    • The best I've ever seen/used
Best motherboard I've ever seen or used. It's simply awe inspiring when you boot up for the first time! high stability, updates itself with armor crate and handles anything you throw at it! You simply cant go wrong with this board for a TRX40 AMD cpu. Yes, it's expensive, but worth every penny, if your using a high end threadripper, like the Ryzen 3970x or 3990x. It's now been nearly 30 days since upgrading my PC with this board among other components. I have had Zero issues so far. it's been very stable. Only issue I've had is trying to update the BIOS with Armory Crate and the BIOS saying its not a proper BIOS file. It's possible I already have the latest BIOS and i am sitting here trying to update a file thats already updated. Either way it runs great, I was just trying to update to the latest update. ... show more

    • not for the faint of heart
This board is meant for very powerful threadripper systems and it delivers on the power. However, it takes a lot of wrestling to optimize it. Onboard cpu TPM was causing stuttering and blue screens, a known ryzen issue. I thought they solved this problem in software/windows update, but the stuttering returned, so I use a discrete tpm chip without stuttering. . This board does not reboot smoothly. That is its only flaw. I solved the problem temporarily by overvolting ram but that did not end well. I am giving it 5 stars anyway because my pc is so fast and so beautiful. I am stably running anywhere from 8% to 18 overclock of my 3970x threadripper, and overclocking my rtx 3090 so much so that i am in the top gpu results (#5 in the UK) of sisoft sandra 2021. Plus the looks of this motherboard are simply unbeatable, with an led strip going down the edge of the motherboard that changes color and syncs with the fans, etc. its plain nuts. ... show more

    • Overpriced Trash
1. After a couple of weeks of use, the onboard 10-gigabit NIC died. It no longer negotiated a link, no matter what I plugged into it. It’s made by Aquantia, so I wasn’t surprised. I didn’t want to rip out the board to do an RMA, so I put an Intel PCIe 10-gigabit NIC in the system. I’ve never had one of those die, unlike the trash from Aquantia, which I’ve had many problems with. 2. The ASMedia SATA controller is garbage. If you reboot the system, the BIOS won’t detect drives attached to it. You have to power down the system, then power it back on. Once on, the controller occasionally resets the ports attached to it, causing IO errors. The board has eight SATA ports. Four go TRX40 chipset and work fine. The other four go to the ASMedia controller and are very unreliable. I had to hook up my extra SATA drives to my LSI RAID controller because basic tasks (installing an OS, booting, mounting drives) was too unreliable with the ASMedia ports. 3. You get the same technical support from ASUS as a budget builder. Despite costing more than most ASUS workstation motherboards, you get the same level of support with this board that you get with a $90 board. If you choose a cheaper ASUS workstation board, you get pro support. 4. The ASUS ROG forum sucks. I tried to register and had to wait to be approved for weeks. Despite being run by ASUS employees, apparently getting their customers help is not one of their priorities. 5. The BIOS lacks many features. So, despite costing more than ASUS workstation boards, this board’s BIOS has fewer features. I initially installed two GPUs in the system, but the BIOS doesn’t let you choose a primary GPU. The wrong GPU took over the display, making PCIe passthrough to a VM impossible. The BIOS also doesn’t let you manage boot entries. If you want to delete stale entries, you have to boot into an OS and use a tool within the OS. 6. Despite Threadripper CPUs supporting 72 PCIe lanes, this board only has four PCIe slots. 7. There’s no serial header on the motherboard. 8. The system takes forever to do a cold boot. This is more of an issue with Threadripper than this board though. I bought this because I wanted the best. But this isn’t the best – just the most expensive. I probably should have gotten an ASUS WS C422 SAGE as it has two 10-gigabit onboard Intel ports and costs $150 less. ... show more

    • Painless
Put this MB together with a 32 core threadripper, 4 NVME drives and a Nvidia 2080 ti in Fractal R6 case for PIX 4d image processing. Simple setup compared with other systems I've built. No issues thus far. Cut our image processing time down 4x from our previous intel system. OLED is a nice touch for any troubleshooting showing post messages etc.. however, not not needed in my case. ... show more

    • Rock solid
I have two of these boards, plus one non-alpha version. Use it with 3990X and 3970X, 256GB of 3600MHz RAM. All three boards been rock solid, not a single problem under both Windows and Ubuntu. This has been one of the best experiences I've had with top of the line Asus boards, which has not always been the case. One think I want to mention is that I use water cooling using EK monoblock which covers CPU and VRM. Have not seen CPU temperatures ever reaching 60C no matter the load. That monoblock is doing a great job and I can highly recommend it. ... show more
