Are you talking about incorrect share or rejected share?
OP thinks re-loading Claymore will fix OP's problem (
as shown on the OP's first post) but then OP giving us (
3rd post) error message that appears on OP's Claymore:
"GPU #3 got incorrect share. If you see this warning often, make sure you did not overclock it too much!"
So, what was OP talking about is incorrect share.
