Hi!

I have this C1E setting in the bios and wanted to know what it does/meens..
I only know that is should be disabled besides EIST when not wanting the CPU to throttle itself down while idle.

Thanks..

EIST Basically drops the multiplier when needing to throttle, C1E drops the FSB. IMO EIST is safer if you need to throttle a chip.

I got it disabled, along with SpeedStep and another setting... Seems pointless to have so many energy saving settings on a desktop unless you leave it on 24/7 and don't do any games.

I turn of C1E and Speedstep, I leave thermal control on, all that does is throttle back the voltage when its not needed, and my clock is stable with the voltage down so it works out nicely.

I say leave it on... I booted to 4.0GHz with it active....savings is savings, and its nothing like C'nQ of the AMD realm.
