I have a Mayhem G3 eclipse XT notebook. I decided to use ATItool to get a slight overclock for my GPU (it's a mobile x1600).
The stock core was at 446 Mhz, I was able to up it to 531 Mhz artifact free.
The memory is at 450 Mhz, but everytime the automated "maximun finder" adjusts the frequency my monitor blinks, thats not good is it?

As of now, I have no means to monitor temps or adjust fan speed (even though I have a lap cooler if that helps)
 
blinking is relaively normal, it should stop once it finds the max speed. ;)

and there's no thermal monitoring in the drivers? that surprises me...

I've looked for thermals, but came up short.
 
Update: the mem max finder raised the frequency to 600 Mhz... then all of a sudden massive artifacts attack the screen. I quickly abort the finder and I try to tone the freq down but my comp crashed to a black screen. Everything seems fine now, but I'm manually adjusting it from now on.
 
try around 550mhz and see how well that works... keep in mind that increased heat from ram will decrease max core clock ;)

I did not know that. 525/525 seems to work, anything higher and artifacts attack.
 
Due to thermal problems or power comsuption increases (the whole machine would slow down at 525/525 and at 500/500 the heat was still a problem) I have decided to leave my GPU at stock.

One new thing, is there a way to softmod my MT-40 to an MT-44? (the 40 is 2.2 Ghz, and the 44 is 2.4 Ghz) Considering it's a small increase and the cach size is identical.
 
If I were you I wouldnt overclock a laptop period. The fact that more heat makes your lap hotter and the faster that things go the faster your batteries dies would be more than enough reason for me to keep mine at stock. Also, in laptops, unlike desktops, you can change the cooling devices, and as such, the performance gain that you could achieve from overclocking a laptop would not be worth it because you wouldnt get terribly far before the heat was beyond normal or even exceptable.
