Gentlemen if you are having issues with claymore 11.x that you didn't have with 10.x but it want to mine keccak or verge do this.  Upgrade to 11.5 which was just released.  You need to add "-oldkernels 1".  You will have your stability back with no incorrect shares and a small speed bump too!

I have one micron card doing 32.2 and 245 keccak.  1215/2200 at 900mv
