Motherboards

Whether you’re a gaming enthusiast or building a PC purely for work, the Ryzen 3000 series processors will get the job done, and even futureproof your build. These 8-core, 16-thread, processors can handle current-generation (and soon-to-arrive next generation) games with ease, all while having enough octa-core speeds to handle multi-layer rendering applications, and so much more.

Making the choice to build your PC around the Ryzen 3000 series is an easy one to make, but choosing the proper motherboard to house the processor may prove to be a bit trickier. Currently there are three series of motherboards that can handle the Ryzen 7 3700X, and Ryzen 7 3800x, just fine: the B450, X470, and X570 chipset motherboards.

Depending on your budget, and of course the intended use of the device, each of these motherboard chipsets will have viable options. For gaming, all three options can work just fine, so it will ultimately depend on your budget, and whether or not you want to futureproof your PC for the next generation of games. Workstations would be better suited for the X570, as it has compatibility with PCIe 4.0, giving you the ability to use the blazingly-fast 4.0 M.2 SSDs. In terms of ITX cases, both the B450 and X570 motherboards have viable options, again, the budget being the deciding factor.

Other than the price, there are several other aspects that one would have to take into account when shopping for a motherboard; the slightest of details making all the difference. Are you looking to overclock your CPU consistently? Then VRMs are most important. Are you looking to use your computer mainly for gaming? Then 16 GB of RAM will suffice, whereas a workstation would need upwards of 32 GB of RAM support. Also, for workstations, the more the ROM (M.2 and SATA) slots, the better.

Best Motherboards for Ryzen 7 3700X & 3800X Builds – My Recommendations

Best Budget B450 Motherboard for Ryzen 7 3700X & 3800X

If you’re looking for a B450 motherboard, then you most likely want a motherboard on a budget; one that can handle desktop use and current generation games, including competitive online multiplayers. If that’s the case, and you’re looking to build with the Ryzen 7 3700X / 3800X, then the ASRock B450 Fatal1ty Gaming K4 is the B450 motherboard for you.

At under $100, this motherboard has great value. Firstly, despite the price, it is a full-sized ATX board with a respectable VRM solution. It has a virtual 9-phase (6 true) VRM, using SM4337 and SM4336 55A/65A MOSFETs. The heatsink on these VRMs isn’t the greatest, so don’t expect to overclock your processors too much and too often – not that you’ll need to, though, for most tasks.

In terms of RAM, it can hold up to 64 GBs of DDR4 RAM, with up to 3200 MHz OC speeds; more than enough for its intended use. In terms of storage, it has two M.2 PCIe slots: one with up to 2280 support, the other with up to 22110 support. Unfortunately, neither of the two M.2 slots have covers, and using the M.2 slots will disable certain parts of the motherboard. One slot will disable the PCIe x4, while the other will disable two SATA slots. Fortunately, it does come with six SATA 6 GB/s SSD ports (four of which are in 90-degree angles) so you’ll have more than enough slots for storage. It also does have USB 3.1 Gen1 and USB Gen2 Type-A and Type-C ports, so worry not about limited connectivity.

In terms of audio, it comes equipped with a Realtek ALC892 chipset, for 7.1 Channel HD audio; an overall great audio solution for the price.

In fact, its best feature is its price, as this motherboard will only cost you $85; an amazing price for a motherboard that can run Ryzen 3000 series CPUs straight out of the box. A great deal if you’re looking for a motherboard on a budget for the 3700X and 3800X.

Best Value X470 Motherboard for Ryzen 7 3700X & 3800X

The ASUS Crosshair Hero VII is perfect for any overall mid-end Ryzen 7 3700X/3800X setups, be it gaming, workstation or otherwise. It has a 12-phase VRM via an IR35201 PWM controller, using 7 IR3555, 60-amp PowlRstage MOSFETs, and an IR3599 doubler for the 5 CPU VCCs. Overall, this motherboard is great for overclocking either the Ryzen 7 3700X or the Ryzen 7 3800X, as it supplies sufficient voltage and has a respectable heatsink to keep the VRMs from overheating.

It can hold up to 64 GB of DDR4 memory in four slots, with speeds of up to 3600 MHz – sufficient enough for the vast majority of setups, as speeds over 3200 MHz will have diminishing returns, and 64 GB of RAM is more than enough for even most workstation builds – let alone gaming. The ASUS ROG Crosshair VII Hero also has three PCIe slots, two of which are 3.0, and one of which is 2.0. Note that the PCIe x8 will downgrade to x4 if the second M.2 socket is used. Speaking of which, this motherboard can carry up to two M.2 drives (though only one has a heatsink cover) and six SATA SSDs, all being situated in 90-degree angles.

