Is it the missing DPOT?
I located the PIC which is PIC16F1704 by Microchip in these pictures of the hash board,
but I could not find a DPOT.

I guess not. Phil didn't get a green light for his paypal proposal yet and btc payment has been a no go.
I simply can not understand why Canaan is this way stabbing their own knee.

Bitmain will most likely continue working with TSMC, so I guess a 10nm chip is to be expected from them next.

This not a proper business proposal, I say this is begging.

They basicly are 3x COM pins.
The sense in the GPU is grounded and when that circuit so closes, the GPU knows that I got a cable.

You are right though that if we are totally official we should call it sense.

The lack of BTC payment could have fatal consequences for A721 sales.
I think that they have not thought this through.

Yes one of the grounds is for the GPU's Sense connector to tell that "hey I'am a connected cable".
And as I said in most cases there is 3x +12V pins.

Official standard though indeed declares that one pin as an empty connection.
I haven't personally seen this in any PSUs but it is possible to find this situation.

My picture is for most cases, it is not the standard.

Here is a link for the pinout according to the standard for those who are interested: http://cdn.overclock.net/a/ac/ac82eb1d_pinout.png

Yeah, the official standard declares one plus pin as "no connection", but most PSUs provide +12 volts at this pin.
So in most cases there is 3x +12V and 3x COM pins.

This is the case for most PSUs:


The official standard declares the pin number 2 as a "no connection".

Yes, it shows two devices A711-S-0-1 and A711-S-0-2.

That's pretty nice 0.22J /Ghs efficiency

He's talking about me.
I just received a second S9 11.85Th/s model from Eastshore.
Great condition and I have overclocked it to the max. it can do, 13.2Th/s.
The first S9 11.85Th/s which I bought from them is running at 14.1Th/s.

They are performing better than the S9 12.93Th/s model that I bought straight from Bitmain  
The 12.93 model is actually underclocked right now and mining with Enermax Revolution 87+ 1000W PSU.

I have a total of 3x Antminer S9.

It is a sad thing though that Eastshore only has the 13Th/s autotune frequency model of S9 for sale right now. 
I personally don't like them because they are less controllable.

You are right, I'm from Finland and I'm using at the moment nl.kano.is (Kano.is pool) as a primary pool, de.kano.is (Kano.is pool) as a secondary pool and then the third pool is a solo mining pool de.ckpool.org (Solo.ckpool.org pool).
This is a one good choice for EU guys.

Also Kano has few different nodes, so you can put them as backup if you want
USA: stratum+tcp://stratum.kano.is:3333
Netherlands: stratum+tcp://nl.kano.is:3333
Germany: stratum+tcp://de.kano.is:3333
Singapore: stratum+tcp://sg.kano.is:3333
Japan: stratum+tcp://jp.kano.is:3333

The lack of BTC payment and the power efficiency compared to the S9 made me say bye bye to this  
This is sad because I had great time with the A6.

I kind of supported you and bought one of these GekkoScience PSU kits in bitshopper.de that you told me about 
https://www.bitshopper.de/shop/zubehoer/hp-dps-1200fb-psu/

This is good for guys in EU area.

Exactly.

Would you sell me one for 1500USD including shipping to Finland?

I have the account at canaan.io and I could not find a page to buy one.

Yeah it worked now and I was able to look into this.
I contacted Hotmine and I try to create an order for 1x "X6 Miner", let's see what they say.
I would be happy to have a reliable European miner and support an European business.
