General overclocking

[Cavallino]

Hello folks.

So I purchased a 4770k a few months ago which I am absolutely loving.

I have dabbled a little with the overclocking in Windows, and noticed that overclocking a 4770k seems a little different compared to a Q6600.

For example

The 4770k runs at 100 x 35 I think...

I remember my Q6600 running at 400 X 8 = 3.2GHz.

So how does the multiplier/FSB system work on the 4770k compared to that of the older Q6600?

Basically I want to overclock the CPU to 4.5GHz, so should I apply a permanent overclock or would it be better to apply it as a boost/turbo (not sure what is the name of the feature) so that its used as and when needed?

You just increase the multiplier, so in your example above it would result in a 3.5Ghz clock speed so you increase the multiplier (35) to say 40 and that would then result in a 4GHz clock speed.

Thanks, understand that.

But where in the Bios should I change this? Should this be changed on the core multiplier or is there another option to apply this to the "turbo" multiplier?


Also how come the Q6600 FSB is 400 but on this 4770k its 100?

Core multiplier is the one you want. This will then "over rule" the turbo frequency.

FSB values are probably different due to how the chip works (I'm sure someone will give a very detailed explanation shortly)

I still have a Q6600 system in use and I find it confusing when I play with the overclock seeing FSB of 400!

Most motherboards have something like speedstep which will reduce your multiplier at idle anyway so you'll only run your max OC when it's needed to reduce power consumption.

So is it better to have the CPU permanently overclocked or only via speedstep?

Power saving features are something you can enable or disable down to your personal preference.

Pretty sure I have my CPU clocked all the time and disabled all the power saving features. I want the full horsepower at all times

Completely up to you!

If you only use your PC for a few hours a day then power saving will not make a diff. If you leave it on 24/7 though, you can save a few quid over a long period.