For audio, it comes equipped with the SupremeFX S1220 Codec, with 133dB signal-to-noise ratio on the line-in connection., and includes an ESS Sabre Hi-Fi ES9023P converter and a TI RC4580 op amp for high gain with low distortion.

In terms of software, the Hero VII includes Gamefirst IV, software built for optimizing network traffic in order to enhance gaming internet bandwidth, RAMCache II, which automatically caches your storage devices in order to minimize in-game load times, and of course, Aura Sync, for customizable RGB lighting displays with all ASUS-branded PC gear.

You can currently find the Crosshair VII Hero for $199, which is a great deal for its overall value, be it more than capable of tapping into the Ryzen 7’s 3700X and 3800X power, for high speed gaming setups, and more.

Best Overall X570 Motherboard for Ryzen 7 3700X & 3800X

ASUS took it a step further, and once again released a motherboard worthy of its title of “best overall-value” for its chipset. The ASUS Crosshair Hero VIII, has a 14+2 International Rectifier 3555 PowlRstages, each handling 60 amps of current, accompanied by high-permeability alloy chokes designed to handle up to 45 amps. These VRMs are situated onto a heatsink, which itself connects to an IO via an embedded heatpipe, for overall better heat dispersion. It is clearly designed for giving you all the freedom you need to overclock your CPU as you see fit.

Upping the ante from the AMD Hero VII, this motherboard holds up to 128 GB of DDR4 RAM, and can run speeds of up 4600 MHz. Of course, this upgrade means little for gamers, as 16-32 GBs of RAM, and speeds of 3000-3200 MHz, will more than suffice. Like its predecessor, it comes with two M.2 NVMe slots, though this motherboard supports PCIe 4.0. Also, both M.2s are equipped with aluminum heatsinks this time around. Furthermore, it has eight SATA 6 GB/s SSDs – up two from the Hero VII.

Though having upgraded in terms of VRMs, memory, and storage, the two motherboards have the exact same audio configuration.  Same goes for the RGB displays on the faceplate, which are very similar, and, of course, both come equipped with the same software options.

Though the upgrades from the Hero VII to the Hero VIII are quite significant, they do come at a price: an increase of $179.99 to be exact; the Crosshair Hero VIII being priced at $379.99. If you’re looking to build a high-end gaming setup, then it is well worth the investment, otherwise the Hero VII should work just fine. If you’re looking to build a workstation and want a X570 for the PCIe 4.0 support, check our article here where we analyze the MSI Meg X570 Unify.

Best Budget ITX Motherboard for Ryzen 7 3700X & 3800X

If you’re going for an ITX build, two are our suggestions: one is the above mentioned MSI B450I Gaming Plus AC, the other being Gigabyte’s X570I AORUS Pro WIFI. The latter has similar VRMs, but much better cooling, connectivity, and audio – though it does come at a $55 price increase. If you’re looking for taking full advantage of your CPU, the Gigabyte option would be the way to go. You can read a detailed breakdown of this motherboard in our Ryzen 9 3950X article here.

For its price, the MSI B450I Gaming Plus is the best mITX option for situating a Ryzen 7 3700X or 3800X processor. It uses an Infineon IR35201 PWM controller with a configuration of eight (6 + 2), all-true-phase, Infineon IR3555 60-amp MOSFETs. While this is a powerful VRM solution, the heatsink and general thermal design is not that great, so you will need to have good airflow to prevent overheating, especially if you are looking to overclock the CPU regularly. Same goes for the M.2 slot, which does not have a heatsink/cover.  

The MSI B450I Gaming Plus comes with one PCIe 3.0 x16 slot, and one M.2 NVMe SSD. It can also hold four SATA III SSDs, though note that none of these SSD slots are at 90-degree angles. In regards to RAM it holds up to 64 GB, separated into two slots, of speeds of up to 3466 MHz.

For audio it uses a Realtek ALC887 Codec for 7.1 channel HD audio, with separate PCB layers for left and right audio channels. The audio operates via a dedicated soundcard, being isolated from surrounding circuitry to avoid signal interference.

In regards to software, it comes with MSI’s X-Boost (storage device speed tuning), Command Center (system management), and Live Update which automatically downloads and installs the latest drivers and BIOS updates.

Despite its minor drawbacks, the MSI B450I Gaming Plus AC is the best mITX in the B450 and X470 range, and you can currently find for $165; a great deal if you’re looking for an ITX motherboard on a budget. 

AMD’s high-end Zen 2 processor, the Ryzen 9 3950X, is the most powerful desktop processor currently available in the market. With its 16 cores and 32 threads, this processor is optimized for workstations, but can handle gaming and desktop tasks with ease. Especially for streaming, and content production, this processor is second to none. But a processor is only as good as the motherboard it lays in, for this is the component which gives the CPU the necessary supply power it will need in order to function to its full capacity.

