What this module is and who it fits

This 4 GB DDR4 DIMM is built for HP and Compaq Business Desktop 280 G3 Microtower and 280B G2 Small Form Factor systems. It serves owners of those exact models who need a single stick to reach the board’s 32 GB limit across two slots.

The spec that decides compatibility

The stick runs at 2400 MHz with CL17 timings at 1.2 V and uses a 288-pin unbuffered, non-ECC layout. If your desktop requires a different speed, voltage or pin count this module will not work.

Installation notes and common pitfalls

Installation is a standard DIMM insertion into an empty slot; no heat spreader means low-profile coolers clear it easily. The main issue is mixing speeds or capacities — the board will down-clock to the slowest stick, so confirm the existing module matches 2400 MHz CL17 before adding this one.

Questions about this item

How does the 2400 MT/s speed translate to real-world bandwidth in this HP desktop?

The DDR4-2400 rating gives a peak transfer rate of PC4-19200, and the CL17 timing keeps latency low for everyday office workloads.

What does the 288-pin DDR4 interface mean for compatibility with the 280 G3 Microtower?

The 288-pin DIMM fits the desktop's standard DDR4 slots and runs at 1.2 V without requiring ECC or registered memory support.

Will the 4 GB stick physically fit inside the 280B G2 Small Form Factor chassis?

Yes, the unbuffered 288-pin DIMM uses the standard height and keying for both the Microtower and Small Form Factor models listed.
