(ethminer) ASUS 7970 Directcu II Top only 501 MHz @95 C @Fan 100%

I'm running

Ubuntu 15.10
AMD drivers radeon-crimson-15.12-15.302-151217a-297685e
Genoil's ethminer

but I only get 10 MH/s because the GPU clocks only at core 501 MHz (normal 1000) and memory 1400 MHz (normal 1400) and sensors say 95 C / fan 100% (3500 rpm).

I've read there was a bug in 2012 if you run also a youtube video but everything is off except ethminer.

If I change the settings like this

Code:

aticonfig --initial
aticonfig --od-enable
aticonfig --adapter=0 --od-setclocks=1050,1450

the gpu core clocks still at 501 (not changed) and the memory now at 1450 (changed).

If I change the settings like this

Code:

aticonfig --adapter=0 --od-setclocks=400,1250

the gpu core clocks now at 400 (changed) and the memory now at 1250 (changed).

Thanks for every hint!

P.S. Are there any active links to download a Stilt BIOS for the 7970 and 7950?
