OWC 8GB DDR4 for HP 290 and 295

This OWC module adds 8GB of DDR4 memory to HP 290 G1 through G4 and HP 295 G6 desktops. It targets owners of those specific models who need a straightforward capacity increase. Buyers with other platforms or laptops cannot use this UDIMM.

JEDEC compliant 288 pin unbuffered DIMM

The stick follows JEDEC PC4-21300 specifications at 2666MHz CL19 and runs at 1.2V without a heat spreader. Its 288 pin unbuffered non ECC design fits standard desktop slots and will also operate in systems rated for 2133MHz or 2400MHz. Systems requiring ECC or registered memory are not supported.

Lifetime warranty and installation video

OWC backs the module with a limited lifetime warranty and an advanced replacement programme plus free technical support. An online installation video guides first time upgraders through the process. No extra cables, brackets or software licences are included.

Questions about this item

What speed does the PC4-21300 DDR4 2666MHz module actually run at in an HP 290 G3?

It will operate at 2666MHz CL19 at 1.2V; if the platform only supports 2400MHz or 2133MHz the JEDEC SPD automatically down-clocks to the highest speed the board allows.

Will the 288-pin unbuffered UDIMM fit the HP 295 G6 chassis without a heat spreader?

Yes, the bare 288-pin UDIMM is the standard desktop form factor used by the 295 G6; no spreader means it clears even low-profile CPU coolers.

Which slot should I populate first on the HP 290 G4 for a single 8GB stick?

Install the module in the DIMM slot closest to the CPU socket — usually labelled DIMM1 or Channel A Slot 0 — so the memory controller trains at 2666MHz instead of falling back to a lower speed.
