Default GeForce GTX275 overclocking at Ubuntu 10.04

Hi Everybody!

First of all... Happy New Year!!! :-)

I'm trying to overclock nVidia GTX275 but it refuses to change the 2D or 3D GPU clock frequencies using nvidia-settings and nvlock. I have used commands like:

sudo nvidia-settings --assign="[gpu:0]/GPU3DClockFreqs=640,1133"

and verified results using:

sudo nvidia-settings -q [gpu:0]/GPU3DClockFreqs

and had success to overclock nVidia 9600 GT but it does not change 2D/3Dfrequencies in GTX275.

I have also tried /usr/bin/nvclock_gtk but I just could change the Fan-Duty Cycle of GTX275.

So, my question is: Is that an unsolvable card problem or I'm doing something wrong?

I have tried to find a similar thread at the forum but I couldn't see anything related.

Thanks in advance.

Try adding this in the Device section of your xorg.conf file:

Quote:
Option "Coolbits" "1"
This will add new section in your nvidia settings for OCclocking it, try from there.

Good Luck.

You need to flash the BIOS to your desired settings. These are my 24/7 clocks under water...
