i7 920 4ghz how?

The usual...go into the bios, disable things like hardware virtualisation support, SpeedStep (E.I.S.T.), C1E, Execute Disable Bit.

For overclock stable to 3.9GHz:
Set vcore to 1.45V, CPU multiplier to 20x, QPI to 195MHz

The figures above is taken from the Custom PC Issue 072 September 2009, p89, the review of your chosen motherboard tested with a i7 920

If you want 4.0GHz, could try upping the QPI to 200MHz (20x200MHz), but you may need to up the vcore higher to may be 1.5V, which will result in higher temperature. But I'm not a 100% sure if you actually reach 4.0GHz with this board, since the only review I read on it only overclocked it to 3.9GHz, and they said for higher overclock, it would be better to use Asus P6TD Deluxe.

Errrm don't use the above voltages on a D0. Use 1.3v or so and work downwards from there if it's stable.

Also speedstep is useful, I don't see the point in turning it off.

Oh and get a Thermalright Venomous X with 2 fans or a Noctua NH-D14.

or the bundle would be a great starting point for you...

 

[Marine-RX179]

Yes, getting an overclocked bundle would probably be better for you since you have no experience of overclocking.

Only when overclocking. Can put it back on once confirming the system is stable.

Are those voltages not really close to the max voltage allowed on 920's? In this beginner's guide, he explains how to get 4.0GHz relatively easily with a 1.25v Vcore.

Are you referring to C0 chips (as Helios1234 mentioned)?

So if I buy the overclocked bundle is it just a case of sticking in the graphics card and wiring the psu and thats it? or will i still need to go into the bios?

I wondered this. Maybe the bios is just setup.

It comes to £600 if you buy the bundle or £580 if you get the parts seperate

 

[Tiamat21]

really? an extra £20 just for the bundle overclocked?
That is a bit expensive, but maybe worth it am not sure.
Because pre built machines cost about that much extra aswell, thats abit strange.

And ya, the bios settings are saved on the mobo, thats why you just need to plug it all in and play..

 

[LEUVEN]

If it's £20 extra for a "stable" overclock and you've never overclocked before then it's a bargain to let OCUK do it if you consider the amount of hours you could put in getting it stable (allthough thats the appeal to most overclockers)

 

[thevet]

go to the official gigabyte forum or try youtube,you will get loads of info for a succesfull overclock

you can get cookie cutter overclock profiles from all over the net for free , no point paying the extra for a bundle

Yeah especially when every component/build is exactly the same and therefore oc's exactly to the same spec.

you can use pretty much the same settings as someone else aslong as they have the same board as you.

its not like overclocking is hard these days most people can get 3.8 stable without trying.

all the ocuk ones use the same profile from a usb stick anyway and people have posted the settings on teh forum before. use search history save yourself the extra

Custom PC are full of FUD

1.45vcore shuuuuuuuuuuuuuuuuuuuut UUUUUUUUUUUUUUUUUUUUUUUUUp!

 

[easyrider]

Am thinking of ordering this machine and building it but I have never overclocked in my life and just wondering how do you do it can anyone help?

First off you build the system then post in the official i7 overclocking thread and read up and research other peoples settings.

You do some hard work and get the results.

You are probably right...it didn't mention it's D0 stepping so it was probably the old one in that review.

Custom PC are worth wiping my backside on PERIOD
