Firstly, thanks to Claymore for the improvements here! On most of my rx 470 4GB cards, I am seeing about a 3-4% increase in hash-rate!

However, I was hoping v11 would also alleviate an issue I've been seeing since starting to use v10.2 a while ago.  For some reason, GPU 0 on all 4 of my rigs acts very strangely... most of the time hashing well below the others... fluctuating between 0 and 450, while the other 5 are right at the 700 mark.  Now, if this were only on 1 rig I would think the GPU is going bad, but since it is the exact same GPU slot 0 on all 4 rigs, it is more likely some kind of setting that i need to tweak.

Has anyone else noticed this on their rigs?  If so, any suggestions on how to fix it?

FYI: after just upgrading all 4 rigs to v11.0, GPUs 1-5 are hashing better by about 3-4% but GPU 0 is still bad on all 4. Although, it doesn't seem to be fluctuating as much... pretty much stuck at 232 on 3 rigs and weirdly, 120 on the 4th.

Any help resolving this would be much appreciated!
