Well, the problem with making an overclocking guide for 1155 CPUs is that all boards are different in how they react with different voltages, and all chips have different limits. That's just how it is. So while I can sit here and preach what works for me and what can theoretically work, it is up to you guys to tweak and see exactly what settings work for you. Overclocking is an art which takes patience and time. Be prepared to crack open your tower and clear the CMOS if it does not boot. I would advise NOT doing any overclocking on the stock cooler.
As far as overclocking Sandy Bridge CPUs, there are only two numbers you have to worry about. Intel has made it stupidly easy, especially on the K series chips.
1. Multiplier
2. VCore
The other settings that you want set to ENABLED are:
1. Load Line Calibration (Under the voltage settings in MIT)
2. CPU Voltage calibrator (or something like that, it's above the turbo options in that BIOS menu)
Before proceeding, make sure you have the latest Chimera installed (1.4.0 or later, found in the downloads section under Chimera), as overclocking via the base multiplier will not work on older versions
To get to the multiplier, enter the BIOS, select Motherboard Intelligent Tweaker (MIT) and then "Advanced frequency settings". From there, set your multiplier to the desired number. (42 is safe for almost any K series chip). Save and reboot.
That is the easiest way to get to 4.2ghz. If you want to go more, however, then you just set the turbo multipliers to higher (I've gotten mine to 5.1ghz, but with higher VCore).
If you up the multiplier past 42, you may start to experience instability. In that case, find the VCore in the BIOS (I believe it is under MIT Voltage settings... it might be under Power Management) and instead of it being set to auto, set it at a value higher than what it is currently set to (which will be in dark blue to the left of the value you can change). Keep upping this until your system is stable and then stress test it with Prime95 or the like.
Watch temperatures however **NOTE: Max for Sandy Bridge CPUs is 95c before they throttle themselves down, however, I try and keep it under 65C load**. I opted to stay at 4.2ghz because it is STUPID FAST anyway at that speed and the voltage is still set to auto, which means it stays within the stock range. I would personally not go over 1.425v for the VCore, as you will see high temperatures and risk damaging the chip over long term with that amount of voltage.
Let me know if you have any questions.

. I have got everything working perfect even all my temps showing down to your guide but i am now trying to over clock and i cant seem to set the multipliers on the cores past 41 is there a reason for this i only want to go to 42 im not really that bothered i just wondered why and does the multiplier at the top still remain at 32x.
