MCLK defaults high on second card

Hi,

I have a setup with a CZ + Polaris10 and on the Polaris10 the SCLK idles 
low and the MCLK stays in the 2nd state (1750MHz) but on my Workstation 
which has a single 560 in it the card idles at 300MHz (with the stock 
FC27 kernel).

Is there an issue with non-primary cards idling properly?

Doing

echo 0 > /sys/devices/pci0000:00/0000:00:03.1/0000:21:00.0/pp_dpm_mclk

Doesn't result in low clock rates either.

Tom
