Socket and Chipset

This is an Intel B150 motherboard with an LGA 1151 socket built on a Micro ATX form factor. It supports DDR4 memory up to 64GB and provides a single PCI Express 3.0 x16 slot plus one legacy PCI slot. The rear panel includes one USB 3.1 Gen 2 Type-A port, one USB 3.1 port and one RJ45 network jack.

Who it suits and who it does not

Builders assembling a compact system around a 6th or 7th generation Intel Core processor will find the board fits small chassis and covers essential connectivity. It is not for users who need multiple graphics cards, M.2 storage or more than four memory slots. Buyers expecting a full accessory kit should look elsewhere as only the I/O shield is included.

Deciding specification

The LGA 1151 socket paired with the B150 chipset defines which processors and memory generation this board accepts. Matching that socket and chipset to the intended CPU is the single check that confirms compatibility.

Questions about this item

What does the 64 GB DDR4 limit mean when I populate the four slots?

The board accepts up to 64 GB of DDR4 across its four DIMM slots, so a full kit of four 16 GB modules reaches the maximum capacity.

How fast is the single USB 3.1 Gen 2 Type-A port on the rear I/O?

The rear USB 3.1 Gen 2 Type-A port runs at the USB 3.1 Gen 2 signalling rate for compatible devices.

Will this MicroATX board fit in a standard MicroATX or larger case?

The MicroATX form factor matches standard MicroATX standoff patterns and fits any case that supports MicroATX or ATX motherboards.
