Even $9 a day means you break even in just over 4-6 months maybe longer if difficulty goes mad or bitcoin price goes south. But yes bitcoin mining with a M3 in Africa with your electricity costs means you are on a road to nowhere really. I know you think you did your research but it doesn't sound like it. And certainly doesn't reflect what returns are possible for those who approach the field with more care and due diligence. That being said, as a technical experience and way to get to understand mining and its ins and outs you cabymt go wrong with what you have done, and if you break even (which you should if you don't start spending money on archon) and even make a small profit it will not have cost you your life savings. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Hi all, I received brand new M3 miner. It's been on for few hours, but I can't get anything past 9TH/s from it. It supposed to be 11.5 TH/s, right? That's what I see right now: https://screenshots.firefox.com/NTap216qScJkeNZG/192.168.1.181Auto-frequency is complete and miner is just mining on maximum frequency, but reported hashrate is much lower what is supposed to be. Same on the pool side: "hashrate1m": "7.75T", "hashrate5m": "8.34T", "hashrate1hr": "7.34T", Here's whole cgminer API report: https://pastebin.com/raw/MQft9cuBBoards should have 3700-3800 GH/s per board, but I am having only 2916, 2726, 2828 (GHS5min, just refreshed now). Any thoughts?

Update on my issue from previous post. I've been back and forth with Pangolinminer support, so far that got me nowhere. I verified it must be power issue. When 2 hashboards powered, they are doing rock solid: Elapsed 4 hours 11 minutes GHSav: 7922.22
SM0 GHS15min: 3899.24 SM1 GHS15min: 0.00 SM2 GHS15min: 3981.65 But once I connect third board, whole miner slows down to: Elapsed 6 hours 46 minutes GHSav: 8594.57
SM0 GHS15min: 2862.94 SM1 GHS15min: 2917.81 SM2 GHS15min: 2921.11 I tried to use different power supplies, Bitmain APW3++ and Bitmain APW3, to let them power only 1 hashboard at a time, but each different power supply I tested is working slow with M3 miner. Only original PSU seems to be good enough to power a hashboard (or 2 hashboards) to full hashrate. But I can't get 3 boards powered with anything and have full 3x3900GH/s = 11.7TH/s from that miner. ![Angry](https://bitcointalk.org/Smileys/default/angry.gif) Anyone experienced something similar? Is my PSU flawed? Why is miner not working with other PSU? I requested warranty repair from Pangolinminer, waiting for them to respond.

I've not seen similar issues before, so it is little difficult to give any advices. ![Undecided](https://bitcointalk.org/Smileys/default/undecided.gif) Using the WhatsPower P3 psu, have you connected all ten 6-pin power connectors (one to controller and nine to hash boards), AND also the 3-pin connector from the psu to controller board ?

Yes I did. Everything connected, 10x PCI-E and 3-pin connector to controller board. If I not connect 3-pin connector, what will happen then? Is there any difference in miner hashrate?

It is for communication between control board and the psu.
I recommend keeping it plugged in.

But if my PSU if faulty and can't handle 3 hashboards, I will have to use different PSU, and there will be no communication between them? I wish this is explained a bit more by Pangolinminer. What's the purpose on that communication?

What's the purpose on that communication? The control board is controlling the power supply. I don't know more about it, since no documentation with exact details about that communication is available. I doubt it's any help, but here is the Whatsminer M3 user guide: https://drive.google.com/file/d/1lWv1mYZoHdSurfNGx6DxBIYj34MawzCs/view

Power control cable (three wire) must be connected well, or might cause the error to control the power supply, leading to the low hashrate. But there is no way to verify if mine is connected and working or not. What if it's faulty? No way to find out why I have low hashrate. And manufacturer is not selling PSU separately, so if your PSU dies, you can't have original one, you will have to use different PSU. And different PSUs are showing low hashrate, frequency is not even reaching 600 with them.

These “excellent prices” only reappeared after bitcoin tanked. And guess what they only accept bitcoin. No thanks, not giving them $2400 worth of btc just because it is is worth $1200 at this minute.

Thanks, no problem. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I fixed a typo, there was a wrong caption text under 'Cgminer configuration page' image. It now says 'Cgminer configuration page' as it should say.

I have fixed the opening post. The manufacturer is actually WhatsMiner company and their official overseas distributor is Team Pangolinminer. I had misunderstood this company arrangement. About Team Pangolinminer Team Pangolinminer is founded in year 2016. Locate in Shenzhen,China.And now serving below sector of Blockchain industry.
Crypto Currency Miner Pangolinminer start business in blockchain as Miner in early 2016. Till now, we have our miner portfolio including Whatsminer (BTC) and Pangolinminer (ETH).
Miner Distributor Team Pangolinminer has made a joint venture with Whatsminer Company in year 2017. In this case, we has became the official overseas distributor of Whatsminer series. Until now, we have already sold 20,000 whatsminer M1 and M3 around the world.
