OWC 16GB DDR4 2400MHz desktop memory

This 16GB DDR4 UDIMM runs at 2400MHz with CL17 latency at 1.2V. It is a non-ECC, unbuffered module built to JEDEC specifications for HP ProDesk 400 G4 and 600 G3 small form factor and tower systems. The 288-pin DIMM installs easily as a warranty-safe upgrade.

Suits owners of the listed HP ProDesk models

Buyers needing ECC error correction, registered modules, or laptop SO-DIMM form factors cannot use this memory. Systems requiring speeds above 2400MHz or different pin counts should look elsewhere. The module is backward compatible with 2133MHz operation.

16GB capacity determines the upgrade scale

The single 16GB stick doubles typical 8GB configurations or fills a vacant slot in the compatible HP desktops. Rank is 2Rx8. No heat spreader is fitted. Verify the exact model number before purchase.

Questions about this item

How much heat does the 1.2V DDR4 module add during all-day use?

The module runs at the standard JEDEC 1.2 V, so it draws minimal power and generates very little extra heat inside a ProDesk 400 G4 or 600 G3 chassis.

What motherboard slot must my HP ProDesk already have for this 288-pin UDIMM to work?

Your ProDesk 400 G4 SFF, 400 G4 Tower, 600 G3 SFF or 600 G3 Tower needs a free DDR4 288-pin UDIMM slot; the module is unbuffered, non-ECC and 2Rx8.

Will the 2400MHz CL17 stick run stably alongside existing 2133MHz memory in a ProDesk 600 G3?

Yes — the module is backward compatible with 2133 MHz, so it will down-clock and run at the slower speed when mixed with older DDR4 DIMMs.
