Manufacturer specification · Supported capacity, module population and profile speeds depend on the exact CPU, installed BIOS and validated memory kit. Profile support does not guarantee an overclock.
The overclocked speed is MSI's 1DPC 1R maximum with Ryzen 9000; MSI lists 1DPC 2R, 2DPC 1R and 2DPC 2R up to 6400+ MT/s. JEDEC speeds are 4800–5600 MT/s. CUDIMMs run in clock-driver bypass mode only. · Manufacturer specification · Manufacturer capacity ceiling for this exact board, not included memory or a performance measurement. CPU, BIOS, DIMM population and the validated-module list determine support. DDR5 slots require DDR5 modules; DDR4 and DDR5 are not interchangeable. CUDIMM support is bypass mode only; compatibility depends on CPU and BIOS, and some combinations may not boot. Check the exact memory support list.
Plan the complete platform. Check the exact CPU-support list, required BIOS and memory validation before buying. PCIe generations and lane allocations can change with the processor. A socket match or slot count is not a guarantee that every component works together at its highest advertised setting.
