I have installed Ubuntu 12.04 and the latest Nvidia 313.30 driver from their official site on my new System:

  • MSI BigBang XPower II
  • I7 3930K
  • 64 GB 1833Mhz DDR3
  • eVGA GTX Titan superclocked

I've run the Unigine-Heaven benchmark on it and the results were similar to windows: ~20 FPS

Settings:

  • 2560x1440
  • Ultra
  • x8 anti aliasing
  • AO
  • Tesselation factor: 75%
  • Tesselation range: 75%
  • VSync

But then i was wondering about the GPU frequency, in the configuration tool of the nvidia X server the maximum clock speed is 575Mhz, which is, compared to the actual 836MHz base clock, quite low. There's also no fan speed control available.

I was looking for an overclocking tool for nvidia cards under linux and found "NVClock" which i installed using apt-get:

sudo apt-get install nvclock

but unfortunately i couldn't use it because of a bug. When I tried to use it had thrown a segmentation fault error.

And now here i am, I've no control over my Titan at all under Linux, can't manipulate core and memory clock speed, can't change the fan speed.

Do you guys have some ideas that could help solving this problem?

By the way: why is it still running on gen2 PCIe ?!
