500 KH/s from R9 270x Radeon card!!
Using a core clock of 1168, TC of 16383, I=18-19, mem 1500 Voltage of 2.225
But there is the trick, I cannot start up at these values, GPU clock must be set to 1120MHz for loading, once I have CGminer going (or in my case CGwatcher running CGminer for me) I go into CGwatcher and edit the cards on the fly squeezing about 20-30kh more from each card. this wont suit everyone, but for me I set CGwatcher to startup with 1120 and set once loaded, if it crashes or whatever it will always go back to mining @1120Mhz and when I notice it has been down I can adjust back to the 1168Mhz and get that little back, how ever my system almost never goes down on these settings so I stay pumping 4x R9 270x @ 500Khs per card and have a shitty dump HD4850 from 10 years ago running my desktop graphics.
