HP 280 desktop upgrade

This 8 GB DDR4 module is built for HP Business Desktop 280 G3 SFF and the G4 and G5 Microtower models. It delivers 2666 MHz speed with CL19 timing at 1.2 V. The single DIMM adds capacity without requiring a matched pair.

Single stick simplicity

The kit contains one 288-pin unbuffered non-ECC DIMM using 2Rx8 organisation. No heat spreader is fitted, keeping the profile low for small-form-factor chassis. Installation is a direct swap in the supported HP systems.

Two-slot 32 GB ceiling

The compatible platforms provide two memory sockets and a maximum of 32 GB total. This 8 GB stick leaves room for one more module to reach the limit. Builders needing more than 32 GB must choose a different platform.

商品問答

Will the CL19 timing need adjustment after prolonged use?

The module runs at CL19 19-19-19 timing at 1.20 V and does not require timing changes during its service life.

What limit appears first when the 2Rx8 rank runs at 2666 MHz continuously?

The memory controller caps total capacity at 32 GB across the two sockets, so that ceiling is reached before any thermal throttle on this unbuffered DIMM.

How much heat does the 1.20 V stick produce inside an HP 280 chassis all day?

At 1.20 V without a heat spreader, the DIMM stays within standard DDR4 thermal limits during sustained operation in the 280 G3 SFF, G4 or G5 microtower.
