Compact LGA 1151 platform

This Mini-ITX board pairs the Intel B150 chipset with an LGA 1151 socket for 6th Gen Core i3, i5 and i7 processors plus Pentium and Celeron models. It targets builders who need a small-footprint foundation for a home or office system. The dual-channel memory controller accepts up to 32 GB of DDR4 2133 MHz RAM.

Interface limits in practice

Storage connects through one M.2 interface and four SATA III ports, while expansion relies on a single PCIe 3.0 x16 slot. Networking uses a Realtek RTL8111H Gigabit LAN controller. The rear I/O supplies two USB 3.1 Gen1 ports and four USB 2.0 ports, with two more of each available via onboard headers.

Installation notes

The compact layout keeps the CPU socket clear for most low-profile coolers, though tall memory modules can interfere with larger heatsinks. Front-panel headers sit along the bottom edge and follow the standard pin-out, so miswiring is the most common issue. Audio uses a Realtek ALC887 codec for 7.1 channel output, and a CMOS battery plus one SATA cable are included in the box.

Questions about this item

Should I choose 16 GB or 32 GB of DDR4 for this board?

The board supports dual-channel DDR4 at 2133 MHz up to 32 GB, so 32 GB uses the full capacity while 16 GB leaves room for later upgrades.

What does the 2133 MHz DDR4 rating mean once the board is running?

Memory will operate at 2133 MHz in dual-channel mode; installed modules rated higher will downclock to this speed.

How fast is the M.2 interface on this board in practice?

The single M.2 slot connects through the B150 chipset using SATA bandwidth, limiting drives to SATA III speeds.
