Hi mt_bird,

can you post your complete cgminer settings please?

I am not very familiar with under/overclocking and these settings.

Thanks!

Wow thanks, I set temp to 80 and almost needed to check if the cards are still running, because they are so quite now Grin

Can you give me a hint regarding the Core Voltage too maybe, or can I get more than these 540 and still keep the cards silent (silent != vacuum cleaner)?

You can reduce fan noise by increasing target temp: --temp-target 80, for example. No need to run the card at 70C. 80-85C is still perfectly safe and the fan will be quieter and last longer.

Well, my cards run stable with --gpu-vddc 1.125 at 1100 MHz core clock. You may need to experiment a bit to find the lowest voltage for stable operation at your desired clock.

Hi,
The following settings work for my Sapphire 7950. I am using Linux, though, so there could be differences if you are on Windows. I need to use powertune 20 or else my card's clock won't stay at 1100, but you might not need it:

--temp-target 80 --temp-overheat 87 --temp-cutoff 91 --gpu-engine 1100 --gpu-vddc 1.125 --gpu-memclock 950 -I 7 --auto-fan --gpu-powertune 20
