Right now this is my configuration:

- ASrock Extreme 4 970
- AMD Phenom II X2 555 Black Edition Callisto 3.2GHz Socket AM3
- 4GB Ram Kingston
- Toshiba Sata3 1TB
- 11221-07-20G (Sapphire R9 280X OC Dual-X 3GB GDDR5)
- PSU Nox Urano TX 1050W
- Windows 8 fresh installed for this.
- Catalyst 13.12 (last version)

Right now im getting exactly 700khash. I want to know if it is possible to run it over it. I have all in a place with an stable temperature of about 10ºC to 15ºC.
Actual configuration to run cgminer from cgwatcher is: -I 13 -g 2 -w 256 --lookup-gap 2 --thread-concurrency 11200 --gpu-engine 1020 --gpu-memclock 1500 --temp-target 80

I want to know if it is possible to go over 700khash, at about from 730 to 760.

Thank you.
