System-specific DDR4 upgrade kit

This 32 GB kit contains two 16 GB DDR4 SO-DIMM modules rated at 2666 MHz with CL19 timings and 1.2 V operation. It targets owners of HP ProDesk 400 G5 Desktop Mini, 600 G5 Desktop Mini and ProOne 400 G5 All-in-One systems who need the maximum 64 GB capacity across the two available slots.

Sustained-load behaviour

Unbuffered non-ECC DDR4 running at 2666 MHz maintains its rated speed as long as the platform memory controller allows. All installed modules operate at the slowest module or processor limit, so mixing faster sticks provides no benefit. The 2Rx8 organisation and major-brand chipset deliver stable throughput for typical desktop workloads.

Installation notes

The 260-pin SO-DIMM form factor fits the mini-desktop and all-in-one slots without a heat spreader. Buyers who want ECC memory for Xeon processors cannot use this kit, and systems limited to a single slot cannot reach the 32 GB per module density. A 64-bit operating system is required to address the full capacity.

Questions about this item

Does the 1.2 V DDR4 2666 kit run hot or loud when the ProDesk 400 G5 Mini stays on all day?

The modules operate at 1.2 V with no heat spreader, so they add minimal heat and produce no noise inside the compact chassis.

What must the ProDesk 400 G5 Mini already have for this 32 GB kit to work?

The system needs two free 260-pin SODIMM slots and a 64-bit operating system to address the full 32 GB capacity.

Will the CL19 2666 MHz sticks slow down if I keep the original slower modules in the ProOne 400 G5 All-in-One?

All installed memory runs at the speed of the slowest module, so mixing with slower sticks will reduce the kit to that lower rate.
