4GB DDR4 DIMM for MSI Z170A boards

This 4GB DDR4-2400 module is built for MSI Z170A Tomahawk and Z170A Gaming Pro motherboards. It targets owners of those boards who want a simple capacity increase without mixing speeds or timings. The single stick leaves three slots free for later expansion.

Straightforward DIMM installation

Align the notch on the 288-pin stick with the slot key, press down until the latches click, and the board will detect it at 2400MHz. The most common issue is leaving a latch unlatched, which causes the system to show less memory than installed. No heat spreader means tall CPU coolers will not interfere.

4GB stick in a 64GB four-slot platform

One module gives 4GB of usable memory, enough for light office work and older games. The platform maximum is 64GB across four sockets, so headroom remains for three more sticks. Buyers who need 16GB or more today should add matching modules rather than rely on this single kit.

Questions about this item

How can I verify the module is running at 2400MHz and CL17 after installation?

Open the BIOS or a tool such as CPU-Z; the memory tab should show DDR4-2400 speed and 17-17-17 timings at 1.2V.

What comes in the box and is anything else required for the MSI Z170A Tomahawk?

The package contains one 4GB 288-pin DIMM stick; no extra cables, brackets or software are needed for the listed motherboards.

Should I choose the 4GB stick or add more to reach the 64GB maximum on four slots?

Each slot accepts one module; four 4GB sticks give 16GB total, so add more 4GB kits if you need capacity toward the 64GB limit.
