If you need some help in interpreting the data please contact me. (to directly paste the output to a text file you may type <code>nvidia-settings --query all >> GPUreport.txt</code> Cheers! Thank you for your comment Aikimox,

Even if I put maximum performance instead of adaptive it only goes to power level 1... Would appreciate an advice on this issue. Thanks, Aikimox HI,

Through this nvidia-settings command line you can check the current frequency values: <code>nvidia-settings -q GPUCurrentClockFreqs</code> You can also see the actual settings and much more data with <code>nvidia-settings -q all</code> Thanks for the explanation alfC!

It is difficult to explain, in the PowerMizer tab both clock speeds appears at 100Mhz everytime I have checked. So in that sense it works. However in the Clock Frequencies tab, after I enable Overclocking and moving the slide (in 2D or 3D options) after I click in the Apply button the slide is reset to the default frequency 100 MHz for 2D and 425MHz for 3D. This also happens if I run nvidia-settings with sudo. So, at the end I don't know if it works or not. At least I have been running the laptop for several hours without crashes. (before it never lasted more than 10 minutes). Is it more clear now? Sorry for not being clear. It is difficult to explain, in the PowerMizer tab both

Is it more clear now?

Unfortunately I haven't clearly undestood what you are referring about. You mean that after manually setting the GPU&Memory clock they do not reset after reboot? Instead PowerMizer fuctions always stay at Performance level? alfC, thank you for your feedback!

I had to do all this because my crappy tx2000 shutsdown if the video chip gets too hot. Let's see if it helps.

The Power Savings Settings entry is obtained with this line in xorg.conf (this is described <a href="linux-laptop-power-saving-customization.html" rel="nofollow">also here</a>) <code>Option “OnDemandVBlankInterrupts” “True”</code> basically there is only a checkbox inside enabling you to disable vBlank interrupts, thus reducing by 60 the number of CPU wakeups. For what concerns PowerMizer it should be already enabled with a 'throttling' method. If not you should probably set those strings: <code>Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x3333"</code> Where <code>PerfLevelSrc=0x3333;</code> stands for autosensing dynamic of frequency. You can also add <code>PowerMizerLevel=0x2; PowerMizerDefault=0x2; PowerMizerDefaultAC=0x2</code> where 0x2 means medium performance. Glad to see this post has been of some help for you!
