I currently have my Intel Core i7-3770K at 4.2 GHz with the stock cooling. I ordered the Corsair Hydro Series™ H110 on amazon.com yesterday and I'm most definetely going to get it till Friday, next week! Which are the highest clock speeds I can overclock my CPU to, without having to change the voltages? I have one golden rule which is to never touch the voltages, no matter what, so that's why I want to keep the stock voltages.

More about : intel core 3770k

Probably 4.2Ghz. That's about as high as you can go on stock voltage no matter what cooling you have. Maybe 4.3Ghz if you have a very good chip.

Every cpu is different. Some will OC without any voltage tweaking while others require a significant increase just to obtain a slight OC.

A lot will depend on your motherboard as well.

A "normal" OC on IB is considered 4.0 - 4.5 but not everyone can obtain a 4.5 either.

I'll still say you'll be in the 4.0 - 4.5 range without adding voltage. You should be fine with your motherboard selection (it's quality). It's really down to the luck of the draw with your cpu, the quality of your cooler and how hot you're willing to let it run. You could be bound by what the cpu will allow - you could be bound by how well your cooler cools it.

It's a lot like playing the lottery.

It will be amazing if I can hit 4.6 GHz with the stock voltages! I am not worried about my Corsair Hydro Series™ H110 water cooling system, because it's one of the best and judging by this web site: http://www.guru3d.com/articles_pages/corsair_h110_revie... , my CPU should run with a temperature of 29 C while Idle and 62 C while being 100% loaded, considering that it runs at 4.6 GHz!

I'm running 4.7 on 1.25v with my i5-3470k - I feel VERY lucky to be able to do this. The i7 does seem to OC a little better from what I've seen.

However I'm running a full custom water system and I'm seeing 33C at idle and 70C max on an 8 hour Prime95 run. Most games run at about 63C on the worst core.

I am going to get Radeon HD 7990, so it's going to be a good thing if I can overclock to 4.6 GHz! My Intel Core i7-3770K is a little bit slower than the Radeon HD 7990, if it runs at stock clocks!
