ASUS have 5 new AM4 motherboards for the Ryzen lineup. The Asus ROG Crosshair VI Hero is the most popular and is the high-end model. ASUS have a great reputation for producing top quality gaming components and this motherboard is no different. Even the budget AM4 boards produced by ASUS are high quality. Crosshair VI Hero supports overclocking, like all other Ryzen motherboards on this page. The Asus Pro Clock technology though will work in conjunction with ASUS TurboV processing unit to allow a solid overclock with your processor cooler. For those looking to OC their memory then this board will allow you to overclock it to an eye-watering 3200MHz!

When it comes to audio the VI Hero comes locked and loaded with the SupremeFX S1220 Codec which us arguably one of the best audio chips at this price for gamers. The technical talk; The chip gives you an 113dB signal-to-noise ratio, 120dB line out and 7.1 channel playback. Add some custom fan grills, SLI Bridge and even more. As a side note, ASUS also have tutorials and downloads available for 3D printer users, so you can customise various parts of your Mobo.

As an overall opinion, we consider the Asus ROG Crosshair VI Hero to be THE best AM4 and X370 motherboard for gaming. This takes into account the expansion slots, connectivity, OC RAM, great Audio and of course the affordable pricing. This is a great motherboard option if you’re looking to upgrade to Ryzen 7 or 5. If you have the budget then I would class this as great value for money.

If I were looking for a Ryzen motherboard on a budget then the GIGABYTE GA-AB350 Gaming 3 is the one I would choose. Actually, I have it in my basket for a budget Ryzen build I am doing at the moment!

The ONLY issue I have read and seen is supported. In the early days, there were some support issues with RAM not working at the correct speeds etc. By the looks of it, those issues are being dealt with in BIOS updates and I am seeing fewer issues by the week. With this in mind, this was the same for every Ryzen motherboard, not just this model. Gigabyte and ASUS seem to be well on top of the issues with other manufacturers releasing fixes too. If you are concerned then do what we do, locate the verified list of RAM modules which are supported for each motherboard. These can be found on the GIGABYTE GA-AB350 Gaming 3 webpage.

So, let’s get into why you should choose the GIGABYTE GA-AB350 Gaming 3. You get everything you would expect from Gigabyte with the high-quality build, customer support, a community of users for feedback. Not to mention the M.2 support, CrossFire, 64GB RAM @ 3200MHz (OC) and the reliably good ALC1220 Realtek audio chipset.

Asus Prime B350-Plus

Asus Prime B350-Plus

Motherboard: Asus Prime B350-Plus
Socket: AM4
Chipset: X370
Form Factor: ATX
Release Year: 2017
CPU Support: Ryzen 5 & 7
Expansion Slots: 6 PCIe, 6 SATA, 2 M.2
RAM: Slots 4 x DDR4

CrossFire Support: Yes

The ASUS Prime B350 Plus can usually be found around the $100 mark. If you are looking for a budget AM4 B350 motherboard with overclocking, RAM overclocking and 6 PCIe slots with CrossFire support then the Asus Prime B350 Plus is your best option. The board itself has the ability to overclock your Ryzen CPU as far as possible, providing your cooler will allow good cooling.

It should be noted that when a B350 board is used in CrossFire then both PCIe 3.0 lanes will revert from x16 to x8, usually not a point of contention but worth footnote. That being said, if you’re looking for the GTX equivalent and want an SLI option then your only options are X370 Chipsets.

Overall the Asus Prime B350-Plus is one of the best budget motherboards. It doesn’t come with the newest and best features but it is more than enough for the casual gamer.

What is the difference between X370, B350 & A320 Chipsets

Both the X370 and B350 are the “main” Ryzen motherboards that most of us will be looking to purchase. Even AMD classify these boards as Enthusiast and Mainstream. Why is that? Overclocking and connectivity. Both of these chipsets offer the most connectivity options and also support Overclocking. Given all CPUs are overclockable then it makes perfect sense that the best Ryzen motherboard should support overclocking. In other words, if you want to use your CPU to its best ability then you really need to be looking for an X370 or B350 solution.

The “main” difference between X370 and B350 can be either game breaking or minor, depending on your budget and computer use. The main difference that gamers might find is dual GPUs. Only the X370 can support SLI and CrossFire will revert PCIe lanes to x8 from the original x16.

What Ryzen CPUs can AM4 motherboards support?

This is a question we have seen being asked a lot, so I have decided to answer it here. All of them. The Ryzen lineup is supported by all X370 and B350, actually, all AM4 motherboards support the new CPU. So if you have a Ryzen 7 1800, 1700X, 1700, Ryzen 5 1600X, 1600, 1500X or even a 1400 CPU then you are covered! (Phew…).
