How to downclock my mobile chipset?
 
Environment:
  • Hardware GeForce Go 6100
  • OS FreeBSD 7.1-PRERELEASE
  • X xorg-7.3_2 ('Coolbits' option is set to 1)
  • Driver nvidia-driver-180.16
Code:

$ nvidia-settings -q GPUOverclockingState -q GPU2DClockFreqs -q GPUDefault2DClockFreqs -q GPU3DClockFreqs -q GPUDefault3DClockFreqs -t
1
100,0
100,0
425,0
425,0

Tried to downclock without success - original clock value did not change:
Code:

$ for ((i=99;i>=25;i--)); do echo "--> $i"; nvidia-settings -a GPU2DClockFreqs=$i,0 ; nvidia-settings -q GPU2DClockFreqs -t ; done
--> 99

  Attribute 'GPU2DClockFreqs' (tut.at.home:0.0) assigned value 99,0.

100,0
--> 98

  Attribute 'GPU2DClockFreqs' (tut.at.home:0.0) assigned value 98,0.

100,0
...
--> 26

  Attribute 'GPU2DClockFreqs' (tut.at.home:0.0) assigned value 26,0.

100,0
--> 25

  Attribute 'GPU2DClockFreqs' (tut.at.home:0.0) assigned value 25,0.

100,0

Code:

$ for ((i=424;i>=106;i--)); do echo "--> $i"; nvidia-settings -a GPU3DClockFreqs=$i,0 ; nvidia-settings -q GPU3DClockFreqs -t ; done
--> 424

  Attribute 'GPU3DClockFreqs' (tut.at.home:0.0) assigned value 424,0.

425,0
--> 423

  Attribute 'GPU3DClockFreqs' (tut.at.home:0.0) assigned value 423,0.

425,0
...
--> 107

  Attribute 'GPU3DClockFreqs' (tut.at.home:0.0) assigned value 107,0.

425,0
--> 106

  Attribute 'GPU3DClockFreqs' (tut.at.home:0.0) assigned value 106,0.

425,0

Any suggestions?
