<pre>The windows driver should operate pretty much the same as the linux driver as
far as I know. I'm not really familiar with how gpu-z reads back the clocks
and voltages and that may have something to do with the differences. Not all
of the aspects of the level transition happen at the same time.
You could try setting the vddc to 1060 and changing the mclk of level 1 (mid
level) to 650Mhz. Perhaps the jump from 150 to 1300 is too big and the pll is
not able to lock properly.</pre>
