Many of us buy only from the mfrs direct, or from endorsed, official distributors

Would BITMAIN pre-sell one version and then ship a different one?
This is what Eastshore is claiming why they have the different version to ship in the first place.

FWIW, the 2 S9's I ordered for Dec 11-20th batch show Antminer S9-14TH/s in the order status. Granted that doesn't mean anything since I think they claim +/- 5%. This is my first Bitmain order.

I ordered 4 S9 14TH from Bitmain. All of them had the nomenclature showing 14th/s however one has never, ever, ever hashed above 13.7TH/s. The other 3 are within specs. Of note, the configuration in the one that does not hash to the advertised TH/s is the hottest running machine and the Freq for each hashing board are lower than the 14th/s ones. Hope this helps.

My S9 from late november batch is labeled as 13.5 but it always mining around 14.0 Th .

The autotune freq colum 'ídeal' shows it tries to get 13.5 Th but it does not succeed and get constant average value of 14.0 Th , same every reboot.

Downside of this extra TH is that the antminer takes 1500 watt instead of my older S9 that only consumes 1400 watt. I would like to underclock a little.
