Compatible HP ProDesk upgrade

This 8GB DDR4 module is built for HP ProDesk 400 G4 SFF, 400 G4 Tower, 600 G3 SFF and 600 G3 Tower systems. It delivers a straightforward capacity increase for office workstations that need more memory headroom. The unbuffered UDIMM design fits standard desktop DIMM slots without requiring registered memory support. Buyers with other platforms or laptop SODIMM slots cannot use this part.

Thermals and power profile

Operating at 1.2V, the module runs at the standard DDR4 voltage for low power draw and minimal heat output. No heat spreader is fitted, so airflow across the PCB handles cooling in typical chassis layouts. The CL17 latency at 2400MHz keeps timing overhead modest during sustained workloads. Noise is not a factor as the component has no moving parts.

Decisive specification

The 288-pin DDR4 2400 PC4-19200 CL17 1.2V Non-ECC unbuffered 1Rx8 configuration determines fit and function. Systems must accept this exact speed, voltage, pin count and error-correction type. Backward compatibility with 2133MHz buses is supported. If your motherboard requires ECC, registered DIMMs, a different voltage or a different pin layout, this module will not work.

Questions about this item

How do I install this 288-pin DDR4 UDIMM in an HP ProDesk 400 G4 SFF, and what step is often missed?

Power off the PC, unplug it, open the case, align the notch on the module with the slot key, press firmly until both retention clips click shut, then power on and verify 2400 MHz operation in BIOS — the step most people miss is fully seating both clips.

What maintenance or replacement will this 8 GB CL17 module need over its service life?

No scheduled maintenance is required; the module has no heat spreader and no moving parts, so replacement is only necessary if a memory test reports errors or if you later expand beyond the board's maximum capacity.

What limit appears first when this 1.2 V DDR4 2400 memory runs under sustained heavy workloads?

The JEDEC-specified 1.2 V operating voltage and CL17 latency define the thermal and timing envelope; sustained loads stay within that envelope because the module is unbuffered and runs at standard desktop power levels.
