Enjoying some \"OC Juice\" south of the border...not advised
To some, overclocking is a superfluous and trivial. To others, it's a hobby. Some say it's an art and I'd say they're probably right. Still, to most of us out there, it's a necessity. It's in our human nature really. Humans, for the most part, like to bring out the best in things--to pursue excellence, to get the best "bang for the buck", which is essentially what overclocking is all about. The ancient Greeks came up with the cardinal virtues. Adam Smith expounded upon the "invisible hand" and the role of the free market in his book The Wealth of Nations. Victor Maslow put it at the top of his hierarchy of needs as "self-actualization". All these things inform us that overclocking, at its heart, is really nothing new, but rather a new expression of what it means to be fully human.
That being said, overclocking just like anything else worthwhile (i.e. becoming a virtuous person), takes practice and perseverence. For those reading this that are willing to make this investment, I encourage you to read on. For those of you who are not, I send you back to your insipid lives of mediocrity.
Step I: Start with quality hardware
A prerequisite to successful overclocking is quality hardware. A good PSU, motherboard (from Gigabyte of course), and RAM (from OCZ of course) are all necessary to do any sort of real overclocking.
Step II: the OC Juice!!!
To begin any overclocking endeavor, I have to begin by selecting a suitable "OC Juice". This usually takes the form of a malted wheat or barley beverage with some hops in it (refer to picture). I find one or two OC juices in my system really helps with the relaxation, mental dexterity, and "out-of-of-the-box" thinking necessary for a successful OC venture. For those of you who aren't of legal age, a caffeinated drink might do for a second-place substitute.
Regardless, selecting a good OC juice is important. You may want to keep in mind the possibility of needing to add it to your liquid cooling loop, should an emergency come up. With this in mind, certain beverages have better thermal properties than others. Dark (sometimes labeled dŁnkel) and amber ales are not very suitable. Pilsners and lighter beers are generally better, however, you should not be deceived by beverages that have the word 'Ice' or 'Frost' in them (i.e. Natural Ice, Bud Ice, Smirnoff Ice, or the Frost brewed liner tagline). This is solely a marketing ploy and will not necessarily lead to better thermal properties. Do not sacrifice bad taste for one of these marketing ploys. On the extreme of bad taste, though, I have found that Natural Light makes a decent coolant due to the fact that it shares many properties with common anti-freeze. I find wheat beers, such as Blue Moon, or Boulevard Wheat to be pretty good on all accounts.
**Note: in the picture you may discern the label "Negra Modelo" and mistakenly infer that this is an OC Juice of choice. First off, it's a dark beer. Also, if you look further you will see clues that indicate this photo was taken south of the border meaning equatorial ambient temperatures which are not suitable for overclocking.**
Step III: Find a cool environment
It's a no brainer, but you shouldn't be trying to overclock in a hot place. Heat = bad. Not only should the environment be cool temperature-wise, but you should also feel comfortable and relaxed in it, and it should inspire you to greatness. Maybe a poster of a team of kayakers approaching a waterfall with some inspirational saying below it would help out. It's all about you here.
Step IV: Crank up the voltage!!!
Here's where the OC begins. Crank up the voltage in your motherboard's bios to your max comfort level, given your hardware, OC conditions, cooling solution, and OC juice selection/consumption level. You will go about attaining the max clock speeds based on this voltage level.
Step V: Tweak clock speeds
Start experimenting with bus frequency and multiplier settings until your clock becomes unstable under torture testing with a program like Prime 95, then back them down to the last stable settings. Here, you may benefit from researching forums and reviews to find out what others have attained with similar hardware, voltage levels and cooling. This can be a point of reference.
Step VI: Tweak memory speeds
When finding max CPU clock, it's best to keep memory at lower speeds with loose timings. After you find your max CPU clock, then you can tweak memory speeds and tighten up the timings. It's best to isolate the OC variables and approach them one at a time. Again, keep testing to find out what works and what doesn't.
Step VII: Finalize testing and admire results
This is where the reward comes in. After you've achieved stability you're OC work is done. Admire your work and enjoy the added efficiency/bragging rights your work has entitled you to. This is also where you could crack open another OC juice in celebration.
So there you have it. While this is just a cursory guide, I hope it inspires you to learn more and push the envelope with your hardware and above all, over clock your way to being a better person.

|Very dangerous to tell OC Novices to mess with Core voltages when overclocking, its not that simple.|
It takes a lot of research, and not something to do lightly. Make sure you know the Voltage limits that the CPU has before even looking at doing any overclocking. In correctly done and you can cause irreparable damage ( or fry your CPU with the amount of heat you generate from increasing voltage). You must use a program like Core Temps to see the real CPU temperatures whilst stress testing to see if the Voltage increase has not resulted in uncontrollable heat build up. Make sure you know the thermal limits of your CPU also some can handle higher temps then others.
Becareful with setting Core Voltage to Auto, as the Motherboard has a tendency to use more voltage then is absolutely necessary. Use as a guide (check using CPUZ etc) what the Auto Voltage is whilst using Stress programs (Prime 95) then go down from there one step at a time until u reach the voltage that causes Prime to crash, then use the Voltage above that level (test prime for a few hours on each step down on the voltage to be sure that the voltage is sufficient)
i Know that anything above 1.35v on an i7 is getting in the danger area. Above this and Air cooling will struggle to control the heat so better cooling methods are required (water cooling or better), again Search the internet and you will learn from others success and failures. I use the Thermal Right Ultra extreme for my cooler with dual Sunon highspeed fans in push pull config for the optimum cooling, have toyed with the idea of water cooling but for now it is sufficient.
Secondly OC should recommended using after market cooling. The more you pay for it the better the performance (Generally). Again research the best Heat sink for your needs and budget.
I use Asus Motherboards becuase of there usually Rock solid. My friend with a high end Gigabyte MB could not get the same OC on his i7 920 as i could on my cheaper Asus board (he has trouble Overclocking to 4.2ghz comfortably whereas i have it prime tested and running safely) This is because Asus doesn't have Vdrop like the Gigabyte board (Checked using CPUZ program and watched the core voltage fluctuate whereas the Asus stayed at the desired voltage). He had to set his Core Voltage to 1.385+ volts whereas i could comfortably set mine to 1.325volts, might sound like small difference but that extra bit of voltage increases Temperatures dramatically. He ended up getting the same board i did.
I personally use Corsair RAM and it has no problems OC but there are many good brands out there for memory that can fit a persons needs and budget.
I OC to see the absolute limits the CPU can handle and then go back to stock until that power is needed, so i know that i have that much extra power at my disposable with out reducing the life of the CPU by keeping it Overclocked all the time
I managed 4.2ghz stable on Prime on my Intel core i7 920 but cant get over this with out passing into dangerous Voltage territory.
i know this is a simple guide but just pointing out the things that might cause people grief when OCing for the first time
