LGA 1151 ATX motherboard for 6th-gen Intel Core

The MSI B150 GAMING M3 is an ATX board built on the Intel B150 chipset. It accepts LGA 1151 processors including 6th-generation Core i3, i5 and i7 as well as Pentium and Celeron CPUs. Dual-channel DDR4 memory runs at 2133 MHz up to a total of 64 GB.

Gamers and builders needing legacy expansion.

The board suits users who want a B150 platform with seven PCI slots for add-in cards and six SATA III ports for storage arrays. The Killer E2400 Gigabit LAN and Realtek ALC1150 audio appeal to gaming-focused builds. Builders targeting 7th-generation or later Intel processors must choose a different chipset.

B150 chipset limits CPU support to 6th-generation

The Intel B150 chipset defines the compatible processor lineup, restricting upgrades to 6th-generation Core and related LGA 1151 CPUs. This single specification determines whether the board fits an existing system or a planned upgrade path.

Questions about this item

What size ATX case and standoff layout does the MSI B150 GAMING M3 need?

The board follows the standard ATX form factor, so it fits any ATX case with the correct nine-hole standoff pattern and I/O cut-out.

How is the Killer E2400 LAN driver installed after Windows loads?

Run the MSI driver disc or download the latest package, install the Killer Network Manager first, then reboot before connecting the Ethernet cable.

When should the onboard CMOS battery be replaced?

Replace the supplied battery when the system loses time or BIOS settings after being unplugged, typically after several years of use.
