If you are planning to do some overclocking with a Ivy Bridge based processor, you are so much better off with a K model processor. Why K versions you ask? Well, the default non-K processors will be much harder to overclock. With Nehalem/Clarkdale (1st generation Core i3/i5/i7) pretty much you take your base clock of 133 MHz and apply say a default multiplier of 25, that would be your 3.33 GHz processor. That base clock was capable of going so much higher, 150, 186 and when tweaked right, even over 200 MHz. So if you were able to apply a fictive 175 MHz on your base clock, you could multiply it with the limited 25 multiplier. That would get you 4375 MHz.
The new technology however has an embedded GPU / video processor merged into the very same processor die running over the same bus sharing the same L3 cache memory, things got increasingly complicated in matters of tweaking.
The new 100 MHz baseclock of Sandy/Ivy Bridge processors are harder to tweak, if you are lucky you can get 110 MHz out of it with regular cooling, multiply that with your maximum multiplier and you'll notice that the default processor can only overclock a few hundred MHz at best. And that is why Intel introduced the K series, since it offers you an unlocked multiplier which will allow you to go much, much higher.
So please do get a 20 USD more expensive K version and you'll have much better tweaking options in the BIOS. With a proper motherboard you can now set a multiplier per core.
The procedure is as follows:
If optional, increase/release the TDP limit of your processor to 200~250 Watts
And now set the TURBO multiplier at a maximum of your liking, we applied an MP of 48 on all four cores
You can also disable the Turbo multiplier all together and simply increase the system multiplier
Increase CPU voltage, though setting AUTO might work fine, we applied 1.35V
Make sure your processor is properly cooled (we used a Noctua D12 heatpipe cooler and forced the fan to 60% RPM)
Save and Exit BIOS / UEFI
So these settings the processor can turbo any or all cores towards that multiplier of 48 times that 100 MHz baseclock frequency, that's a 4800 MHz configuration setup in less than a minute.
This entire overclock will be integrated into the test sessions. So all benchmarks will have these overclocked results embedded into our article. The K editions are going to kick ass and absolutely will offer the most bang for buck, to the enthusiast crowd of course. BTW have a look at the temps and get REALLY scared. That's a heavy duty dual fan Noctua D14 in use right there.
