Hi there, I am new here and just got into mining in February and love it. I am doing this for fun and really don't care about making a lot of money from coins. I currently am mining on my single Radeon 6870 1gb that I over clocked to coreclock 975 from 900 stock. I only get on avg 210 mhash on it but I have seen people say they get around 300 from a 6870. What could I be doing wrong? I use GUIminer and my card runs. At 65 C under full load so I don't think heat is an issue. Any input would be greatly appreciated! Thanks
