Socket 1151 (300 Series) Micro ATX board

This ASRock B365M Pro4 uses the Intel B365 chipset on a Micro ATX form factor. It accepts 8th and 9th Gen Intel Core processors in an LGA 1151 (300 Series) socket. The board is not backward compatible with older LGA 1151 CPUs. Four 288pin DDR4 slots support up to 64GB in dual channel mode at 2666, 2400 or 2133 speeds.

Two PCIe 3.0 x16 slots and dual M.2 sockets

Two full length PCI Express 3.0 x16 slots provide expansion for graphics or other add in cards and both support NVMe SSD as boot disks. One Ultra M.2 socket (M2_1) takes M Key PCIe modules up to Gen3 x4 (32Gb/s) in 2242, 2260 or 2280 sizes. A second Ultra M.2 socket (M2_2) adds support for 22110 length drives and also accepts M.2 SATA3 6.0Gb/s modules. A third M.2 Socket (Key E) is reserved for a 2230 Wi Fi/BT module.

Six SATA 6Gb/s ports with RAID and 7.1 audio

Six SATA 6Gb/s connectors handle traditional SSDs and hard drives and support RAID 0, 1, 5 and 10 arrays. Realtek ALC892 codec delivers 7.1 channel high definition audio when paired with an HD front panel audio module and the appropriate driver. Intel Optane Ready certification allows compatible Optane memory modules to accelerate mechanical storage. Onboard video output functions only with a CPU that includes integrated graphics.
