16GB DDR4 2666MHz UDIMM for HP 290 and 295

This OWC module adds 16GB of DDR4 2666MHz memory to compatible HP desktops. It uses a standard 288-pin unbuffered non-ECC design with CL19 latency and 1.2V operation. The kit targets owners of HP 290 G1 through G4 and 295 G6 systems seeking a straightforward capacity increase.

Check your HP model and current memory configuration

Verify that your desktop is an HP 290 G1, G2, G3, G4 or 295 G6 before ordering. Confirm the motherboard has a free 288-pin DDR4 UDIMM slot and that the existing memory runs at 1.2V. The module is backward compatible with 2133MHz and 2400MHz speeds, so mixed-speed installations will downclock to the slowest module.

JEDEC compliance and lifetime warranty support

The memory meets JEDEC standard specifications and is RoHS compliant, ensuring a warranty-safe upgrade for the host system. OWC includes a limited lifetime warranty with free technical support and an advanced replacement programme. No heat spreader is fitted, keeping the module low-profile for tight chassis clearances.
