reducing heat

I am trying to reduce the power usage and heat for a specific applications. I am only using one of the ethernet ports, and no wifi. Also, I am trying to reduce the CPU clock so it only does what I need.

In this forum there is information about how to do it:
mmio 0x1000003c 0x03040201

Is the mems command (included in the firmware) and mmio the same? It doesn't seem to be working.

I also tried this blog entry:

Turning off all the unused ethernet ports. I don't really see any decrease in current.

I am exploring a couple more possibilities and maybe somebody has already tried it:

1. Using a lower input voltage than 5V. Would that reduce heat?
2. Using ffmpeg instead of mjpeg_streamer. ffmpeg might be lighter considering the lack of a web server.

That register is for old vocore version with RT5350 core, can not use for vocore2.
in firmware we have a command named mem inside.
