Ryzen scaling driver

[J89eu]

Hi all

 

How would I go about getting the AMD Ryzen CPU scaling driver? I've had a look around the forum but struggling to find any outright answer. My CPU just sits at the base clock of 3.6GHz currently. 

 

Cheers

If you install the Tips and Tweaks plugin you can choose a CPU Scaling Governor from a menu. "On demand" is the one I use. You can also enable AMD Cool 'n' Quiet in the BIOS.

Hi John

 

I had both of those already enabled but still get the same

 

Thanks

Question 1: did you enable Precision Boost in BIOS?

Question 2: is there actual load on the cores? The scaling only kicks in when there's load (you can pick "Performance" which will kick it up at really low load)

Question 3: how did you check CPU frequency?

I assumed that the OP wants the clocks to scale down when idle or lightly loaded, given that

@J89eu please clarify what behaviour you are expecting to see.

Hi, I will update the thread shortly, cannot reboot as running a parity check!

 

Question 1: did you enable Precision Boost in BIOS? - I am not sure, I will check this

Question 2: is there actual load on the cores? The scaling only kicks in when there's load (you can pick "Performance" which will kick it up at really low load) - Yes, I have been gaming on the VM which has 50% of the cores assigned to it

Question 3: how did you check CPU frequency? On this occasion I checked the VM but perhaps that won't boost the CPU and I should instead be checking via SSH or similar? Would cpufreq-info show this?
