Gateway P7811-fx gpu voltage!

post #1 of 8
Thread Starter 
Hi Guys,
Am using gateway p7811-fx and you know the oldest problem with it the "black screen of death" so i think it might be because of gpu voltage cause when i use it.It reaches 1.11v and i think its pretty high for laptop i used riva tuner but it really dropped my fps so i wanna know how to change voltage of gpu i tried softwares like msi afterburner,evga precision but they didnt worked for me as they dont even show the voltage bar even when its unlocked in settings.
So please guys help me.

Um, did you do anything to the laptop before?

When does the black screen occur?


EDIT: Typically mobile GPUs' voltage are locked. In fact, my Radeon Mobility 5730's voltage goes to 1.1V when I set it to High Performance mode, and back down to 0.95V when in the Power Saving mode.

1.11v isn't really that high for laptop GPUs. My 6970M would normally run at 1.1v under full load.

You can only undervolt it if it's allowed via bios flashing it. The black screen of death sounds more like a dying GPU, which shouldn't be surprising since the GPUs that those laptops employ are VERY aged by today's standards. I'm kinda surprised that it's still running. blinksmiley.gif

You can't change the voltage on a laptop GPU with software. It's set at whatever it's set by the manufacturer. I would try updating the BIOS on the card. Otherwise, you may just have a heat issue that could be solved by cleaning out the vents and replacing the thermal paste on the GPU.

Also, you can't really get upset with the OCN community for not helping you out on this matter. This site is 99% dedicated to desktops, for obvious reasons. Most people don't overclock laptops tongue.gif You'd probably be better off on notebookreview for this kind of question.

Yes you can? I'm not sure where you heard that you can't change the voltage, but odds are probably with the user that they can. I undervolted my GPU to ensure it doesn't draw as much power or generate as much heat... tongue.gif
