Kit composition and target system

This 16GB kit contains two 8GB DDR4 modules built for the HP ProDesk 400 G3 Microtower. The 288-pin DIMMs run at 2133MHz with CL15 timings and 1.2V operation. Non-ECC unbuffered design matches the desktop platform requirements. Buyers needing ECC error correction or registered modules for server boards cannot use this kit.

Sustained-load behaviour

The modules maintain their rated 2133MHz speed and 15-15-15 timings during extended workloads without throttling. Dual-rank 2Rx8 organisation supports full throughput across both sticks. Total capacity of 16GB fits within the system maximum of 32GB across four slots. Users requiring more than 32GB total memory must choose a different platform.

Thermals and power

Bare modules without heat spreaders rely on case airflow for cooling in the microtower chassis. The 1.2V DDR4 standard keeps power draw low during typical office tasks. Silent operation with no moving parts suits noise-sensitive environments. The kit draws only the voltage specified by the JEDEC DDR4 standard.

Questions about this item

How much power do the 1.2V DDR4 modules draw when the ProDesk 400 G3 runs all day?

Each stick operates at 1.2V, the standard DDR4 voltage, so total draw stays low even under continuous load.

Does the HP ProDesk 400 G3 Microtower need a specific BIOS version or four open slots for this 2x8GB kit to work?

The kit is validated for the ProDesk 400 G3 Microtower which has four DIMM sockets and supports up to 32GB total.

Can I keep the factory 2.5-inch drive installed while adding this 288-pin DDR4 memory?

Yes, the memory slots are separate from the 2.5-inch drive bay, so the existing drive remains unaffected.
