AMD releases BIOS update for Ryzen boost bug

Hardware specialist AMD has issued and updated BIOS to fix Ryzen boost bug.

In a blog update on its community website, the company said the new update would add 25MHz to 50MHz boost clock speed. However, the improvements won’t be released for at least three weeks.

Last week the tech giant acknowledged its firmware was having an issue that reduced boost frequency. A survey conducted by Youtuber Der8aeur found that only 5.6 per cent of users could reach advertised clock speeds for AMD’s flagship Ryzen 9 3900.

“Starting with our commitment to provide you an update on processor boost, our analysis indicates that the processor boost algorithm was affected by an issue that could cause target frequencies to be lower than expected. This has been resolved,” the chip specialist said.

“We’ve also been exploring other opportunities to optimize performance, which can further enhance the frequency. These changes are now being implemented in flashable BIOSes from our motherboard partners.

“Across the stack of third Gen Ryzen Processors, our internal testing shows that these changes can add approximately 25-50MHz to the current boost frequencies under various workloads.

On top of fixing the boost bug, AMD has revisited what it calls calmer idle. The tech giant is releasing an update to prevent the processors from going into its overclock boost mode for small applications. This saves boost increase for when it’s really needed.

“Today we’re announcing that AGESA 1003ABBA carries firmware-level changes designed to do just that,”said AMD.

“The changes primarily arrive in the form of an “activity filter” that empowers the CPU boost algorithm itself to disregard intermittent OS and application background noise. Example test cases might include video playback, game launchers, monitoring utilities, and peripheral utilities.

“These cases tend to make regular requests for a higher boost state, but their intermittent nature would fall below the threshold of the activity filter.

“Net-net, we expect you’ll see lower desktop voltages, around 1.2V, for the core(s) actively handling such tasks. We believe this solution will be even more effective than the July changes for an even wider range of applications.”
