editing dvfs table in script.fex

random426

Hi, I was editing dvfs table to downclock my orange pi PC, to reduce temperatures and power consumption.
I came across two lines that read:

pmu_level0 = 11300
pmu_level1 = 576 (or pmu_level1 = 1100 on some other script.fex files)

can someone explain what they do and how should I edit them when changing voltages.

Thanks.

I tried the value 1100 and it worked ok.
I will share some info about my personal solution if anyone else stumbles upon this thread.

the folowing sections differ in certain script.fex files. I decided to go with versions that have lower frequencies and voltages. (taken from https://raw.githubusercontent.co ... g/h3/orange_pi2.fex)

note that I just copied the values and do not fully understand all of them so use at your discretion

in adition to this i also changed the line "dram_clk"  to  600, but i dont think this one is doing its job.

I have observed that in the world the present day, video games are classified as the latest rage with children of all ages. There are times when it may be unattainable to drag the kids away from the games. If you want the best of both worlds, there are plenty of educational activities for kids.

Aw, that was a really top quality post. In theory I’d like to write like this too – taking time and also real effort to make a excellent article… but what can I say… I procrastinate alot and also by no means seem to get something done.        a course in miracles
