Is it a new firmware form Batch-3? Has anyone tried it? What is about overclocking?

it's a new firmware and does not allow OC.

I noticed the control board has a connection for 1 more hash board is it possible to connect a 4th board to the miner? Has anyone tried if it works or dose it need a custom firmware to initialize the 4th board? I was thinking about building its own case for it with 4 boards instead of 3. I read on another thread that some one fried one of their boards and ordered a new hash board for 200 bucks form bitmain. Thoughts?

almost every antminer (even older models) has one additional connection. I thought the same but no one did it before. I doubt that bitmain will send you a new board (solo) for 200 usd.
