Bug Description
This bug has been present for me in all driver versions supporting my GPU in both 12.04 and 12.10, the clock frequencies have been the same. I am using a GeForce660m, which is supposed to have a graphics clock of 835mhz and a memory clock of 4000mhz. The nVidia power-miser settings list only the following options:
0 - 405mzh core, 405mhz memory
1 - 405mhz core, 800mhz memory
2 - 405mhz core, 2000mhz memory
There's at least one other person with my same card having the same issue: http://
I don't know what the power-miser settings are supposed to be, but all three having the same clock speed and memory topping out at half of it's maximum speed seems very wrong.
