Micro ATX B75 board for LGA 1155 CPUs

The MSI B75MA-E31 is a micro ATX motherboard built around the Intel B75 chipset and the LGA 1155 socket. It accepts 3rd generation Intel Core i7, i5, i3, Pentium and Celeron processors. Dual-channel DDR3 memory is supported up to 16 GB across the available slots.

Verify socket, memory and expansion space

Confirm that the processor you intend to use fits the LGA 1155 socket and that your cooler clears the board layout. Check that your DDR3 modules match the supported speeds up to 2400 MHz and that the total capacity does not exceed 16 GB. The board provides one PCIe 3.0 x16 slot, one PCIe 2.0 x1 slot and one legacy PCI slot for add-in cards.

Realtek audio and gigabit LAN stay stable

The onboard Realtek ALC887 codec delivers 8-channel audio compliant with Azalia 1.0. Network connectivity uses a Realtek 8111E controller providing 10/100/1000 Ethernet over a PCI Express link. Four USB 2.0 ports on the rear panel handle peripheral traffic without adding extra controllers that could increase heat under sustained load.
