Anyone opened up the miner to look at the boards? I'm curious if there are markings on the weak hashing boards to indicate some sort of difference and that bitmain knew something about them. Seems very coincidental that so many of these batch 2 miners have 1 weak board.
So because you cant OVERCLOCK one board as much as the others you are jumping right to a conspiracy theory that bitmain is doing things on purpose?
The boards are not weak, they hash just fine at the factory speeds.
There is NO guarantee of overclockability, you should be thanking bitmain for putting out a unit that can overclock by 40-60% in the first place. They only promised 10k sols out of the device....
I agree that technically they were honest with them providing their product to the advertised spec. But you can't say it isn't shady or misleading to give first batch users some extra unexpected hashing power as a silent marketing strategy just to sell batch 2s to folks expecting the same. I'm not going to bitch & complain about it because yes, I'm getting no less hashing power than what I paid for, but also I personally do not support this marketing practice and as a result I will never be purchasing another Bitmain product or recommend them.
Edit: Also, this is neither a conspiracy nor a coincidence. It's simply silicon binning which is a standard practice throughout the entire semiconducter industry because all chips from a batch are not created equally. The part where it gets shady is that it's likely the highest quality chips were reserved for the batch 1s so everyone could hype over a 50% OC and then pre-order batch 2s.
