Much to my wife's dismay, once I get home from work I will be putting on a pot of coffee and begin overclocking. I will not be pushing it too hard, it will mostly be for stability. All specs are in my profile in case you are interested.
Current config: STABLE 22% overclock 2.2Ghz and ram is underclocked bu 30% @ 233mhz. I don't touch the PCI clock because I've never had luck with it
I made this with my cooling method set to "optimal" (actually I can't hear it by normal bases) and stock cooler ! That made me go from ~50 degrees to ~60 degrees in benching mode, so it's cool to do..
I've been overclocking my hd4670 card in the past but now I am not because I see no point

LG-p350/CM_7.2r3+/Android_2.3.7
Stock speed 600mhz clocked at 748mhz seems stable for the most part (again ~25% overclock). I have no control over lotages so that's great for now
I all my experience the best overclock for clockable cpus (like intell ones) stands near 20-25% overclock.
If you I\you need to go more crazy, you need some fine tuning of the voltages, ram, and so... and good cooler should help you as well
That's my point and my experience with overclocking.... I overclock anything if it's stable and don't care about the warrany
Prease give some suggestions or comments and excuse my bad English
I've booted to the windows login screen @ 4.8ghz before. it super unstable though and I've never managed to get CPU-z up because is BSOD's before it completes the login. currently running http://valid.canardpc.com/2648806 rocksolid (ran a 24 hour stress test) and it never got over 53c, idle temps are 35c, or 10c over ambent, with the cooler set to medium speeds. on high it holds at about 30-33c. gets hotter outside in the summer. I've not taken it higher because my motherboard is bottlenecking the amount of wattage I can put into it. RAGE! shoulda bought a better OC'ing board.
