[Hardware]AMD responds to USB problems: it will affect your GPU and CPU

[WilkerCSBD]

Although we have been repeating the same mantra with USB for almost two years and the problems that we have endured with the X570 chipset (not to mention other bizarre ones that we have had), it has only been 15 days that AMD has recognized that they exist. Now and after a selective study of what happened, they offer the first solutions and surely many users will not like it at all, especially because they affect the performance of the GPU and PCIe, or the power of the processor.

Report after report, step by step, so has the course of the conference for AMD and the successive errors that various chipsets and motherboard models present, specifically and to be exact, X570 and B550. Reddit had to arrive and a specific branch within this forum for AMD to put the batteries and now we have the first statements and "corrections" about what happened.

The amount of data flowing could be the trigger

Although we do not suffer this as a problem, since the USB disconnection occurs at each restart and sporadically, the data obtained by AMD begins to draw a more or less concrete scenario. To be specific, to the already combination of chipsets it is added that they are normally linked with an NVIDIA RTX 3000 and also with some high bandwidth device (unspecified).

Therefore, and based on the indications that AMD has given, we could perfectly think that the problems come from a high amount of data that runs through various buses and poor power management of its controllers. But so that you can draw your own conclusions on the matter, AMD has released the following fixes:

Verify that your motherboard is updated to the latest BIOS version and configured with factory default / optimized settings. Check your motherboard manufacturer's website for instructions on how to download and update your motherboard.
Check if your Windows 10 has the latest version installed and is fully up to date. For information on how to update Windows 10, see Microsoft's article: Update Windows 10.
Make sure the AMD Ryzen chipset driver is installed and up to date. The latest driver for the Ryzen chipset is 2.13.27.501 and can be downloaded here.
And if that fails, then "consider using any of the following solutions:"

Set the PCIe mode from Gen4 / Auto to Gen 3 in BIOS.
Disable global C states in BIOS.

As we say, this may help certain users if their problems are in Windows, but in the vast majority of cases the problems come from turning on the computer, where the USB has no power. Similarly, AMD has stated that its engineering team is actively investigating the issue and with high priority.

But the problem has been active for so long and the solutions are so strange, that there have already been some users who have contacted AMD to make a disbursement of their CPU, to which the company has flatly refused, opening more gap with those who suffer this nuisance. Losing PCIe bandwidth and with it performance in the NVIDIA RTX 3000 is a solution? Does keeping the CPU at maximum frequency and / or voltage fix something?

AMD has a lot of work to do here and these solutions sound more like a wild excuse than anything else. Is there a problem with the PCIe 4.0 bus and its controller built into the CPU? We will be on the lookout for all these AMD issues with USBs.
