Rules of thumb for general ocing

I was wondering if there are mathematical formulas or equations that will help me estimate safe zones and avoid danger zones before I actually start changing settings? In my specs below I will be changing out the mobo to an Asus Crosshair III ROG mobo (AM3) for the sole purpose of overclocking. Also general rules of thumb when ocing a Phenom II 955, my ram and my 4870's? And I would also appreciate some suggestions regarding oc software (temp monitoring, settings changes etc.). My os is win7x64 and its stable. Been running it for about 5 or 6 mo's now without a crash. Thank you for your help, I know I ask alot. And if I'm asking too much in a single post, lemme know how to do this right as I am new at forum posting as well. And thank you Overclockersclub!

My Overclocking Basics guide may be the type of thing you're looking for. It's old, but it should still have the basic concepts in there.

 

Also, as far as maximum voltages, you don't really need to do any calculations to find those out. If you just read some of the posts in the Overclocking and Cooling and Processors, Motherboards and Memory forums (especially ones with PhenomII quads like your own) you'll see how high most people take their voltages. Otherwise you can just plainly ask. I don't have one of these chips so I don't know the accepted max voltages for them, but I bet others here could tell you. (There's not going to be one exact figure that everyone uses, but usually there's an accepted range.)

As Verran said, you should read as much as you can about your cpu and MB, but that cpu of yours can take up to 1.5v (as safe voltage). I don't know what your using as a cpu cooler, but if your using the stock one that came with your cpu, I would highly recommend getting a very good quality aftermarket cpu cooler, before you start OC'ing!

 

Always keep an eye on your cpu temp! Best program to use is Real Temp, it's free

Plus CPUZ (another free one), gives you voltages, memory speeds and timings......

 

For OC'ing your system I would first try upping your multiplier, from 16 to 17....reboot, do a stress test, like the OCCT stress test, Prime95, Intel BurnIn.....and see if it's stable at a higher multiplier, and as said earlier, especially when stress testing, keep an eye on your cpu temps!!! Once you start seeing 60c to 65c, then it's time to stop OC'ing!

 

But really, do all the reading before OC'ing!

It's just the smart thing to do!

I have just ordered tha Zalman CNPS9900LED 120mm 2 Ball CPU Cooler. Will this cooler qualify for an oc rig? Is there a better one that won't break the bank? thanks for your help so far and I'm allready using cpuz and I wanted to post a screenshot of my current settings for you but I can't seem to figure that one out either. Dumb right?