Therefore, to make the most out of the $700+ Ryzen 9 3950X, an X570 motherboard is certainly a must, as anything less would be selling the processor short. Depending on your intended use, there are different key elements to look for when purchasing a motherboard. Firstly, you will want to purchase a motherboard with a VRM solution that covers your overclocking needs, especially if you intend to overclock your CPU often and for extended periods of time.

Next, you’ll want to make sure that the motherboard has enough memory slots for both RAM and ROM, as capacity for RAM, M.2, and SATA SSDs are increasingly important; depending, of course, on your occupation. A great element inherent in X570 motherboards is that they are PCIe 4.0 compatible, meaning you can make use of the newer, blazingly-fast, M.2 PCIe 4.0 SSDs, such as the Sabrent Rocket 4.0. In terms of RAM, if you’re looking to use your computer for production, then you will want upwards of 32 GB of RAM, while if you’re looking to game, stream, and perhaps do some light editing on the side, 16 to 32 GB of RAM will suffice.

Finally, you will want to make sure that the motherboard fits your case, as there are different options out there for EATX, ATX, mATX, and ITX sized motherboards. 

To help you choose your future X570 motherboard, we will present you with the best options depending on intended functionality. Our first choice will be the motherboard best optimized for a gaming setup, next, a motherboard best for workstations, and finally the best motherboard for a small form factor build (mITX); all of which will meet criteria chosen to best maximize the processing power of the strongest AMD CPU: the Ryzen 9 3950X.

All this will, of course, does come at a price: $359 to be exact, which isn’t cheap, but for a high-end gaming setup, and with all the connectivity and features it provides, it is well worth the investment for the perfect gaming motherboard to holster AMD’s Ryzen 9 3950X.

Best Workstation Motherboard for Ryzen 3950X

If you’re looking to build a workstation, then what you really want is functionality. RGB lighting and any related nonessential fluff must be replaced with enhanced performance, in order to fully take advantage of the 16 cores and 32 threads the Ryzen 9 3950X provides – which may currently be overkill for gaming, but is extremely useful for editing videos, images, and other production related workloads. For this intended purpose, the MSI Meg X570 Unify is the perfect match (especially for its price).

The MSI Meg Unify features a 12+2+1 VRM design, with an Infineon IR35201 Digital PWM Controller (6x IR3599, 12x IR3555), and 60-amp power stages on a Dr. MOS design with 12 titanium chokes; ultimately designed for high-power delivery and sustained overclocking. It has a large, all-metal, aluminum extended heatsink cover, which enlarges the surface area and allows for better heat dispersion. In terms of cooling, it also has MSI’s M.2 shield FROZR, for the three M.2 slots it contains, and a FROZR heatsink thermal solution with a built-in fan and AI tuning technology for auto-adjusted fan speeds, all in accordance with the chipset’s temperature fluctuations. It also has a server-grade PCB and a pre-installed I/O cover shield.

In terms of memory, it can hold up to 128GB of DDR4 RAM with up to 5000 (overclocked) MHz speeds. It has three M.2 slots, 2 of which are 2280s, and the other being 22110, and four SATA 6 Gb/s slots.

It uses a 7.1 channel Realtek ALC1220 audio, and an ESS audio DAC, with separated audio layers for left and right channels. What’s really great about this motherboard, in terms of audio, is the dedicated headphone amplifier which auto-detects impedance. This means you can use headphones with up to 600 Ohms of impedance without having to purchase an amplifier.

In terms of other connectivity, is has three PCIe 4.0 x16 slots, two 3.2 Gen 1 (can support up to four) and one 3.2 Gen 2 Type-C USB ports, as well as two USB 2.0 connectors, though it can support up to four.

Considering its $299 price tag, the MSI Meg X570 Unify is an amazingly powerful motherboard with a myriad of features, software options, and convenient work-oriented designs, making it the perfect choice to house the Ryzen 9 3950X at an affordable price.

If you, too, have jumped on the SFF bandwagon, we can’t blame you. It’s great to have such a powerful PC with only a fraction of the footprint, providing you with additional options in regards to displaying your build. The fact that a CPU as powerful as the Ryzen 9 3950X can fit in such a small case, and not lack the ability to overclock to the standards of larger desktop-builds, is a marvel to behold.

For the X570 chipset, two are the mITX motherboards that are in contention: the Gigabyte X570I AORUS Pro WIFI, and the ASUS ROG Strix X570I. Both motherboards have similar VRM performance, similar memory slots, and similar audio output. The ASUS X570I does have a couple of extra USB slots, and an added fan header, though it is questionable whether these are worth the $30-$40 increase in price – hence our choice of Gigabyte’s X570I AORUS Pro WIFI.

