Socket and chipset

This motherboard uses the Intel Z170 chipset with an LGA 1151 socket for 6th generation Intel Core i3, i5, i7, Pentium and Celeron processors. It fits a standard ATX case layout. The board provides the platform foundation for a gaming or enthusiast desktop build.

Memory capacity and speed

Four DDR4 slots support up to 64 GB of dual-channel memory at speeds from 2133 MHz to 3600 MHz when overclocked. This maximum capacity decides whether the board suits high-memory workloads or large gaming setups. Populate the slots with matched modules to enable dual-channel operation.

Expansion and connectivity

Two PCIe 3.0 x16 slots, two PCIe 3.0 x1 slots and three PCI slots give room for graphics cards, sound cards and legacy add-in cards. Storage connects through one M.2 interface, two SATA Express interfaces and six SATA III ports. Rear I/O includes two USB 3.1 Gen2 10 Gbps ports, four USB 3.1 Gen1 ports, two USB 2.0 ports and a Killer E2400 Gigabit LAN port. Realtek ALC1150 audio delivers 7.1 channel output with S/PDIF.

Questions about this item

What does the 64GB DDR4 limit mean for a typical build?

The board supports up to 64GB of dual-channel DDR4, so you can install four 16GB modules running at speeds from 2133MHz up to 3600MHz when overclocked.

How fast can the M.2 slot actually run with a SATA drive?

The single M.2 interface is wired for SATA, so any drive installed there is capped at the SATA III 6Gbps throughput.

Will this ATX board fit in a standard mid-tower case?

Yes, the ATX form factor matches the mounting holes and I/O shield cut-out of any regular mid-tower or full-tower chassis.
