Topic: gpu UNDERCLOCK

I know there is alot of talk about overclocking the NVIDIA gpu, but what about underclocking? I want to save battery but without the reboot tongue .  I am toying with nTune, and it begs the question: How low can I go while still being able to do basic things such as using Word or web browsing?
Thanks

Re: gpu UNDERCLOCK

And you should learn to read  tongue

He clearly stated that he wants to save battery WITHOUT rebooting, which you have to do to use the Intel GMA.

On-topic: I haven't tried underclocking it before, I'll see if I find some time to try it. I'm curious to know too  wink

Don't make me "touch" you :-D

Re: gpu UNDERCLOCK

forget about it.
But I heard some people managed to change gfx card using "waiting mode" - I don't know how It sounds.

The card has 3 clocks: 2D, 3D Low Power and 3D Performance.
During normal use, like web browsing and office applications, the 2D clocks are used, which are: (Core/Memory/Shader)
275/250/550
which are pretty low compared to 3D Performance, which has the clocks:
580/400/1450.

However, if you think to underclock it even more, these are the clocks CPU-Z tells me when my card "fails" (by fails, I mean the computer has faced "something" that the computer needs to be rebooted for the GPU to use the 3D Performance clocks):
169/100/338.

But keep in mind that even the RAM starts to fail when DRAM freq goes down to 133 Mhz, so these might be the minimum clocks.
