Hardware error just happen and are a totally normal part of mining. It is not uncommon to see one board with a bunch more than another, it might have a weak component somewhere. Unless you are seeing 10-100x the errors on one board versus the others I really wouldnt worry about it too much. In the end, there is literally nothing you can do to fix it unless maybe you have a firmware that allows you to underclock the boards.
So on my antminer they are called chain #x one has 35 the rest have all zeros. so that's infinity x do I worry?
