I just received two new h-boards, V1.2 as I have a V1 M-board.
Both cards are running at 33-34 Gh/s out of the box.
I measured the R02F resistor and both boards read 2.1KOhm.
My other boards read 1.3KOhm.
Can I still attempt to mod the two new boards?  If so, I don't want to move them much because they are already running high.  But do have very good cooling, 4 fans on 6 cards.
Thoughts?  Input from the wise men?
