Hi @Viciouss
I had similar error because of UEFI+SecureBoot mode:
# sudo dmesg | grep -e secureboot -e amdctl
[ 0.000000] secureboot: Secure boot enabled
[ 0.014819] secureboot: Secure boot enabled
[85917.978818] Lockdown: amdctl: raw MSR access is restricted; see man kernel_lockdown.7
Legacy BIOS mode works fine for me. Does it help?
Hey @AYuusuke
That did the trick, thank you very much!
Hi,
I wanted to undervolt the 5300G in my homelab but no matter what I try, I always get:
ERROR: Could not write data to /dev/cpu/0/msr
msr module is loaded, I tried both the -m cli option as well as the sys fs parameter. I'm using kernel 6.4.6 currently. Output of -g is:
cat /proc/cpuinfo:
Any help is appreciated.
Kind Regards Martin
