    I pored over Reddit trying to find a solution and found nothing conclusive. Not only that, but I can't find anything as to AMD confirming or admitting the problem. If you have post that says all of that, then link to it here, otherwise it did...

    Update: I had to go to call my CC bank and initiate a dispute so that I can get my money back for the defective CPU. A few days after that, AMD's store (apparently run by Digital River) caved and sent me a return label. I would suggest not...

    I wonder if this is related at all to the substrate problems hitting the markets, I know there are shortages and they might be trying to stretch what is available. Digitimes was reporting back in January that the PS5 chips were experiencing...

    To be 100% sure about the CPU, I swapped the 3900X into my other B550 Mortar that has been running perfectly for months. I also used a Hyper 212 cooler instead of the eSports Duo. Of course it didn't help. The resets began around 34 minutes...

    No one is talking about WiFi interference here. Why are you even bringing that up? It makes no sense. This is not something new with AGESA. It's not a software bug. Some Ryzens have defective USB. I have a defective 3900X. I swap a good...

    What I've gathered is that only the USB ports that come from my 3900X are the ones that are seriously affected. Yet the CPU USB ports on my 3600X on the same motherboard work fine. This is why I am fairly confident the 3900X is defective...

    More details? Exactly what makes you suspicious that I might be lying or intentionally omitting details? Maybe there are more details because I have wasted more time and money trying to solve this. And now I'm wasting more time replying to...

    It's the CPUs. I tried: MSI B550M Mortar (two of them), MSI B550M PRO VDH, and an ASUS X570-Plus TUF. All have the exact same problem. It's also not software, drivers, or OS. Linux and Windows both have the same problem. You're just lucky...

    Absolutely nothing you do will fix this problem. The best I've gotten was get the USB 2.0 (chipset ports) working okay by setting the chipset PCIe to Gen 2. People who say they've fixed the problem by disabling C-states, setting idle power...

    I dont know if this applies to your situation, but back when I had a 1700 on a B350, I had all kinds of weird USB issues. I found that increasing the Soc voltage 0.05V (or perhaps it was 0.1V) via offset, removed the problems. The 3900x is a...

    Yeah, see if it still happens after resetting your BIOS to defaults, and if so, if adding voltage fixes it. May be a poor sample on your CPU. Also for your headless home servers, have you heard of PiKVM? I just found out about this project...

    Keep in mind, the Ryzen 9 3900X has a USB controller integrated into it. There could be an issue with that controller. Make sure your Infinity Fabric clock isn't set too high either. That can cause all sorts of issues.

    Dan, I suspected that it might have the USB built it, but I wasn't sure. Make sense. But aren't these CPUs guaranteed to work at 1800Mhz Infinity Fabric? Schizo, I'm running everything at default now (2666Mhz RAM and 1333Mhz IF) and I thought...

    Hi. Thanks for the suggestion. I'm using an MSI B550M Mortar and it doesn't have that option anywhere in the BIOS.

    It's definitely a problem when the CPU is loaded. I will try disabling some core to see if that helps. I don't know if there is a motherboard problem or I got a defective CPU. Sensor data at 100% load. Voltages look okay to me...

    Dr.Nut replied to the thread Ryzen 3900X USB Reset Problem.
    That's the thing, it's a headless server with no GPU installed. I'll put a GPU in, enter the BIOS, and force PCIe to Gen3 where ever possible. I think the problem occurs when the CPU is loaded. I just ran it for a while unloaded and there...

    I updated to the latest BIOS, set the CPU and RAM frequencies and voltages. Plugged in a single USB stick and keyboard and still getting resets. This time I tried the Gen 2 ports. So it looks like this problem affects all of the ports. [Sat...

    I've been running Linux on a couple of 3600Xs @4.3ghz 24/7 since October of last year and they've been working perfectly. I was so impressed by them that I decided to upgrade one to 3900X since the 5000 series is hard to get and not worth the...
