Max boost degraded after a silly mistake on Ryzen 7 7840U

Hi community, I have something for you that is not an issue per se, just an interesting thing to discuss and investigate. I have a Framework 13 AMD with an AMD Ryzen 7 7840U. Initially, the tools that report the max boost of the CPU like neofetch, fastfetch, or Zenmonitor3 show that the CPU could boost to the 5.1 GHz that AMD says it can boost. But I made a silly mistake, I was very annoyed by the spikes on fan speed that the default fan curve has and I installed fw-fanctrl to personalize the fan curve. Long story short this tool was not reading the temperature correctly from the CPU and it was running very hot until I figured out that the CPU was throttling and the chassis very hot. I just disabled the tool and let the bios manage the fan curve but now the CPU can’t do the max boost to 5.1 GHz only goes to 4.35 GHz and tools like fastfetch also report that as the max boost. For example, see this screenshot from Zenmonitor3:

Do you think that I have permanently degraded the CPU? There is a way to restore the previous max boost. Thanks!

This frequency seems to be like power profiles daemon set to power saver. Set to balanced or performance

I some cases disable might not work, try uninstalling.

Unplug the USBC PD charging, shutdown the laptop, wait 10 seconds, start up the laptop. This could clear the custom fan curve.

Hi @Charlie_6, thanks for answer. I double check that when I disable the tool the fan was again managed by the BIOS because the annoying spikes return, and the temps go down. But just in case I remove the tool and did the power off with the USBC PD disconnected, etc., and nothing, no matter the power profile that I have selected, my max boost is 4.35 GHz now…

Did you measure the actual frequency (not the “ideal” frequency in neofetch) before using the fw-fanctrl? Compare these values. AFAIK the 4.35GHz is the instantaneous boost on all cores, single core boost is higher, 5.1 instantaneous and 4.6 continuous

I didn’t make rigorous measurements at that time, I have a widget on the desktop that shows the max clock and I saw spikes that match the original value that I remember well that I saw the first time that I installed the machine. However, I did not pay a lot of attention at that time (I do not record a profile of measurements). Now I never see that big spikes and the new value in tools like neofetch and fastfetch is too different to pass unnoticed…

Someone with an Framework 13 AMD with an AMD Ryzen 7 7840U can execute cpupower frequency-info and share the output. I’m putting mine here. Thanks!

I find this very strange, as the default cpufreq governor should be powersave instead of performance, and your current CPU frequency is exactly at base speed, this also wastes energy when idling.

During single-core boost, most other cores are underclocked, hence the “powersave” to enable that single core to boost to max speed, at least for a short time.

What’s your current OS? What’s your power management, TLP or PPD? AFAIK the amd-pstate-epp should be set to active, the cpufreq govenror should be set to powersave and the energy_performance_preference should be set to either balance-power or balance-performance

I don’t think that the default profile has something to see with this problem. My default profile is balanced see:

I think this is could be a protection at firmware level or something that if you stress thermally the CPU they will low the pstate_max_freq for future protection in case of an sufficient thermal solution, I just want to revert that because is not the case. Unless is a kind of physical fuse and then I’m screw… Maybe flashing an old bios and upgrading again… or maybe just accept the fact that I lost a little bit of performance…

Try resetting the BIOS

In that case, contact support if within warranty, if not, go to a board level repair shop and replace/resolder the fuse

Hi @Charlie_6, just to let you know that I reset the bios, but that did not do the trick, then I installed Windows 11 on another drive and I could easily see the CPU boosting over 4.3 GHz. Then I did a clean install and now I’m seeing the original values again. It seems that there was a wrong software configuration in someplace. I will pay more attention now to see if it happens again. Thanks!

Great! Glad to hear it’s not a physical problem

FWIW there is a kernel bug that prevents max boost on the Phoenix or Hawk PointAPUs in kernel 6.9. It’s going to be fixed in 6.10-rc1 and will come to 6.9.y. If you want to apply it to your kernel now here is the patch.

Hi @Mario_Limonciello, I can confirm now that the Kernel 6.9 was the issue. I’m going back to 6.6 LTS until 6.10 is released in the stable channel. Thanks for let me know, have a nice day…

You don’t need to wait for 6.10, you can take the single parch to 6.9 or 6.9.2 will probably pick it up.

I also found that the unsafe_shutdown in SSD has been increasing rapidly (once or twice per shutdown/suspend) since very recently. Is this have something to do with kernel 6.9?

I’m not aware of this, but I don’t follow nvme subsystem very closely. If you can reproduce on 6.9 but not 6.8 then it might be worth a bisect.

Mario, I love how active you are on this forum, and how helpful your responses are. Thanks for the link!
