32GB DDR4 Kit for HP Prodesk 400 G3/G4

This 32GB kit contains two 16GB DDR4 2400MHz modules built for HP Prodesk 400 G3 Microtower, G3 Small Form Factor and G4 SFF/MT systems. It uses non-ECC unbuffered DIMMs with CL17 timings at 1.2V. The kit targets owners of these specific HP desktops who need to reach the platform’s 32GB maximum across two sockets.

Steady throughput at DDR4 2400 speeds

Running at PC4 19200 with 17-17-17 latency, the modules deliver consistent bandwidth during extended workloads rather than brief bursts. The 2Rx8 organisation and major-brand chipset maintain stable signalling across both sticks. Builders who need error correction or registered memory cannot use this kit.

Low-voltage operation without a heat spreader

The 1.2V rating keeps power draw modest inside the compact Prodesk chassis. No heat spreader is fitted, so airflow from the system fan passes directly over the chips. Buyers who want RGB lighting or tall heat sinks for overclocking headroom should look elsewhere.

Questions about this item

Does the 1.2 V DDR4 kit run cool enough for all-day operation inside a compact ProDesk 400 G3 SFF?

The modules operate at the standard 1.2 V DDR4 voltage and have no heat spreader, so they rely on the chassis airflow; the ProDesk 400 G3 SFF and MT designs are built to cool memory at this voltage during continuous use.

My ProDesk 400 G3 has two DIMM slots — will this 2 x 16 GB kit fill them completely?

Yes, the ProDesk 400 G3 and 400 G4 SFF/MT platforms each provide two 288-pin DDR4 slots, and this kit supplies two 16 GB sticks for a total of 32 GB, matching the documented maximum.

Can I keep one existing 16 GB stick and add a single module from this kit?

The kit is sold as a matched pair of 16 GB modules; using only one stick would leave the second slot empty and would not take advantage of the dual-channel design validated for these ProDesk models.
