The N75 has a very nice overclockable GT555M onboard. I can get a stable overclock with the GPU at 780 and MEM at 1000. But we always reach for more as overclockers. The standard clock is pretty high anyway 675/900, so that could explain the higher voltage. I do not know the standard cpu / mem speed in the N55.

That's a damn shame, I would have tought it could be done seeing the N55 has a mod.

Well, thank you very much for looking into this!

There are several entries in the voltage table, don't know whether they'll work though... can you quickly tell me what GPU-Z reports (voltage) when running at 3d clocks?

GPU-Z reports 0.9250 when running at 3D clocks.

Let me take a look at it. I'm not at home at the moment, so I might not have all the necessary tools here, but I see what I can do. In the worst case you'll have to wait about 1-2 weeks until I can check it out, in the best case I have a test version ready in the next couple of hours.

Edit: N75SF or N75SL?

Edit 2: There doesn't seem to be a BIOS available at the Asus site for the N75SL, so in case you have the SL you have to dump me your BIOS, I'm not sure whether there are some differences...

It's the SF, you can download the BIOS from here ASUSTeK Computer Inc. - Notebooks- ASUS N75SF. Take all the time time you need, I'm allready glad you will look into this

Are there any plans to do a volt mod on the N75 Bios? If so, I am able to test it.
