    Those are the only ones I happened to have access to. I never heard that GTX400 cards and newer can't overclock, but I suppose I don't have a reason to doubt that. Honestly though, aside from testing for stability, OS GPU overclocking tools aren't really the best way to go because they're always temporary. I personally replace the GPU BIOS, so I don't have to worry about an OS not supporting the higher clock speeds known to work.

      Yeah, Michael has mentioned in previous articles that the Fermi and Kepler series of cards don't support overclocking when using the Nvidia binary drivers.

        Do they work in Windows?

          I'm pretty close to getting "Optimus" working. Unfortunately, my Nvidia card isn't wired to HDMI or any output and the LVDS doesn't want to play nice.

          I'm getting a blank, backlit screen. X will start without complaining, run programs invisibly and glxinfo will report Nvidia, but there's nothing on the LVDS or HDMI.

          Unity and other DEs will try to load, but report framebuffer errors.

          Providers for Nvidia and modesetting (or Intel, I've tested both) report properly.

            XP/Vista users don't get that feature either (because the OS lacks support), so I'm not sure why linux users felt they were entitled to the functionality in the first place. nVidia tried to offer some kernel patches to enable Optimus in the past, but these were not accepted. Now they are using an alternative approach using a feature in RandR 1.4 (which wasn't available at the time Optimus was introduced).
            Kinda sorta right. XP Doesnt support optimus at all. Vista CAN support it but it requires a BIOS flag. This issue came up at linux.conf.au (I forget which speaker... was David, Daniel or Keith) Vista had to have a hardware (read: BIOS) flag to switch between the GPUs, OS X mandates a hardware flag just to make sure it works properly, Win7 doesnt require a hardware flag. Became an issue of "Well OS X does it this way... Windows does it the opposite way... which do we do?"

              Nvidia's kernel patches and dma-buf suggestions were implemented in a way that satisfied 90% of what they wanted. It's the main reason why this requires the unreleased 3.9 kernel.

              They couldn't use randr 1.4 without it.

                For me this driver is not realy good.
                With this driver i have a lot of spam like

                  Do the crazy logging activities affect normal performance with the driver?

                    Since those messages blowing up the logfiles, after a while the desktop does not response anymore.
                    So i can't say anything about the performance, i have switched back to 313.30 driver.

                        I'm getting a blank, backlit screen. X will start without complaining, run programs invisibly and glxinfo will report Nvidia, but there's nothing on the LVDS or HDMI.


                        Providers for Nvidia and modesetting (or Intel, I've tested both) report properly.
                        Same here. If you make any progress, it would be great if you could send me a PM to point me in the right direction. Btw, I wonder if this error in Xorg.0.log
                        could be related:

                          Are you configured your X as suggested in readme:
                          http://us.download.nvidia.com/XFree8...E/randr14.html

                          You will need a xorg modesetting driver for kms(in ubuntu it's named xserver-xorg-video-modesetting).

                            It works - but with some tearing

                            Hi,
                            I managed to get the NVidia GPU to render throught the Intel GPU to a Laptop Screen as well as over HDMI to and external monitor.

                            Process detailed at http://www.barunisystems.com/index.p...page?view=blog
                            Regards,
                            Chaitanya

                              Yep. If you mean the xorg.conf file. If you mean the kernel CONFIG_DRM parameters -admit beyond my knowledge- : I don't know. Using Ubuntu Mainline 3.9 rc6. Could this be the point?

                              Thought Intel >2.21.5 should work also? I started with modesetting driver, same.

                                Is the tearing issue fixable by Nvidia or Intel via driver changes or is this something that the technology just has to live with?
