9300/9400 IGP underclock in RivaTuner?

[finite]

Could anyone with a mATX 9300/9400 board tell me if there is an under clock option for the IGP in RivaTuner? I can make quite a power saving on my regular desktop's 8800GTS by running profiles whilst on 2D so I was wondering if the same thing albeit with smaller gains could be achieved with on board graphics too.

Cheers.

well I managed it in EVGA Precision !!

unclocked the 9400 to try and reduce the 60C idle temp !! - Rivatuner could not tweak the speeds - but could display the current speeds on the monitoring . I think Rivatuner didn't recognise the driver - but EVGA didn't have the same problem

made no difference to the temps of the 9400 !

interesting you had a power saving on the 8800 - I tried downclocking my 8800GTX - and measure the power drawn from the wall - made not 1W of difference

Thanks for the IGP info I save about 9w on 2D idle on my G80 based 8800 GTS 320mb with the clocks (GPU/Mem/Shade) at 260/400/602 compared to the defaults of 513/792/1188.
