I've confirmed with BITMAINTECh that its not possible to identify that an Antminer S3 is different from other from physical review, i've ordered 2 from amazon from some guy who's not BITMAINTECH, i'll be posting about my experience, perhaps i could check which firmware the antminer have and verify that i have Batch 7 (since thats the one "pre-ordered"), any ideas are welcome boys.
what exactly are you trying to do???
I bought 2 antminer S3 that are supposed to be Batch 7 from Amazon from seller: Bitmainantminer <- thats his name on amazon.
They will arrive soon, and i need to verify and certify my self that those units are:
100% working parts & real parts
Never used
Batch 7
So, my only idea since there's no way to verify that the batch is actually BS7, is to set frequencies and see what # GH/S i get.
Why didnt you just buy from bitmain instead of a marked up (and probably used) unit from amazon?
