Hi Wolf0!
I don't think so. Using the regular bins I got 2.3 MHs, with yours I get 2.9. Ah, maybe the drivers are somehow screewy. I guess a system format is imminent.
Try it out and let me know. Try 14.7 or 15.7 drivers, NOT latest.
So I uninstalled crimson and installed 15.7. It's actually 0.1 MH/s worse. Ah fuck it. I'll let you know if a complete system reinstall did the trick.
