A guide for overclocking

[Phenomenal Flea]

Hey again!

So, I successfully overclocked my CPU up to 3.2, 3.4 and 3.5. However I didn't feel like I was getting much of a speed boost at all. In fact, I began thinking that it was going slower. Then again this could be because of a number of things, such as the fact that I had plugged in my Wiimote via Bluetooth or because I changed revision.

Also, I'm unsure as to whether the temperature could have also been a factor. I just really hope it's not slow because I damaged it, perhaps through heat. In Madworld, I was getting a heatwave effect with cut outs of where objects used to be in the last frames. This also seemed to be apparent in Super Mario Sunshine, too.

Then again, I never did find the PCI/e setting you were talking about so perhaps that's why I didn't notice much of a difference. Would that most likely be the reason why?

One last thing, I found the option to increase my CPU voltage and I read that I Could manage 3.7GHz if I increase it. Would that be a sensible idea?

Thanks!

EDIT: There seems to be a increase of each part (t1, t2, t3 and core) of around 2-6C difference after playing Dolphin. The biggest difference is my GPU which jumps from 38C to 53C, that scares me. Although it seems to be inconsistent seeing as other times the difference was 9C or 12C. Still, is this concerning or is this normal of a GPU?
Thanks!
