From what we know burnin receives nothing at all from Avalon directly.

There are a few public group buys, and of those only zefir has received and forwarded his first batch to burnin. The other batches haven’t even shipped yet.

Of course there is always the possibility that somebody ordered a whole batch of 10k chips for himself, received them and shipped them to burnin for a "private run".

(correct me if I got something wrong)
