modules designed for HP EliteDesk 705 G5 SFF, 800 G5 Tower and SFF, and Workstation Z4 G4 (Core X) systems. Unbuffered, non-ECC DIMMs install directly into the 288-pin slots without additional configuration. The kit suits offices and professionals who need a straightforward capacity increase for these specific platforms.

Capacity and Headroom for DDR4 2666 Systems

Each module provides 8 GB at CL19 19-19-19 timing and 1.20 V, giving 16 GB total across the pair. The supported platforms offer four sockets and a maximum of 128 GB, so this kit occupies half the slots and leaves room for further expansion. Performance scales with the slowest installed module or CPU capability, so matching pairs are recommended for best results.

DDR4 2666 Interface Limits

The DDR4 2666 (PC4 21300) interface caps transfer rates at the rated speed, and all modules in the system will run at the lowest common frequency. A 64-bit operating system is required to address more than 4 GB of memory. Builders needing ECC, registered buffering, higher frequencies, or capacities beyond 128 GB must choose a different memory type.

商品問答

Will the 2666 MHz DDR4 modules run at full speed alongside slower DDR4 sticks already in my EliteDesk 800 G5?

All memory in the system will run at the speed of the slowest installed module or the CPU capability, so mixing with slower DDR4 will downclock these 2666 MHz sticks.

How can I verify the kit is recognised at 2666 MHz with CL19 timings after installation?

Check the BIOS memory information or a tool such as CPU-Z; it should report 2666 MHz, CL19-19-19 timing and 1.20 V for each 8 GB module.

Does the package include only the two 8 GB DIMMs or are any brackets or cables supplied?

The package contains two 288-pin DDR4 DIMM modules; no brackets, cables or additional accessories are included.
