32GB DDR5 Kit for MSI X670E Gaming Plus WiFi

This 32GB kit contains two 16GB DDR5 4800 UDIMM modules built for the MSI X670E Gaming Plus WiFi motherboard. The 1Rx8 unbuffered non-ECC design runs at 1.10V with CL40 timing. It targets builders upgrading that specific board with 32GB of system memory.

Installation fits standard DDR5 DIMM slots

The 288-pin modules insert vertically into the four DDR5 slots. Seat each stick until the side clips click. Common issues include mixing this kit with other speeds or capacities, populating the wrong slot pair for dual-channel, or forgetting to enable the XMP or EXPO profile in BIOS for rated 4800 operation.

DDR5 4800 PC5-38400 defines the practical ceiling

The JEDEC DDR5 4800 standard sets the baseline data rate and voltage for this kit. Higher frequencies require motherboard and CPU memory-controller support beyond the base specification. Four-slot population on this platform may force lower speeds or looser timings than the rated CL40 1Rx8 configuration.

Questions about this item

How can I confirm the kit is running at 4800 MT/s and CL40 after installation?

Open Task Manager or CPU-Z and check that the memory speed reads 4800 MT/s with timings showing CL40; the SPD table should also list PC5-38400.

What does the package contain and do I need any extra parts for a desktop build?

The box includes two 16 GB 288-pin UDIMM modules for a total of 32 GB; no additional cables, brackets or cooling are required.

Should I choose the 32 GB 2×16 GB kit or a different capacity for my MSI X670E Gaming Plus WiFi board?

This 32 GB kit (2×16 GB) matches the board’s dual-channel layout and validated speed of 4800 MT/s, making it the correct capacity for that motherboard.
