Works well with B550-F motherboard and Dell U4021QW monitor8/12/2021 11:44:48 PM
Overall Review: I bought this ThunderboltEX 4 expansion card for use with an ASUS
ROG Strix B550-F Gaming (Wi-Fi) Motherboard and a Dell U4021QW monitor. The monitor only supports its full resolution at 60Hz through DisplayPort and Thunderbolt, and the DisplayPort port was already in use by another device, so I figured I'd get a Thunderbolt expansion card. It's working great for this use case.
Setup is a bit confusing though, and I wish ASUS provided extra details. A key part that's not properly detailed in the ThunderboltEX 4 manual nor the B550-F manual is that you need to go into the BIOS (press DEL during bootup), then to Advanced -> AMD PBS and set the following settings:
- Thunderbolt Support: Enabled
- Thunderbolt Chipset: Maple Ridge
Also, apparently it needs to be in the bottom PCI Express ×4 slot. I'm not sure if this is true or not, it's just something I read in forum posts. On the B550-F, there's two full-size slots, and the top one is usually taken by a graphics card.
Apart from that, follow the rest of the manual (plug in the USB 2.0 and Thunderbolt headers to the motherboard, attach power from your PSU, and install the drivers) and you should be good to go. So far I've only tried video (5120x2160) and USB3 devices, but both are working flawlessly.
Overall Review: I would absolutely recommend this product. You just have to make sure to turn it on in the BIOS and set up the correct BIOS settings. Once you install the supplied driver, you are good to go. Remember that Thunderbolt is not hot swappable, so if you plug in a device you *might* need to restart the machine so the computer recognizes it. But overall very very happy.
