Thanks for the updates, Dave! We're all anxiously awaiting/anticipating the start of August shipping... Just think, if you deliver by August 30th, you'll be the first ASIC manufacturer with available, substantial hashrate, product to have delivered early, ever.
Another first: ...not to have premined customer hardware before shipping.
Though we *will* test them and pull out bad boards. Even with a 98% yield on the chips, it still means 30% of all boards have a chance of a bad chip
Individual bad chips won't be much of a problem, but if a board has a big group of bad ones or one that doesn't pass SPI down the chain, it will be replaced by a good card before shipping. Our hand-built full rig prototype has only 10 chips not showing up to the party, but there are several others hashing at subpar rates (and the thing is still producing over 400G).
To determine this we will test them for at least long enough to see where the high error rates and/or zero hashing chips are. This is clearly visible within a few hours. As we get more familiar with the boards we can tighten up our test time. This will be a major bottleneck IMHO.
I know some of you will say, "Please don't test mine" and/or "Please send your test hashes to these pool creds", but I just can't support doing that, sorry!
