I've had a weird system-wide stutter for months and the usual googling and troubleshooting didn't help.. omg. This might be it. Thank you Linus and thank you op.
I had it on my Windows 11 PC for a long time. I use this PC for music production and it was infuriating - the sound would just cut out intermittently like the computer couldn't keep up. I tried lots of things, including an expensive CPU upgrade. In the end Asus released a new BIOS for the motherboard to address this AMD stutter, and that fixed it.
I don't really know anything about that. Currently HWiNFO64 shows Microcode Update Revision A201025 and SMU Firmware Revision 56.74.0. I don't know whether those are the numbers you're asking for, or what they were while it was still having problems.
