i7 powersave, safe to turn off?

I have a laptop with an 8-core i7. i7z shows a lot of activity for C6. If I wanted to turn off all powersave, can I do so, and is it safe for the hardware?

Note that all cpu freq scaling is already disabled in kernel.

i'm not in front of my i7 to really answer but i think the cpu use c6 to activate intel turbo by looking c6 state of its cores
a bit like if core0 is busy and other are sleeping, increase mhz of core0

You may have a BIOS option to disable powersave features. Or do you mean, manually from like a menu?

I would think that as long as you have adequate cooling to run wide open the whole time, you should be able to do so. I'm not sure I understand why you would want to though. There's a significant difference in the amount of power needed between modes.
