Best Motherboard for Ryzen 5 5600X and LGA 1151 Guide

This guide covers the best motherboard for Ryzen 5 5600X and the often-confusing LGA 1151 motherboard generations. It links to real boards in our Motherboards collection. We do not print prices because they change; open any product page for the live price.

Best motherboards for the Ryzen 5 5600X

The Ryzen 5 5600X uses the AM4 socket, so every board below is an AM4 board with DDR4 memory. The chipset determines features and how comfortable the BIOS support is.

The 5600X pairs well with B550 or X570 because both chipsets support PCIe 4.0. Older A320, B350 and B450 boards can sometimes run it, but only after a BIOS update, so confirm before you buy. See our processor guide for the other chips that suit these boards.

LGA 1151 motherboard guide: two incompatible generations

LGA 1151 is a confusing socket because two generations share the same shape but are not interchangeable.

A processor from the wrong generation will not start, even though it physically fits. Some 300-series boards also need a BIOS update before a 9th generation chip will boot, so read the board maker's support list.

Other Intel options

• For LGA 1200 (10th and 11th generation) look at the Gigabyte B460M Gaming HD or the Gigabyte H410M H.
• The MSI H81M-E33 is an older LGA 1150 board using DDR3, suited to keeping a legacy system alive.

How to choose a motherboard

1. Start with the processor socket. AM4, LGA 1151 and LGA 1200 are not interchangeable.
2. Match the memory type. Most boards here use DDR4. Our RAM guide explains the difference from DDR3.
3. Pick the size to fit your case. ATX needs a full-size cabinet, while Micro-ATX fits smaller cases.
4. Count the features you need. Check M.2 slots, Wi-Fi, USB ports and display outputs. If you plan an SSD, read the SATA vs NVMe guide.
5. Plan the graphics card. Every board here has a PCIe slot for a graphics card; our graphics card guide helps with the match.

BIOS updates: the step people forget

A motherboard can have the right socket and still refuse a processor if its BIOS is too old. Before buying a processor and board together, open the CPU support page of the board maker and find your processor in the list. Note the minimum BIOS version required. If the board ships with an older version, you may need a compatible older processor or a BIOS flashback feature to update it. Boards marked for Ryzen 5000 in their listings, such as the ASUS TUF Gaming A520M-Plus, are the lowest-risk match for a 5600X.

Frequently asked questions

Which motherboard is best for the Ryzen 5 5600X?

Any AM4 board with a BIOS that supports Ryzen 5000 will work. B550 boards such as the ASUS Prime B550M-K are the usual balanced choice, X570 boards add more features, and A520 boards suit a tighter budget. Check the board maker's CPU support list for the BIOS version required.

Will a B450 or A320 board run a Ryzen 5 5600X?

Possibly, but only after a BIOS update that adds Ryzen 5000 support, and support varies by board model. Check the manufacturer's CPU support list for your exact board before buying, because flashing the BIOS may need an older compatible processor.

Can I use a 9th generation Intel processor on an LGA 1151 board?

Only on a 300-series board such as an H310. A 100 or 200-series board like the B250 supports 6th and 7th generation chips only. Some 300-series boards need a BIOS update before they will start a 9th generation chip.

What is the difference between ATX and Micro-ATX?

ATX boards are larger and offer more expansion slots and ports. Micro-ATX boards are smaller and cheaper and fit both Micro-ATX and ATX cases. Check your case supports the board size you choose.

Do these motherboards use DDR4?

Most listed here use DDR4, but the MSI H81M-E33 on LGA 1150 uses older DDR3. Always confirm the memory type on the product page and match your RAM to it.
