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.

See CPU Power states - http://en.wikipedia.org/wiki/Advanced_Configuration_and... and http://www.intel.com/support/processors/sb/cs-028739.ht... and a white paper on C-States http://download.intel.com/design/processor/applnots/320...

disable turbo boot but and yes have the other settings enabled..
they are power saving features.

no that glitch about Giggle-Byte, never heard of that nonsense.
I have had Giggles AMD and Intel and overclocked on both.


Why disable the turbo boost?

might deem your clock unstable if you go for a higher overclock.
it's unpredictable and when you think your stable and gaming or benching it kicks in and blue screen or freeze.

not planing on over clockin it...kinda pointless since im already building another i7 rig

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.

so now your thinking about overclocking the new rig huh.?
change of mind I see or giving it some thought...

that's funny. :sarcastic: 

if i can i push it a lil bit without having to change any of my components i will if i'll have to get a new cooler i like it the way it is

It all depends on the heat, anything above ~4GHz you need an aftermarket HSF. For the $ to Performance the $20 CM Hyper 212 Plus is the best or $35 CM Hyper 212 EVO.

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.

My specs are:
GA-B75M-HD3
