Briefly: Stories of USB connectivity points on AMD X570 and B550 motherboards have circled the boards because the boards’ launch, however the subject has not too long ago come to a head on Reddit. AMD has responded with a easy assertion: they’re unsure what the problem is, and so they’d like to gather extra knowledge.
For the previous few months, studies of sporadic USB disconnections on 500-series motherboards have been stacking up on the desk of AMD’s subreddit. Some customers have reported that their keyboard will out of the blue change into unresponsive for five to 10 seconds, each couple of minutes. Different customers complain that their mouse will decelerate. House owners of sound playing cards are speaking about crackling and distortion.
The strangest factor concerning the subject is that it appears to be new — as a result of X570 and B550 boards aren’t. Whereas the primary complaints have been posted over a 12 months in the past, their frequency appears to have elevated exponentially previously month. Some Redditors not too long ago compiled a statistics desk for customers to share their points and system specs, and it seems like the problem is generally occurring in techniques with new RTX GPUs.
However don’t fear, a flagship GPU isn’t a necessity. A mid vary GPU and some excessive bandwidth units, like exterior arduous drives, exterior seize units, or VR headsets and monitoring stations appear to do the trick simply as effectively. And it’s not simply the excessive bandwidth gadget that can expertise the problem, something related to the identical system may be affected, together with internally related units like CPU coolers — which is a really severe subject.
Some workarounds have been discovered by the group. The primary port of name: turning off “c-states” within the BIOS. It gained’t carry a penalty, and it could possibly halve the frequency of disconnects. But when that doesn’t work, your remaining choices are to change from PCIe 4.0 to PCIe 3.0 or to undergo the BIOS and disable each USB port/header you’re not utilizing. Doing all three will cease the disconnections for most individuals, however not for energy customers. Streamers with a seize card, microphone, webcam, and the same old batch of peripherals are out of luck, mainly.
That’s the place AMD is available in. They’ve requested anybody experiencing points to report them on AMD’s web site. They’ll even be messaging some individuals who’ve commented on their issues on Reddit.
Hopefully, AMD will be capable to resolve these points rapidly with a firmware replace. In the mean time, for brand spanking new system builders, our greatest recommendation is to go for an AMD GPU to pair with X570 and B550 motherboards, as the mixture appears to be virtually devoid of points.
