I have to disagree. My cards are stable up to 1230 and 2225 and beyond on 11.0.  It seems like any version above that even 1180/2135 I get 4% incorrect and no amount of underclocking  gets rid of them.  Anything faster causes instability.  For me the faster speeds on 11.0 is a much better deal.  I can go a lot faster than 1230/2225 on 11.0 as well.


But I do have timing straps done on rx580 micron ram. I have a feeling that is the issue much more than OC speeds.  Especially since the Nvidia guys don't seem to have any problems.
