But is it actually running on 4.0? You should switch to 3.0 if your bios has the option.
It is. There's nothing preventing it other than intentionally not supporting it. BIOSes briefly supported that before AMD mandated to turn it off on B450 but depending on your BIOS version you might still have the option. When I got my 3700X my launch BIOS supported it and I switched it to 3.0 since I had a 5700XT which is 4.0.
Wait, it's fixed with a simple powered hub plugged in to the X570 ports rather than an add-in board with a different USB chipset?
That's what several people on the G2 reddit recommended, and it worked like a charm in my case.
In my case, this issue is actually made worse by plugging the devices into a powered usb hub funnily enough. It drags everything down in the hub down when it happens.
Yes, that's what happened to me apparently as well!
This sounds like a power supply issue more than anything else tbh
Yep same. I was one of the lucky few who got a 3080 on launch, and since they're like gold dust even now there was no information back then about the problems. I tried everything. Swapped multiple PC parts (PSU/RAM), starting fresh on a new windows install, tried all the USB jacks as well as using usb hubs etc, messed with power options/drivers etc, messed with loads of bios options including voltages under the assumption the IF was unstable and so much more that I can't even remember at this point. I was even close to sending the 3080 back via RMA for a replacement, literally had it boxed up with the courier scheduled to come pick it up, until I happened across some threads from last years Navi cards which mentioned very similar issues with the solution being to drop to Gen 3.
I was actually about to order a 3600 and B550 mobo when this crept up as an acknowledged issue.
I just wouldn't worry about it. It seems this is something like a signal integrity / tolerances issue which affects only a small number of people, so first off there's a good chance you won't be affected at all with any motherboard. Like you say, everyone has been going AMD for their gaming PCs for maybe a year or two now, and yet there isn't a great deal of noise about this. Maybe it is only certain motherboards (doesn't seem like it, to me), but I don't think there is any solid data yet. If you are affected, just turn off PCIe 4.0 to your GPU? It provides very little benefit of note anyway, and it's not like you can get a PCIe 4.0 system from Intel anyway... Or if you really want PCIe 4.0 on your GPU, and your system is affected by this bug - try the workaround of using a powered USB hub, a ~$30 fix (and possibly a useful thing to have anyway). If that doesn't work, fit a PCIe USB add-in card, again a ~$30 fix - which should certainly solve the issue no matter what. I guess if you weren't planning to otherwise, get a full size board with some spare PCIe slots just in case.
