    So all through June there was always a newer, faster x11 miner release every few days it seemed, and I'm starting to wonder if I'm still using the best software available since I haven't updated anything for over a month now. I am currently using sgminer_14.6 and have dumped the ocl files from the 14.6 drivers in the sgminer folder before compiling bins. Source: https://bitcointalk.org/index.php?topic=658411.msg7437349#msg7437349. My 270s are currently putting out 2.72mh each, 7790s 1.74mh each, and 7950s 3.82mh each. I have done some searching and testing but even the nightly builds on nicehash just don't seem to get nearly the same hashrate (I could be configuring them incorrectly thou). If anyone knows of some better software please share. Happy mining folks!

    Here are the important bits...
    "intensity" : "17",
    "lookup-gap" : "2,2",
    “gpu-engine” : “1130,1130″,
    “gpu-memclock” : “1500,1500″,
    “gpu-powertune” : “10″,
    “thread-concurrency” : “22400″,
    “gpu-threads” : “2″,
    “worksize" : "256",
    Etc.....
    They are Sapphire 3L units, stock bios and stock voltage (1.25), each pulling ~200-210w. Hope this helps, and let me know if you manage to squeeze any more from them.

    I recall someone in the ANN thread on bitcointalk mentioning undervolting their cards actually increased hashrate, anyone have more info on that?

    My 280x is undervolted @1.070 mv (at default it is @1.200 mv) and I get 4.1/4.2 mhash/s with underclocked memory clocks
