OC AMD Phenom 965 BE

So, I am new to overclocking, well cpus at least. I OC my gpu to 900 mhz but Im assuming cpus arent that easy. I was wondering how I should approach this with the asus M5A97 mobo. I am looking to OC to 4 GHz hopefully because of my cpu bottlenecking future gpu upgrades. Im going to be getting a Hyper 212 evo cooler. I am looking for any help/tips/opinion of that happening.

Its quite simple to overclock it. But making sure its stable might take some time.Since your CPU is unlocked, you will just have to increase the multiplier in the BIOS.

Increase the speed step by step until your system doesn't POST (reset your BIOS to continue by removing the battery for 10 seconds). You've then reached the limit of what you can do without...

Increase the speed step by step until your system doesn't POST (reset your BIOS to continue by removing the battery for 10 seconds). You've then reached the limit of what you can do without increasing the voltage. Once you've increased the voltage, the heat output will get serious, but you will easily be able to go over 4 GHz.

You will also need to test if the system is stable when you increase the speed. Use Prime95 Blend test and RealTemp or HWMonitor to watch the temperatures. If the Prime95 test stops, then its unstable. If it gets too hot, the CPU will throttle.

Thanks for the help, It seems like it works similar to my gpu OC since its unlocked. Increase speeds until it becomes unstable and lower it slightly to make it stable. Would I be able to overclock now with the stock cooler running 45C idle without too much heat? Same for increasing the voltage, would I be able to get to 4 GHz without the voltage increase? I know it varies from cpu to cpu but your best guess?

You should not try to overclock on the stock cooler at all. You won't have any problems when the CPU is idling. But the temperature will to the 80°C+ when under load. And that's not so good.

And reaching 4 GHz with stock voltages is a bit stretching it. You might reach it, but again, if you are overclocking this much, you should think about a good cooler first. The Hyper 212 Evo is a great option.
