ASUS PRIME X370-PRO AM4 Motherboard Review

ASUS PRIME X370-PRO AM4 Motherboard Review. Hot on the heels of our  ROG CROSSHAIR VI HERO AM4 Motherboard Review, we now focus on the mid ranged tier, and ASUS has an enticing board, that’s fair on features, and is priced extremely competitive!

Utilizing the AMD X370 chipset, we find support for DDR4 up to 3200Mhz,  M.2 slot, AURA Sync, Xfire and SLI, 5-way optimization and more….

Pricing on the day of review is around 145 UK and the $ 169 99 US

Packaging & Accessories

ASUS reuse a design we’ve seen in the past, with clean black box. From the front side, the emphasis is on the 5-way optimization, and the AURA sync support.

The backside is segmented into sections, that focus on the PRIME’s key features.

Taking a look at the bundle now in no particular order, you’ll find the following:

  • User’s manual
  • 4 x SATA 6Gb/s cable(s)e
  • 1 x Supporting DVD
  • 1 x SLI HB BRIDGE(2-WAY-M)
  • 1 x Q-Connector

For the price point, this is a very generous bundle.

Closer Look

We start our tour with a complete top down view, to absorb what’s on offer. The first impression is good but.. I couldn’t help but notice something, appeared to be missing.

After using the Intel Z170 and Z270 models of the Prime series, in personal rigs of mine. I expected to see the same white shroud and cover, which made those models unique. Sadly it’s not present, and we can only assume this is to keep pricing down.

Despite this, visually it still a nice board, and the silver heatsink looks decent. Not in the same territory as the HERO naturally, but fair considering the price point of the PRIME

The Heatsink over the MOSFETs still produces a unique look, and gives the board a sense of power, and ability

ASUS have reused the same Heatsink over the X370 chipset, that’s we’ve seen in the past. With abstract lines on a mix of white, silver and grays.

The very same styling is carried over and printed directly onto the PCB, particularly around the DDR banks, we like this!

So not the exact look we expected, but the Prime does boast its own feel, and overall it’s a decent looking board. Perhaps a little busy in places.


[PCI-E Setup]

ASUS PRIME X370-PRO AM4 Motherboard Review

ASUS Safe slots have been installed in the first two slots, granting more strength and support for heavier cards. Which is a must these days, for your peace of mind! Your good to go for both AMD Crossfire, or Nvidia SLI here.

I do wish they’d added the extra strength, to the third for the sake of symmetry…a trivial annoyance and not a deal breaker. It is lacking to keep costing down

  • Supports AMD CrossFireX™ Technology


  • AMD Ryzen™ Processors
    2 x PCIe 3.0/2.0 x16 (x16 or dual x8)

[Storage Options]

ASUS have gone for an all SATA approach, avoiding U.2. Instead, offering 8x SATA III 6gbps ports.

Which are all angled for cable neatness.

  • 8 x SATA 6Gb/s port
  • Support Raid 0, 1, 10

[M.2 / U.2]

ASUS PRIME X370-PRO AM4 Motherboard Review

M.2 is the first choice for many, when assembling a new build. The benefits of no cabling, faster speed, and less space required. Drawn many towards M.2 of SATA drives.

While Z270 boards typically boast 2-3 slots, we have only one here. Initially, that felt frustrating, but be realistic and give the matter some more thought. Will you actually need more than one on a budget friendly Ryzen build?

  • AMD Ryzen™ Processors :
    1 x M.2 Socket 3, with M key, type 2242/2260/2280/22110 storage devices support (SATA & PCIE 3.0 x 4 mode)
  • AMD 7th Generation A-series/Athlon™ Processors :
    1 x M.2 Socket 3, with M key, type 2242/2260/2280/22110 storage devices support (SATA & PCIE 3.0 x 2 mode)

[Fan Locations]

ASUS have always provided more than most. The PRIME is another model that follows this trend!

2016 was the year of RGB. like any trend, It’s very much a love-hate snowball, but I must applaud the efforts from ASUS, unlike other brands they been very careful and smart. Lots of thought with how and where they apply the actual lighting, on most of their products.

ASUS PRIME X370-PRO AM4 Motherboard Review

When implemented correctly the end results can be impressive.  The RGB here is somewhat basic, relying on a single area, that cast’s an ambient light down the left side. 

That said, the PRIME does boast an RGB header, so adding your own strip lighting would be the logical choice


Keep in mind these scored are listed in minutes, the actual difference between each is almost zero


Before launch, as reported widely DDR4 support and stability was troublesome, this has since been addressed with BIOS updates, and we ran at 3000Mhz with no issue. As with previous testing the gaps between each board are small.

[GAMING 1080P]

Its been no secret, many publications have reported lower than anticipated 1080P results, and our finding echoes exactly that. AMD has since published, with time for changes to roll out, with enchantments to compilers and software to catch up; these numbers will improve across the board.
