Turbo boost and speed step

[Perturabo]

Hi guys,

Ive just finished putting together a rig for my little brother and have been playing around trying to get a nice OC on it.

The board is a gigabyte Ga-Z77x-D3H and the processor is a 3570K.

My experience of overclocking has been entirely on older chips and so there are a few settings on here I am not so used to. So first off I just disabled all the power saving stuff, c states, speed step etc and disabled turbo boost to remove possible complications. OCing managed to get everything stable at 4.5 GHz @ 1.16 V and 4.8 GHz @ 1.2 V without any problems, ratio and Vcore both locked.

But then I started thinking that he is going to be using this rig for everyday stuff and gaming, not folding or anything so he doesnt need his processor running full tilt all the time and running up his electricity bill

So getting to the point of this thread....Can I use speed step and turbo boost to have a situation where the overclock will only apply when he needs it but the system remain stable? I am slightly cautious about letting the computer take control of voltages as my experience with auto overclocking etc in the past has been generally bad.

If anyone can enlighten me on how to approach this I would appreciate it, im happy with overclocking in general just not these two features.

Cheers guys.

to be honest 1.2volts for a 4.8 OC isn't going to be using that much power is it? Also that seems like insanely low voltage for such an overclock or is that because it is one of the 3570k processors

 

[Perturabo]

No its not going to insanely power hungry I dont think but I am a bit of a perfectionist and if it can be improved then I would like to do it, besides learning new things is always good

Yes I thought that was an insanely low voltage too but I guess I hit it lucky with the chip...I did have to play around with LLC and PLL to get it stable but in the end it got there.

i dont think speedstep and turboboost change voltage much at all, AFAIK it only changes the multiplier

I did previously have a low overclock which would kick in when needed by leaving c3 speedstep an all that on but it was no where near as stable as i have it now on a 24/7 oc

 

[Perturabo]

Thats a shame, I have had a play around myself and from what I have done it does seem less stable like you say. The Bios in particular really doesnt seem to like it and freezes constantly.

You can overclock the cpu on the turbo. Thats what i am going to do. Btw you got very nice clocks/low vcore on that chip. Deffo a silicon lottery winner

 

[Perturabo]

Cheers man, yeah this chip seems like a complete beast! its a shame its my brother's and not mine

I might keep trying with the turbo overclock, but at the same volts I had it at before it is completely unstable. Im not sure if it is something to do with this bios though as there are loads of people having similar bios freeze ups on this mobo. I shall persevere and see where I get.

If you do want to overclock but have the most power efficiency you could overclock using offset voltage rather than a fixed manual voltage? It can be more of a pain to work out your stable voltage but you do get all the power saving and speedstepping advantages of the base setup with less needing to be altered.

 

[Perturabo]

This is what I was thinking also but when I go into the Bios the option (DVID in the case of this bios) is greyed out and unavailable. Looking around the internet it appears that this bios doesn't support offest voltage for some strange reason. I must say the more I use it the less I like this Bios, its a nightmare :S

Another option might be to set up clock profiles? It's not as sexy as having automatic OCing or turbo but you can select a different profile when you need the extra power or even underclock it if you are just browsing the web.
