Micro-ATX board for 6th- and 7th-gen Intel CPUs

The ASUS ROG STRIX B250G GAMING uses the Intel B250 chipset and an LGA 1151 socket to support Core i7, i5, i3, Pentium and Celeron processors. It is not compatible with 8th generation Intel CPUs. The Micro-ATX form factor suits compact gaming builds.

Suits compact gaming builds.

Builders who want a small chassis with dual M.2 slots, USB 3.1 and 8-channel SupremeFX audio will fit this board. Anyone planning an 8th generation or later Intel processor must choose a different platform because the socket and chipset do not support those CPUs.

64 GB DDR4 ceiling with dual-channel headroom

Four 288-pin slots accept DDR4 2400 and 2133 modules up to 64 GB total. 7th generation processors reach 2400 MHz; 6th generation processors top out at 2133 MHz. One M.2 slot handles 2242, 2260, 2280 and 22110 lengths over PCIe 3.0 x4 or SATA, while a second slot covers 2242, 2260 and 2280 devices. Six SATA 6 Gb/s ports add further storage room.

Questions about this item

Which processor socket must the CPU I already own fit to work with this motherboard?

The board uses an LGA 1151 socket, so the installed processor must be an LGA 1151 Core i7, i5, i3, Pentium or Celeron.

If I keep my existing DDR4 2400 memory modules, will they run at their rated speed on a 6th Gen Intel processor?

On a 6th Gen Intel processor the memory controller is limited to DDR4 2133, so DDR4 2400 modules will operate at 2133 MHz.

How can I confirm the single PCI Express 3.0 x16 slot is running at full bandwidth after I install a graphics card?

Check the slot configuration in the BIOS or use a system-information utility to verify the link reports PCIe 3.0 x16.
