Targeted DDR4 Upgrade for HP ProDesk 400 G3

This 4 GB DDR4-2133 module is built for the HP ProDesk 400 G3 Microtower. It runs at 1.2 V with CL15 timings and uses a standard 288-pin DIMM form factor. The stick is unbuffered, non-ECC and organised as 2Rx8. It suits office PCs that need a simple capacity boost.

Verify Slot Count and Maximum Capacity

The ProDesk 400 G3 Microtower accepts either two or four DIMM slots with a 32 GB ceiling. Count the free slots on your board before ordering. Ensure the system BIOS is current so the new module is recognised at its rated 2133 MHz speed.

Fits Microtower Chassis, Leaves Room for Expansion

The low-profile DIMM clears standard CPU coolers inside the Microtower case. Adding a single 4 GB stick keeps remaining slots open for future upgrades up to the 32 GB limit. No heat spreader means it sits flush in tight layouts without blocking adjacent components.

Questions about this item

Does the CM512642133DIMM box contain only the 288‑pin DDR4 module or are cables or tools included?

The package contains one 4GB DDR4 2133MHz CL15 288‑pin DIMM stick; no cables, brackets or tools are supplied.

Should I choose the single 4GB stick or add a second one for the ProDesk 400 G3 Microtower?

The board accepts up to 32GB across four slots, so one 4GB module works alone and a second can be added later for dual‑channel performance.

Will the CL15 2133MHz rating deliver the advertised speed once installed in the HP ProDesk 400 G3?

The module runs at DDR4‑2133 (PC4‑17000) with 15‑15‑15 timings at 1.2V, matching the system’s supported memory specification.
