LGA 1151 (300 Series) micro-ATX board for 8th

This micro-ATX motherboard uses the Intel B360 chipset and the LGA 1151 (300 Series) socket. It accepts 8th Generation Intel Core processors and is not backward compatible with older LGA 1151 CPUs. The board provides four DDR4 memory slots with dual-channel support up to 64 GB total capacity. Two M.2 slots and four SATA 6Gb/s ports handle storage, while a Realtek ALC892 codec delivers eight-channel audio.

Sustained load on the extended PWM heatsink

The extended PWM heatsink and enhanced circuit design keep temperatures lower when a high-core-count processor runs continuously at full speed. Multiple fan headers with full PWM control let the builder match airflow to the thermal load. An Intel I219-V Gigabit LAN controller maintains a steady 1 Gbps network link during long transfers. Onboard video outputs — HDMI, DisplayPort and DVI — remain active only when the installed CPU includes integrated graphics.

64 GB DDR4 dual-channel memory ceiling

Four 288-pin DDR4 slots operate in dual-channel mode and top out at 64 GB of system memory. This limit defines the maximum RAM the platform can address and therefore decides whether the board suits a given workload. Exceeding this capacity is not possible on the B360 chipset, so buyers with larger memory requirements must choose a different chipset.

Questions about this item

How loud does the board get when an 8-core i7 runs full speed all day?

The extended PWM heatsink and enhanced circuit design keep an 8-core i7 at full speed without extra noise, so fan headers stay at low RPM under sustained load.

Which memory kits must I already own for the four 288-pin slots?

Four DDR4 modules up to 64 GB total in dual-channel mode; the board does not accept older DDR generations.

Will my older LGA 1151 processor work in the 300-series socket?

The 300-series socket only supports 8th Generation Intel Core processors; earlier LGA 1151 CPUs are not compatible.
