Servus,
is after a failed overclocking with the stock cooler in the approach I have now mounted the S1 today by Artic-Cooling ... and lo and behold ... ~ 55 ° C at 100% GPU load on the graphics card.
Yay ... since there is now very sensible cooling works apparently also the overclocking ... first try you can see here ... 1700MHz shader clock and 750MHz memory clock, the values are ever to examine the stability now.
To GPU properly you can cause stress, of course, NEN Benchmark start but much more meaningful I think Scientific Software. In my case I take this GPU Grid or PS3Grid which is to be used by BOINC.
