Tips for power management

Can anyone give a novice some tips as what power saving settings should be turned off for nunet? I currently have an overclocked system which shouldn’t go into any power saving states for the cpu and I have turned off the wifi power management to off, and have tuened the screen management to always on. When I run the script, all appears to start to run OK, I use a lot of cpu and ram initially, but after a while it reverts to a small amount of ram and cpu and I get failed tasks?

This happens to everyone a lot, the system is in alpha so it is far from perfect. It may not have to do with your power-save settings
