Socket 1151 (300 Series) mini-ITX motherboard

The ASRock H310CM-ITX/ac fits Intel 8th and 9th generation Core processors in the LGA 1151 socket. It uses the Intel H310 chipset on a compact mini-ITX form factor. The board targets small-form-factor builds that need integrated graphics output and wireless connectivity.

H310 chipset limits and DDR4 memory

The H310 chipset provides a single PCI Express 3.0 x16 slot and four SATA3 6.0Gb/s ports. One M.2 socket supports SATA or PCIe Gen2 x4 storage up to 20Gb/s. Two DDR4 slots run at 2666, 2400 or 2133 MT/s in dual-channel mode for a maximum of 32GB.

Realtek ALC887 audio with Intel I219-V LAN

Onboard 7.1-channel audio uses the Realtek ALC887 codec and requires an HD front-panel module for full multichannel output. Wired networking is handled by an Intel I219-V controller at 1Gbps. A bundled Intel 802.11ac module in a vertical M.2 Key E slot adds dual-band Wi-Fi up to 433 Mbps.
