Memory upgrades matched to your MSI desktop motherboard. Each listing covers one MSI board, using the memory generation, speed and module size that board supports, in single modules and matched kits. To find yours, type the MSI model name into the search bar at the top of the page, for example MAG B850 TOMAHAWK MAX WIFI, PRO Z790-A WIFI, MPG X870E CARBON WIFI or B550 GAMING GEN3. The model name is printed on the board between the slots, on the box, and in the BIOS main screen.

Which memory does my MSI motherboard use?

DDR5 UDIMM: all AM5 and LGA1851 boards, and most LGA1700 boards. Listed as DDR5-5600 in 16GB, 32GB and 48GB modules, sized to each board's maximum capacity. See DDR5 UDIMM.
DDR4 UDIMM: AM4, LGA1200 and LGA1151 boards, DDR4 versions of LGA1700 boards, and TRX40 / X299. Listed as DDR4-3200 in 8GB, 16GB and 32GB modules. See DDR4 UDIMM.
DDR4 RDIMM / LRDIMM: WS WRX80 for AMD Threadripper PRO. See DDR4 RDIMM.

DDR5 and DDR4 modules are keyed differently and are not interchangeable. The high memory speeds on MSI's box are overclocking (XMP / EXPO) figures. NEMIX modules run at their standard JEDEC speed, or at the lower speed the processor supports, and each listing states the speed on that board.

How to choose MSI motherboard memory

Match the generation (DDR5 or DDR4) to your board and stay within its maximum capacity. For dual-channel performance, install identical modules in matched pairs in the slots MSI recommends (usually A2 and B2 on four-slot boards). On eight-slot TRX40 and X299 boards, install modules in sets of four for quad-channel operation. 48GB DDR5 modules need a current BIOS; update the BIOS before installing them. Not sure which module fits? Send us your MSI model name and we will confirm the right module before you order.
