HP 280 & 285 desktop upgrade

This 16GB DDR4 2666MHz CL19 module is built for HP 280 G3 through G6 and 285 G3 systems. It delivers a warranty-safe memory increase for office desktops and workstations that use 288-pin unbuffered DIMMs. The 1.2V JEDEC-standard part installs without BIOS changes.

Fits single-slot UDIMM layouts

The stick uses a standard 288-pin unbuffered form factor with 2Rx8 organisation and no heat spreader. It slots directly into the motherboard memory sockets of the compatible HP models. Backward compatibility with 2133MHz and 2400MHz buses lets it run in older configurations without manual tuning.

Tested module with lifetime cover

Every unit is validated in OWC's lab to meet or exceed the OEM specifications for the listed HP desktops. The package includes only the memory module itself; no extra cables, brackets or software discs are supplied. Free technical support is available from the manufacturer for the life of the product.

Questions sur cet article

Will the CL19 latency limit throughput during sustained workloads?

CL19 is the rated CAS latency for DDR4 2666 operation; sustained throughput follows JEDEC timings at this speed.

How much heat or extra power does the module add when running all day?

It runs at the standard 1.2 V DDR4 voltage with no heat spreader, so thermal and power impact matches baseline JEDEC unbuffered DIMMs.

Which HP desktops must I already own for this 288-pin UDIMM to work?

Qualified systems are HP 280 G3, G4, G5, G6 and 285 G3; the module also down-clocks to 2133 MHz or 2400 MHz if the platform requires it.
