Question for Radeon HD6770 - How much Power can I get?

[Georg2013]

Hello,

recently started to mine with cgminer on a system with,

AMD Athlon II X2 250 3Ghz ; 4 GB DDR3
ATI Radeon HD 6770 1GB GDDR5

Now my question, with Intensity 12 I reach barely 130 KH/s on Scrypt. could push it to 180 with I:15 but then the system goes a bit laggy but still operable. GPU Temp around 60°C

Now I tried to raise Engine Clock from 850 MHz to 950 MHz and got 200 kH/s temp raised to 62°C.
I didnt try to Change RAM Clock: which is at 1200 MHz at the moment and Voltage at 1.2 V

Dont know if it would be any improvement and if my Card could get damaged, or if the 200 KH/s are already at its limit

thx

200kh/s is maximum you can get from that gpu.
Not worth of mining, specially if you don't have free electricity.
