Hello all,

I'm new to manual overclocking (having just used utilities to do it in the past), and I was wondering if there is like a "general rule" for upping the voltage? Like a "When increasing the ratio X amount, increase the voltage Y amount." kind of thing?

What I usually do is set the overclock to the desired multiplier and then use default voltage provided by my motherboard
For example, if the default voltage is setting to 1.30 volts, I will then manually enter in 1.290 volts. Continue lowering the voltage by that amount until the system becomes unstable, then raise so you find the lowest amount of voltage while maintaining system stability
You can test stability by using either prime95 or intel burn test.
Also, don't forget to watch your temps while overclocking

As a general guideline when overclocking - be sure to make notes - tons and tons of notes. Make changes in small increments and test. Once instabilit occurs - step back one or two increments back to stable.

A good strucutred approach to this is critical so that you can recognize the cliff you are approaching before you fall off of it.

As Rule there are things you need to know first. Reading posts and manufactures web sites will reveal what you need to know. You need to know: the Max CPU voltage the chip can handle, the Max Temp the CPU can handle/and temp before it throttles the frequency, the fact you need an aftermarket cooler to enjoy the benefits of OCing.

Ocing takes time and patients. Do not rush as it will effect the outcome! Both posters before me have great advice But they missed one thing, If you change the base clock/reference clock you need to test the ram first as a ram error will show as CPU instability. always check the ram first or you will be running in circles. Use Memtest86+ for 11 passes to be sure the ram is stable then move on to Prime 95 for 5 hours and then Intel Burn Test set to maximum ram for 40 runs. This combination will insure full 24/7 stability after last test is complete. As long as no test errors that is.

to OC the GPU you will still need a program, I use a riva tuner based program myself, and use OCCT on the GPU test with Error Checking enabled to ensure a stable OC there. Do not use OCCT for any other test as it has proven to be unreliable. the only reliable test it has is for the GPU.

leave the PCI clocks alone as there is little it helps with but can make you very unstable.

to your question, NO, there are no set rules, there are many approaches, one of the more popular is figure (read alot) what the max safe voltage is and then see how high you can get within that voltage, then drop a bit and fine tune other settings before advancing higher again and fine tune as you go....pretty much all CPUs are singular, some OC great others are dogs...good backgraound here:
