Hello there,
download MSI afterburner, and overclock it a little bit. Change Core Clock to 899 MHz and Mem clock to 1798MHz and use this configuration:
cudaminer.exe -i 0 -H 1 -C 2 -l F16x16,F16x16 -o stratum+tcp://yourminingpool.com:3334 -O user:pass (temperature shuould be around 78ºC with fan speed at 60%)
With this configuration I am getting ~300KH/s.
Thank you for the info but I can not overclock the core clock any more then I do the heat and stability just do not work out and I end up with blue screens or the hashing drops way low. As far as memory clock goes, they are stock 2004mhz I guess I could try under clocking them but would that help? I use Precision X to adjust but it will not let them go below the minimum of 2004mhz. Does afterburner allow this?
