Compact LGA 1151 board for 8th

The ASRock B365M-ITX/ac is a Mini-ITX motherboard built around the Intel B365 chipset and the LGA 1151 socket (300 Series). It accepts 8th and 9th Generation Intel Core processors and is not backward compatible with earlier LGA 1151 CPUs. The board targets small-form-factor builds that need a full feature set in a reduced footprint.

DDR4 2666 dual-channel memory and PCIe 3.0 x16 slot

Two 288-pin DDR4 slots support memory speeds of 2666, 2400 and 2133 in dual-channel mode. A single PCI Express 3.0 x16 slot handles discrete graphics or other expansion cards. The M.2 socket accepts M Key modules up to 22110 length and operates at PCIe Gen3 x4 (32Gb/s) or SATA 6.0Gb/s, with Intel Optane Ready support.

Integrated Wi-Fi 802.11 ac, Intel LAN and 7.1 audio

A vertical M.2 Key E socket carries the bundled Wi-Fi 802.11 ac module, with antennas on the rear I/O. Wired networking uses an Intel I219-V controller rated for 1Gbps. Audio is driven by a Realtek ALC887 codec delivering 7.1 channels when paired with an HD front-panel module. Four SATA3 6.0Gb/s ports support RAID 0, 1, 5 and 10.

Questions about this item

Should I choose DDR4 2666, 2400 or 2133 modules for this board?

All three speeds are supported; 2666 MHz gives the highest stock bandwidth, while 2400 and 2133 will run at their rated speeds without manual tuning.

What does the PCIe 3.0 x16 slot deliver for a graphics card in a Mini-ITX build?

The single slot runs at full x16 electrical width, so a discrete GPU gets the full 32 Gb/s bandwidth the chipset provides.

How fast is the Ultra M.2 socket for an NVMe drive?

The M.2 socket connects through PCIe 3.0 x4, capping sequential throughput at 32 Gb/s for compatible NVMe SSDs.