This motherboard uses a Direct, all-true, 8-Phase IR35201 PWM controller, with IR3553 40A PowlRstage and Infineon TDA21472, 70-amp, MOSFETs, with no added use of doublers or parallels. This translates to better precision in delivering power to the CPU, in-turn creating better overclocking power and sustainability conditions. Despite its small size, it uses a multilayered extended heatsink, with a LAIRD 1.5mm thick, and 5W/mK thermal conductivity pads – using Fins-Array and direct touch heatpipes to dissipate the heat. It also has an active thermal guard for the M.2 slots; heatsink and fan included in the multilayer deisgn.

In terms of RAM, it can hold up to 64 GBs, separated into two RAM slots, which is standard for its size. It has two PCIe 4.0 M.2 slots, and can hold up to four SATA 6 Gb/s SSDs (all at 90-degree angles).

It uses a Realtek ALC1220-VB codec for 7.1-channel audio, with DSD audio support in the back-panel line out-jack. Similar to the MSI Meg Unify, it can also detect the impedance of your headset to prevent low volumes or distortions in higher impedance headsets.

If you enjoy RGB pizzazz, it does have RGB Fusion 2.0 Software, which you can also use via an app you can install on your phone. It also has Smart Fan 5 software, which limits the use of your fans when the computer is not under heavy loads, a Gigabyte App Center, a portal from where you can choose different utilities such as VTuner, Smart Backup, or SIV, and System Information Viewer, a central location which gives you access to your system’s status. It also has in-Windows apps for fine-tuning your setup, such as EasyTune, allowing you to tweak memory clocks and one-click overclocking, and @BIOS, a tool for updating your BIOS through your operating system.

You can currently find this mITX motherboard for only $219.99, and considering its plethora of features, software, and VRM capabilities, it is certainly a great price to pay for a motherboard that is small in size, but big in performance.

If you’re looking to build a high-end, enthusiast-grade PC right now, the best processor right now to build with is the AMD Ryzen 9 3900X – a 12-core, 24-thread monster of a CPU set to take on Intel’s Core i9-9900KS.

Already proven to be hugely popular, along with the rest of AMD’s new Zen 2 lineup of processors, these CPUs have taken a significant market share away from Intel, and right now show themselves to be the better performance for the price option when compared to Intel. The Ryzen 3000 processors, especially the Ryzen 9 3900X, are sold out practically everywhere and at least for the summer will be difficult to get hold of.

Should you manage to get your hands on the Ryzen 9 3900X, we want to show you how to get the most out of this Zen 2 enthusiast build, and get the absolute best performance from this 7nm processor by pairing it with the best components (example RAM Timings important for Zen 2 builds), with this article focusing on the best motherboards to pair with the Ryzen 9 3900X in 2019.

We will draw from various motherboard options depending on the type of Ryzen 9 3900X build you will be making, such as a budget, mini-ITX, micro-ATX or enthusiast-grade 3900X build.

We will begin this article by choosing the right chipset for the Ryzen 9 3900X, whether to opt for an X570 chipset motherboard or a previous generation X470, B450 or X370 motherboard that also supports the new Zen 2 processors (with a BIOS update using the flashback feature on select motherboards).

X570 vs X470/B450 for Ryzen 9 3900X builds?

On the assumption that PC builders speccing up a build with the Ryzen 9 3900X are looking for a high-performance, next-generation and future proof build – which means we will recommend the new X570 chipset to pair with the Ryzen 9 3900X, rather than a previous generation X470 or B450 motherboard. The reason for this is that the X570 chipset motherboards support Ryzen Zen 2 out of the box, without the need for a BIOS flashback which many builders are experiencing issues with, but the main reason is the support of the new PCIe 4.0 standard, which gives support to the new blazingly fast PCIe 4.0 NVMe SSDs from the likes of Corsair, Sabrent and Patriot. The new PCIe 4.0 SDDs offer speeds of up to 5Gb/s sequential write, far outperforming any PCIe 3.0 NVMe SSD such as the Samsung 970 Evo.

If we were building an enthusiast-level Ryzen 9 3900X focused on maximum performance and utilising the latest technologies in PC gaming, we will want to have a motherboard that supports the PCIe 4.0 standard, and that will be an X570 motherboard for the Ryzen 9 3900X.

With that said, I will now recommend the best motherboards for the Ryzen 9 3900X in 2019 – and if you are set on building with an X470 or B450 motherboard for Ryzen 9 3900X builds, I will also give my recommendations on those further down.

As usual, any questions you may have or want advice on your specific build, let me know in the comment section below!
