If you're not already using them, there are the Kachur ones.
Just download the latest nice hash miner and check the bin folder.
Which bin folder of the three (5.1.0, 5.1.1, or 5.2.1)?
5.1.0 works best
Wow thanks so much for the tip!! Mining X11 at 26MHs now, compared to 15MHs before!! Power use went from 450w to 530w for the system. You got a donate address I can send some BTC to?
