Socket & generation

The MSI B560M BOMBER uses the LGA 1200 socket and accepts 10th and 11th generation Intel Core, Pentium and Celeron processors. It is built on the Intel B560 chipset and provides a micro-ATX form factor for compact builds. The board delivers a digital power design intended to support multi-core operation.

Memory & PCIe limits

Dual-channel DDR4 memory runs up to 5200 MHz when overclocked, with a maximum capacity of 64 GB. The primary PCIe x16 slot operates at 4.0 with an 11th generation CPU and falls back to 3.0 with a 10th generation CPU. Two additional PCIe 3.0 x1 slots are wired from the chipset.

Storage, LAN & USB checklist

One M.2 slot and six SATA III ports handle storage, while a Realtek 8125B controller provides 2.5 Gbps Ethernet. Rear I/O includes two USB 2.0 Type-A ports and four USB 3.2 Gen 1 5 Gbps Type-A ports; internal headers add four USB 2.0 and two USB 3.2 Gen 1 connections. Audio uses the Realtek ALC897 codec for 7.1-channel output. The package supplies the motherboard, one SATA cable and an I/O shield only.

Questions about this item

Should I pick the 10th or 11th Gen Intel Core for this LGA 1200 board?

Both generations fit the socket. An 11th Gen CPU enables PCIe 4.0 on the x16 slot and the M.2, while a 10th Gen CPU limits those to PCIe 3.0.

What does DDR4 5200 (OC) MHz mean once the board is built?

It is the maximum overclocked memory speed the board can reach with compatible DDR4 modules; default speeds will be lower unless you enable the XMP profile in BIOS.

How fast is the Lightning Gen4 x4 M.2 interface in practice?

With an 11th Gen CPU the M.2 runs at PCIe 4.0 x4 speeds; with a 10th Gen CPU it drops to PCIe 3.0 x4, halving the theoretical bandwidth.
