Strange pc energy saving behavior
Hi everyone,
I state that I have always had problems understanding how the energy saving of my Asus laptop works. First of all, I don't understand how energy profiles work and I can't use monitoring tools.
I start from a concrete example:
I'm trying to open a password protected rar archive. I tried various software but then I came across cRARk and its commercial version "parallel password recovery" (PPR) because they are the fastest I have found.
I run cRARk on one of my two GPUs and the demo version of PPR on the CPU using all 4 cores I have. At the same time
To monitor everything I rely on the task manager, "resource monitoring" and GPU-Z.
To change the energy profiles I use the "Windows portable PC center"
The problems are these:
1) The task manager does not report cRARk's GPU usage. So I use GPU-Z.
2) If I select the "Balanced" profile and move the indicator that appears in the panel from "maximum battery life" to "maximum performance" (which is the maximum), GPU-Z brings me the GPU usage back to 90-95 % with (425/933 Mhz GPU / Memory clock), ALWAYS!
So I use the "Energy Saving" profile if I want to reduce fan noise and power consumption during the night. (300/870 MHz)
3) Moving on to the CPU there is the big PROBLEM. If I use the "Balanced" profile in any position the CPU loads at 45% and the frequency is about 1 Ghz (40% from "resource monitoring"). Which is already strange.
If I use the "Energy Saving" profile, the CPU goes to a 65% load and the frequency to 1.6Ghz (66%).
If I use "high performance" it behaves like the "Balanced" profile.
4) My CPU should go beyond 3Ghz but that's another problem!

I wanted to add a question, perhaps this is more feasible:
Is it possible to set the processor frequency to its maximum continuously?
