a while back i enabled c3/c6 support.....no idea why i did it so dun ask! anyway,whats the point of that option i mean ....what does it do also ive read on countless posts that it should be enabled with trubo boost,but a friend told me its glitched somehow on gigabyte mobos...can anyone explain the c3/c6 state support and wether or not i should i enable it ? and is it realy glitched some how on the gigabyte mobos and slows down everything? thanks alot in advance

There are only a few reasons to Disable any C-States: 1. Overclocking (Enabled is to prevent Vdroop dropouts but not a problem if the clock speed is fixed) or 2. The CPU needs to be in a full power mode 24/7, or others etc.
As far as 'glitches' IDK maybe the Gigabyte's power management is poorly done or monitored by the BIOS and is causing some issues. Often a BIOS update helps 'System Stability' updates.
Bottom-line, the best (usable) OC's have all of the C-States Enabled versus the (useless / bench ) OC's where all of the C-States are Disabled with the CPU at a fixed clock.
in this case it is since all it will do is cost me more money and i wont be using it for anything other than downloading and watching movies and playin some old games which the computer atm is kinda an overkill for
Fully usable OC with ALL C-States Enabled, my CPU runs from 1.2GHz to 4.8GHz, and it sleeps/wakes and performs like 'Stock' but faster - http://valid.canardpc.com/show_oc.php?id=2320509 Some of my SQL compile testing can take 20 minutes to a few hours so a reduction of 20%~50% with a few settings of the BIOS is well worth the efforts. However, if I'm not going to be needing OC then I can simply boot to the BIOS and within 45 seconds be running Stock or OC; BIOS Profiles. None of my OC's has C-States Disabled.
IMO $20 if nothing more than just to mess around is worth the small price, and in the meantime IF your work, mine does, justifies OC'ing then use the OC Profile when needed. The worst case is your CPU will run cooler and last a little longer.
