@ -355,7 +356,14 @@ There are two "auto" modes in cgminer, --auto-fan and --auto-gpu. These can
be used independently of each other and are complementary. Both auto modes
are designed to safely change settings while trying to maintain a target
temperature. By default this is set to 75 degrees C but can be changed with:
--temp-target
e.g.
--temp-target 80
Sets all cards' target temperature to 80 degrees.
--temp-target 75,85
Sets card 0 target temperature to 75, and card 1 to 85 degrees.

is set to 85 degrees by default and can be changed with:

is not at the highest level set at startup, cgminer will raise the clock speed.
If at any time you manually set an even higher clock speed successfully in
cgminer, it will record this value and use it as its new upper limit (and the
same for low clock speeds and lower limits).
same for low clock speeds and lower limits). If the temperature goes over the
cutoff limit (95 degrees by default), cgminer will completely disable the GPU
from mining and it will not be re-enabled unless manually done so. The cutoff
temperature can be changed with:
--temp-cutoff
e.g.
--temp-cutoff 95,105
Sets card 0 cutoff temperature to 95 and card 1 to 105.

When setting values, it is important to realise that even though the driver
