One of my batch 1 units will not overclock. In fact, sometimes it won't start up at all.

I have it taken apart right now. I am running to the store to get some alcohol for cleaning (well, maybe some other kind to drink as well...).

Several of the chips have this problem.

I know that some people say that thermal paste does not conduct electricity. However, the thermal paste that is used by BitMain has some oil in it which I do believe conducts some electricity (as learned from my S1 experiences). I am hoping a cleanup job will fix this S3.
