Best ROM for RX 480 Reference

I've been testing with my 6 RX 480s on Windows 7 and can't seem to get over 145 Sol/s. I made more changes this morning right before leaving for work and of course it hung... so got nothing right now... figures, haha! I was wondering what ROMs people are using for the RX 480 Reference 8GB cards and what kind of speeds you are getting. Thanks!

EDIT: Also what driver version. :slight_smile:

Claymore V7.0 should get you 160 easy
