MSI Z270 targeted upgrade

This 4GB DDR4 DIMM is built specifically for the MSI Z270 GAMING PRO CARBON and Z270 GAMING M5 motherboards. It delivers 2133MHz speed with CL15 latency at the standard 1.2V voltage. The single stick adds capacity directly to one of the board's four slots.

Builders filling one slot

The module suits owners of the listed MSI boards who need a straightforward capacity increase without ECC or registered buffering. It is not for systems requiring error correction, registered memory, or speeds beyond the DDR4 2133 specification. Buyers with different motherboards must verify compatibility before purchase.

DDR4 2133 CL15 specification

The decisive figure is the DDR4 2133 (PC4 17000) rating combined with CL15 15-15-15 timing at 1.2V. This exact speed and latency profile must match the memory controller requirements of the target Z270 platform. A module with different timing or voltage will not deliver the guaranteed compatibility.

Questions about this item

Does my MSI Z270 GAMING PRO CARBON motherboard need a specific BIOS version to recognise this 2133MHz DDR4 DIMM?

The module runs at standard DDR4 2133MHz with CL15 timing and 1.2V, which the Z270 platform supports natively; no special BIOS update is required for basic operation.

Can I add this 4GB stick to the three other slots on my Z270 GAMING M5 without exceeding the board limit?

The board accepts up to 64GB across four slots, so a single 4GB module leaves ample room for three more sticks.

How do I confirm the memory is running at the rated 2133MHz CL15 after installation?

Open the BIOS or a system-information utility and verify the memory frequency shows 2133MHz with timings of 15-15-15.
