Being engineers, they more than likely they ordered 30% more of everything than they needed, and they already planned for the 2nd batch orders. I would guesstimate, they have plenty of on hand and are willing to toss some components if necessary. Figure a 5% failure rate at worst for these scenarios, so it's within acceptable boundaries.
Yeah. I think they still have margins on margins. We know there are 4 engines in the chip. I think they might be quoting us a 100 gh/sec figure based on three of those engines working when we might very find all four working.
So, perhaps the theoretical max hasrate if all four engines are working is more than 125 gh/s per chip, but more like 150+, perhaps even 166 or so. Putting our hashing max at some 650 gh/s. We shall see.
