Memory compatibility and supported speeds vary according to the installed processor, memory modules and DIMM configuration. The primary PCIe slot operates at PCIe 5.0 x16 with Ryzen 9000 and 7000 Series processors, PCIe 4.0 x8 with Ryzen 8700, 8600 and 8400 Series processors, and PCIe 4.0 x4 with Ryzen 8500 and 8300 Series processors. M.2_1 supports up to PCIe 5.0 x4 with Ryzen 9000 and 7000 Series processors and up to PCIe 4.0 x4 with Ryzen 8000 Series processors. M.2_2 is unavailable with Ryzen 8500 and 8300 Series processors. The rear USB 40Gbps Type-C ports and M.2_2 share bandwidth. With an M.2_2 device installed, both operate at PCIe 5.0 x2; configuring M.2_2 for PCIe 5.0 x4 in BIOS disables the USB 40Gbps Type-C ports. HDMI and USB-C DisplayPort video outputs require a processor featuring integrated graphics. RAID 5 for M.2 NVMe is supported only with Ryzen 9000 Series processors, while M.2 NVMe RAID 10 is supported only with Ryzen 9000 and 7000 Series processors.
