Increase max clock range in MSI Afterburner?

The GT 555M in my laptop comes stock at 590mhz GPU / 900mhz Mem. With MSI Afterburner, I can easily max out the sliders to 770 / 1170 which is exactly a 30% overclock on both. It's completely stable and never exceeds 70C. I'm sure there is more headroom in the GPU, but I can't figure out a way to overclock any higher. Is there a way to tweak MSI Afterburner to give me a wider range, or a different tool I could use?

Already there is a huge positive increase in gaming performance. I want to see how high I can take it.
 
tell me what i want to know or i'll mercilessly slaughter an entire family of baby koalas, relishing with glee in their screams of agony.
 
I know of a registry hack that worked for Radeon cards to push 6950 above the Overdrive ceiling after flashing to 6970 shaders and unlocking voltage control, but I'm not aware of such a hack for Nvidia cards. That's not saying one doesn't exist, I just haven't done enough research on the topic.

**edit** Oh, and if you do.... pics please :)

Thanks, I tried that but it didn't make any difference. From what I understand that only works for AMD cards. Are there any tools besides Afterburner for overclocking?
Click to expand...

Sure there are many, rivatuner, evga precision etc.. what exactly are you shooting for as far as an overclock is concerned? Afterburner works on both cards but the unofficial overclocking is indeed for AMD. Sorry about that.
 
Do you really need to overclock that thing any more?... I would be happy with what you've already achieved, and leave it at that. Although you say that it's running stable, this is a laptop we're talking about here.
 
I'm not sure, btu if you get deep into RivaTuner (the software Afterburner is developed from) you may find the answer you're looking for.

guru3D is the place.
You'd have to search the subforum for the answer.

I haven't had an nvidia card for a while, I used to know all those tricks.:eek:
 
You shod leave it as is. Mine ran cool, but icing it brought temps up a bit more (as yours will) and I melted the soldier in the gpu. Reflow worked for a bit. Laptop is now trash.
 
In my experience with afterburner, if you want to change the limits you will have to modify the card's bios and flash it. I had to do this when afterburner wouldn't let me set my fan speed below a certain speed. You could also probably dig into rivatuner. Either option is going to involve some research.
