No they didn't 2.1 million chips were photographed ready and in hand by an ex-Bitsyncom member in late June and posted on this forum.
There were never 2.1 million chips photographed at one time, that would be 210 boxes. And it would be something like 700Gh/s, well over the current total network strength, so its not even possible for that many chips to be in use.
Even if they manufactured 1 million chips as they've said, most of them are likely not in use at the moment at all.
Well all I can see there is 26 rows of 10 per tray.
260 chips a tray.
10 trays a small box.
2,600 chips per small box.
3 boxes per large box.
7,800 chips per large box.
I thought someone stated there were 2.1 million in another thread. Also going in facts from anothe thread these would have been made week 24 at TSMC from the alphanumeric script printed in each chip.
