How We Test

Introducing The 570X (again)

The MSI X399 Carbon used our Thermaltake F51 Suppressor case, but ASRock's X399 Taichi gets to live its review life cycle inside the Corsair 570X, our new X399 test chassis. This case screams sex appeal, with tempered glass on four sides and three prominent 120mm LED fans in front with room to fit either 360mm or 240mm radiators for liquid cooling.

Since it is a review rig, we’ll be moving components in and out quite a bit, so the rubber pads for the glass standoffs have started to erode. Dust isn’t too much of a concern for us, but there are plenty of gaps throughout the glass joints, so we’ll keep a can of compressed air handy. As lovely as this case is, it is a chore keeping my kids from streaking their greasy little hands all over those pretty blue lights.

Another new addition to the bench is the Elgato HD60 Pro. We’re not currently testing it right now, but we intended to have some streaming benchmarks (and of course, hours of streaming with PlayerUnknown’s Battlegrounds). Plus, it gives us another reason to put cool hardware into a PCIe slot.

As for the remaining components, no other changes to our rig. Antec’s 1200W High Current power supply provides the juice to our Gigabyte GTX 1080 G1 Gaming GPU and Ryzen Threadripper 1950X. G.Skill provides the 32GB of DDR4-3200MHz RAM, and Toshiba still supports all of our motherboard reviewers with its 256GB RD400 M.2 NVMe drive. Fractal Design’s Celcius S36 360mm water cooler is placed into the intake side of our chassis to provide cooling for our 190W processor.

We're sticking with our LG 4K display. 1080p data is useful in some instances, but it'd be wasteful paired with all of this sweet hardware. We will provide 1080p and 4K data for gaming benchmarks, and we are using 4K as our standard desktop resolution unless otherwise noted. If requested, we can provide 1440p as well in future articles.

We do have to make some changes and tweaks to our normal motherboard testing methodology for the X399 platform. For starters, some of the software in our suite does not support the plethora of cores available. As such, we have to deactivate resources in some instances and bypass certain features in others. These changes will be listed in the benchmarking results section, but we will be consistent from a test methodology perspective.

One Threadripper-specific feature that we covered in Paul Alcorn's CPU reviews is the use of Game Mode versus Creator mode. If I’m buying X399, I want all of my resources, regardless of the gaming penalties. Both modes will be tested in the benchmarks for the sake of this comparison, but moving forward we will only test with Creator Mode enabled.

    Pretty nice for the price. ??

    I have one with a TR1950X. Other than there being vast pages of UEFI settings with useless or no labels whatsoever, and the fact that you cannot disable the wireless card (can disable the radio, but the card still shows up in device manager) its pretty much all I could ask for. Especially since the ASUS, GB, and MSI boards in this price range all seemingly were very touchy with certain ram,

    This may seem like an odd request, but could you use Microsoft's USBView to pull up the Host controller info for this board? I have an ASRock Z87 Extreme9a/c board that has been a great board until recently. Windows began complaining that it didn't have enough USB resources when I plugged my xbox controller in a couple weeks ago. I don't think I have an abnormally large amount of USB devices, but I do have a few. Keyboard, Mouse, G13, Bluetooth, Headset, Card Reader, Vive, Aquaero, the case front panel hub and 2 monitor hubs. Plunging in the xbox controller sends it off the cliff. The Z87 E9 motherboard has 2 built in USB2 controllers and 1 USB3 controller, but all of the user accessible ports are mapped to the USB3 controller. And since Intel for some reason artificially limited the Z87 to only 92 of the 128 possible connections, it doesn't take much to exceed the limits. I had to buy an add-in USB3 board to keep my devices plugged in. So I'm looking to see if all the ports are allocated to one controller or if they are spread out across a couple.

    JCAULLEY, it might be worth slinging this question to the Discord channel. I've dismantled this board as I continue testing X399, but I'm working on a custom X399 build that I might throw the Taichi in. I haven't decided.
  • jcaulley_74
    Thanks for responding, I figured it was a long shot anyways. Maybe you can consider taking a couple minutes in your future reviews to look at the USB allocation. A quick google search shows that this is not a rare problem at least. The Vive by itself consumes more than 30 endpoints and puts a serious dent in the USB budget. It's a really quick check and may (or may not) show more differentiation in boards.

    Jeez, what does it take for this to get Editor's Approval? Those seem like pretty meaningless cons
  • MadOver
    True that. I guess they had to write something...

    It's hard to award a product an Editor Choice award without testing more than 2 products. We're getting there, but if we award everything that's inexpensive then the award won't mean anything. I've only given out 1 other Editor Choice award, so it means something if it gets it.
