4GB DDR3 module for HP 280 G1

This 4GB DDR3 DIMM is built for the HP 280 G1 Microtower. It uses a 240-pin unbuffered design and runs at 1600 MHz with CL11 timing. The stick adds memory capacity to compatible desktops without requiring ECC or registered support.

PC3-12800 speed rating

The module operates at the PC3-12800 standard, delivering a 1600 MHz data rate at 1.5 V. This exact speed rating is the deciding factor for correct operation in the specified HP systems. Installing a different DDR3 speed grade will prevent the memory from functioning as intended.

Standard voltage and no heat spreader

At 1.5 V the module draws the usual power for DDR3 and runs without a heat spreader. In normal desktop use it produces minimal heat and no audible noise, relying on case airflow for passive cooling. Power draw stays within the standard limits for unbuffered DDR3 DIMMs.

Questions about this item

What does the 1600 MHz speed mean when the module is installed in an HP 280 G1 Microtower?

The module runs at DDR3-1600, also labelled PC3-12800, delivering a peak transfer rate of 12 800 MB/s on the platform's memory controller.

How does the 240-pin DDR3 interface limit the upgrade?

The 240-pin DIMM fits only DDR3 slots; the HP 280 G1 Microtower has two such sockets and a 16 GB maximum, so this 4 GB stick leaves one slot open for another DDR3 module.

What physical space and power does the stick need inside the chassis?

It is a standard-height unbuffered 240-pin DIMM drawing 1.5 V with no heat spreader, so it fits the Microtower's DIMM slots without clearance issues.
