Disclaimer:

-Overclocking will void any warrenties with Intel/AMD.

Guidelines to follow for a safe and sucessful overclock on your Intel/AMD system:

1. Increase the multiplier by .5 (100 MHz) at a time; after test the stability for 20-30 min.
2. Know the safe heat and voltage limite for your CPU.
3. Do not increase FSB ratio and Multiplier at the same time.
4. Monitor heat and core activity while stress testing the computer.
5. Make a safety net by setting temperature limits on Corsair Link.
6. All CPU's are different so dont expect the same results as someone else.
7. When increasing the FSB ratio make sure NB, SB, and ram all have their voltages locked in to the recommended voltage. Having the voltage set to auto will harm the components.
8. DO NOT overclock the GPU or RAM while increasing the FSB ratio.


Cooling:

1. The best fan set up has a few well placed fans that maximize how quick air is moved in and out.
2. Static pressure fans are used with intake/radiators and Airflow fans are used as exhaust. (i only use Noctua industrial static pressure fans^*1.)
3. Things that will disrupt the current are; cables, storage, DIMM, AIO's, GPU's, and poorly placed fans.
4. When choosing liquid closed loop systems look here: http://www.tomshardware.com/reviews/best-cpu-coolers,4181-2.html
5. Radiators provide the best results set as intake in a push/pull configuration.

Programs^*2:

-Userbenchmark- Benchmarks components.
-CPU-Z- Validates the Overclock.
-HWMonitor- Monitors computer components.
-Prime95- Tests computers stability.
-Corsair Link- I use this as a safety net. The program allows the user to set the max temp allowed for all components and will shut down the device if a certain temperature is reached.

Notes:

-FSB Ratio overclocking^*3 (is not recommended for beginners) increases the clock of all the components in the computer! (Yes even the GPU clock is increased by the FSB ratio.) The FSB ratio works best in increments of 4. DO NOT increase any other component after increasing the ratio until the system has booted and been tested. Finally when comparing my results with multiplier overclocking to FSB overclocking I find that the FSB ratio increases the over all performance more than the multiplier would at the same frequency.

-CPU Multiplier increases the CPU clock speed and goes up or down in increments of .5 which in turn will increase or decrease the speed by 100 MHz

-Heat kills instantly volts do not but do keep in mind + volts = + heat.

-Make sure when setting a new clock that the components are monitored closely. I cannot stress this enough.




1.* Scythe fans are also very good.

2.* Those are the programs I like.

3.* FSB Ratio overclocking requires knowledge on overclocking CPU, RAM, NB, SB, and GPU.




As i write this prime95 is running in the background testing a new clock.

Latest bench

-http://www.userbenchmark.com/UserRun/3599786 - Keep in mind my ram is being compared to Intel user's. (AMD's FX series CPU's have a poorly designed architecture so the RAM is not used to its maximum potential.)

I prefer and do use OCCT, RealTemp GT, memtest, CPU-Z and Furmark. High end air coolers like a Cryorig R1. With water cooling I always mount it in the top of the case blowing out I have never been a fan of blowing warm/hot air into the PC.

For your Prime 95 you cant just use any version.
 
It's not just for any Processor. many have very limited possibilities. Not all motherboards are good for OC some almost none at all.
Also worth mentioning is that raising FSB/BCLK also raises RAM and PCIe frequencies which can have impact on stability.
First thing when considering OC is to ensure proper cooling of processor and whole case and in case of higher OC, added cooling of NB/chipset and VRM also has to be addressed. As Zerk said, prime 95 is not ideal test and one has to carefully chose which test and with which offsets and that's even more acute when using on AMD systems. OCCT is more adjustable and provides other data at same time that can be followed and checked afterwards even in case of lockups.
Another first is to set everything in BIOS on manual, even when you leave those values at default. Turning off all power saving and turbo options at least until OC is finalized helps testing so it doesn't get confused by them and also helps stability.
Never do more than one of things at a time unless you already tested limits of that part.

Just thinking why does overclocking void it warranty? Surely if Intel make a cpu that is meant for overclocking I.e k chips then they have to honour sometype of warranty. Also they sell them with description turbo mode blah blah. Its like selling a umberalla and say you cant get it wet and if u do it voids the warranty

In notes i explain what fsb ratio overclocking is and how it increases all the clock rates on the motherboard not just the CPU. 3.* is also another note on FSB ratio overclocking
