HP EliteDesk DDR4 UDIMM upgrade

This OWC 16GB DDR4 3200MHz CL22 module is a 288-pin non-ECC UDIMM built for HP EliteDesk 800 G6, 800 G8 and 805 G6 desktops. It runs at 1.2V and meets JEDEC PC4-25600 specifications for a warranty-safe memory increase.

Suited for compatible EliteDesk SFF and Tower owners

Buyers needing ECC error correction or registered DIMM pinouts cannot use this unbuffered stick. Systems limited to lower maximum densities or proprietary form factors should look elsewhere.

Deciding spec: 16GB DDR4 3200 CL22 288-pin UDIMM

The single figure that confirms fitment is the 16GB DDR4 3200MHz CL22 288-pin unbuffered DIMM standard. If your EliteDesk model appears in the validated list this module will install and run at the rated speed.

Questions about this item

How do I install the 288-pin DDR4 UDIMM in my HP EliteDesk 800 G6, and what step is often missed?

Power off and unplug the system, open the case, align the notch on the module with the slot key, press firmly until both side clips click shut, then power on and verify 3200 MHz operation in BIOS — the step most often missed is fully seating the module so both clips engage.

What maintenance or replacement will this 16 GB DDR4 module need over its service life?

No scheduled maintenance is required; the module has no heat spreader and runs at 1.2 V, so keep interior dust clear for airflow. Replacement is only needed if a memory test reports errors or you expand capacity beyond the board’s maximum.

What limit appears first when this CL22 3200 MHz memory runs sustained workloads on the EliteDesk 805 G6?

The primary limit is the CAS latency of 22 cycles at 3200 MHz; under continuous load the memory controller will throttle to JEDEC-standard timings before thermal or voltage constraints become a factor.
