rob356 Posted January 13, 2008 Share Posted January 13, 2008 I have searched around google, and found that all but the core 2 extreme is unlocked, so upping the clock speed is out. I have a New 20" iMac, 2.0GHz. I would like to SAFELY overclock it. I have never overclocked before, but I know there are risks involved, overheating etc. Seeing as the iMac is tiny, I can't up it too much, if it is possible. So my question, is it possible, if so how? Link to comment Share on other sites More sharing options...
Lactobacillus P Posted January 13, 2008 Share Posted January 13, 2008 Well with all the heat issues iMacs have I wouldn't recommend overclocking - the speed increase will hardly be noticable below 20% but the heat and the instability will!

Alessandro17 Posted January 13, 2008 Share Posted January 13, 2008 It has already been discussed: don't do it. Overclocking an iMac is very much loke overclocking a laptop, something that you don't do. If you can add RAM, that is the best performance improvement your iMac can get. Being OS X a *nix OS, it will take more advantage from added RAM than it would from an overclocked CPU. Link to comment Share on other sites More sharing options...

rob356 Posted January 13, 2008 Author Share Posted January 13, 2008 okay well, thanks anyway. RAM is cheap anyway. Link to comment Share on other sites More sharing options...
