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?

Yes, you can pencil mod them and they respond as well as the previous boards, do not go as low tough. I've found that any board can take 1.72 and ones with very good cooling (3 fans per bank and heatsinks) can go as low as 1.63KOhm. I'd try to lower the resistance by 0.05KOhm at a step and see how the cards respond.

Makes sense. Thanks guys.
