16GB DDR4 3200 UDIMM for HP ProDesk

This 16GB DDR4 3200MHz CL22 module is built for HP ProDesk 400 G7 SFF, 400 G7 Tower, 400 G9 SFF, 405 G6 SFF and 405 G8 SFF systems. It runs at 1.2V on a standard 288-pin unbuffered non-ECC layout. JEDEC compliance makes it a warranty-safe upgrade for those desktops.

Suits owners of the listed ProDesk models.

Buyers who need ECC error correction or registered buffering should look elsewhere. Systems that require a different pin count, voltage or form factor cannot use this module. The part is validated only for the five HP ProDesk families named in the specifications.

Speed and latency decide fit

The module operates at DDR4 3200 (PC4-25600) with CL22 timing and 2Rx8 organisation. It will down-clock to 2133, 2400, 2666 or 2933MHz if the platform demands it. Confirm that your ProDesk accepts 3200MHz CL22 before purchase.

Questions about this item

Will the 288-pin UDIMM fit the HP ProDesk 400 G7 SFF memory slots?

Yes, the 288-pin DDR4 UDIMM is the correct form factor for the HP ProDesk 400 G7 SFF and the other listed models.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, press down firmly until both side clips click shut; the step often missed is verifying both clips have fully locked.

When will this 16GB DDR4 3200 CL22 module need replacement?

DDR4 memory has no moving parts and typically lasts the life of the system; replace only if a fault appears or capacity needs increase.
