92C is really too high to mantain the 24/24h mining.
The aticonfig command is the ati command to check/change the settings of the videocard. Check your speed clock with
aticonfig --adapter=all --odgc
and try to downclock it if is overclocked with a new cpuspeed and memspeed
aticonfig --adapter=[number of your card 0 or 1] --setclock=cpuspeed,memspeed
you can set memory to 300-400MHz max
E.
These are the results:
btc@test:~$ aticonfig --adapter=all --odgc
Adapter 0 - AMD Radeon HD 6900 Series
Core (MHz) Memory (MHz)
Current Clocks : 880 1375
Current Peak : 880 1375
Configurable Peak Range : [500-950] [1375-1450]
GPU load : 99%
btc@test:~$
btc@test:~$ aticonfig --adapter=0 --setclock=800,400
aticonfig: unrecognized option '--setclock=800,400'
aticonfig: parsing the command-line failed.
btc@test:~$
set clock doesn't seem to work. But From the --odgc it looks like it's clocked to max?
