Re: Thread: How much can I overclock an AMD Athlon II Regor 3.0Ghz CPU?
With those little dual cores you shouldn't have any problems pushing it up to 3.6 or 3.8.
I was able to get mine up to 3.6 on a board with 3 chokes total (which is horribly insufficient).
On any decent midrange board you should be able to push those up close to 4ghz or more.
If the games you're playing are already slow then you'll see a decent improvement. I think most newer games are more GPU dependant than anything else.
It's mostly the fact that your chip is 2 cores that is limiting you I think. In single or dual threaded apps or games your chip should do just fine keeping up, but when you go to open WoW, PS2 emu, Wii emu, 3 web browsers, and Coretemp (this is just an example) your system is going to choke.
To get any sort of decent increase in performance you'll have to overclock that thing to at least 3.4ghz+, and to do that you'll need to play with the FSB (I don't know what the **** they call it these days, it's stock 200mhz on AMD chips though).
If you're using a budget board you're not going to be able to raise the FSB much without issues, and you have to remember that when overclocking via FSB that the memory controller, HT link, and memory are ALL going to increase in frequency as the FSB increases.
To prevent memory bottlenecking you be sure to reduce it at least 1 step before you overclock. Increasing vNB a bit will help as well, and don't rush! Take it 5mhz at a time until you reach the point of instability, and then work from there by either increasing CPU voltage a bit, increasing vNB a bit, or reducing memory timings, or frequency.
