I have a laptop with Ryzen 5700U.
As we all know, laptop CPUs usually come with locked voltage. So, traditional undervolting does not work.
I tried the Ryzen Controller software. I set the TDP to 15W. I tried two configurations:
(1) Default 45A max current
(2) Lowest 20A max current
The second config made he CPU run at 2.7GHz, while the first made the CPU run at 2.5GHz at the same power consumption of 15W. I think both of them produced similar amount of heat.
However, the second config's voltage was around 0.9V, while the first config's voltage was around 0.75V.
The reason in desktop, higher voltage damages CPU more is because the current is the same, right?
Is it safe for the voltage to be higher if the current is lower?
Thank you in advance.
