Hi guys....real noob here...so bear with me...I've read through all 30 something pages of the forum, and I'm thinking about ordering a few 741's, but just to clarify, for each unit, I have to purchase a PSU for it, and am I right in thinking that will add another few hundred dollars cost for each unit? I see the price has gone up to 798 each now, so probably looking at around $1100 total per unit W/the PSU? Appreciate any feedback...thanks.

do you have 120 volt or 240 volt power?

if you can provide 220-240 volt power the gear from sidehack is really good.

well under 100 bucks

se the avalon to -1 for a slight power/noise/hashrate drop and sidehack's kit will work great.

I ordered another 741 should come soon.

If you have 110/120 volt the psu will work but you would need to set the avalon to -2

Ahhh...thanks...I forgot to mention my location...so I'm in the US...so have to be 120V....so the only option would be to set the hardware to -2?

Thanks

I doubt the A7 would work on DPS-1200 @ 110V even at Voff = -2. Another tip is dont try to top up your PSU spec output. it's always a prudent practice to leave some "room" for it to breath.

Yeah, good point, I forgot this as a Finnish guy.

With 120V voltage the HP DPS-1200 is only able to provide 900W power which is not enough for the Avalonminer.

80$ and you can get a rock solid PSU from sidehack

I have a question, I finally set up my 741 using Kano pool setting.
It has been roughly 24 hours and I have received 2 deposits one for 0.000129 BTC, very surprise they deposit so small.
and just checked recently and saw another one coming for 0.00045468.
I really thought the miner would do better than that or do I have a setting that is off?

This is what my miner looks like:

Read thru https://kano.is/index.php?k=payout

Don't worry, Canaan is much more reliable than BITMAIN. Have you opened up a ticket? I discovered that communication is most consistent when communicating through their ticketing system.

Stupid question, sorry.

How do I power it down if I want to move the miner to another room?

Thanks and sorry for the stupid question, could not find the answer anywhere.

Go to CGminer config panel, and just type "poweroff" to More options, and it should stop mining, from this point you can wait a little to make it cool down and just shut down the PSU, and here you go

Awesome, Thank you!

I am thhinking, is it really more in advantage to mine bitcoins thhan to just buy them in exchanges? Can we mine Bitcoin Cash with this miner?

No. People are buying these just for the fun of spending their hard-earned money... Tongue

Depending on your setup and cost of electricity yes it CAN be better than day-trading BTC on exchanges! I do very well with my farm. Also, as said by others BCC is NOT Bitcoin. It is a fork from it and should be discussed in the altcoin area.

It all depends on the cost of electricity. For me, it is less expensive to mine bitcoin than it is to purchase an equivalent amount of bitcoin directly from an exchange. Since BCC is an altcoin, I would probably discuss that in the altcoin section, however i would assume that this miner would be compatible.

Only 3 cons:
1.All miners on 1 controller show up in the pools and monitor sw like Awesome Miner as 1 big device
2.Single point of failure if RasPi dies
3.When updating the MM firmware it is applied to ALL miners on the controller. NP if they all are the same model, not good if you mix say 721 and 741 miners on the 1 controller. Been there - done that and 721's don't like thinking they became 741's....

1. So, I guess from a management perspective if one miner in the chain goes down you've gotta dig into figuring out which miner is having the issue. Is that the main con?
2. Valid point, I don't really have any experience with raspi, are they generally reliable or are they more prone to failure?
3. I will have 741's only, so not an immediate issue, but good to know.

Ya. The only way to easily see the status of each miner is to use the Avalon GUI. It will ID the AUC adapters and the miners attached to them, tell you how fast each is running, etc. There you can make a miner's LED blink so you can pinpoint which is which.

Can't say I've ever had a RasPi fail but is still the Achilles heal to what can be a very large amount of hash power. Then again, easy enough to have a spare Pi already configured as you want to just plug in.

My biggest issue would be that because all the miners are reported to pools as 1 worker if there are say 10 miners on the 1 controller and 1 miner drops out or loses speed it will not be apparent for a while if you only look at the pool stats for that (huge) worker.

Thats a good point. I am also trying to think ahead about scalability issues. If i theoretically were to buy 20 of the miners and send them off to hosting, or build out my own version of a gigapod i am not sure the best way to set that up. Buy a controller for each unit? I think while i have the equipment here, locally, 4 per controller would be pretty simple.

if buy solar and I end up with say 18 741's we would use 6 rasp pi's 3x 741's per rasp pi .

this gives you spare usb to 4 pin translation dongles

along with finksy 4 k psu's 3 pieces per rasp pi is a working plan for our future build out ( if we do it)

Set 1 of 3 741's
power brick
usb cable
rasp pi
usb cable
dongle for translating usb to 4 pin signal.
four pin
avalon --1
four pin
avalon --2
four pin
avalon --3
a finksy 4k psu
------------------------------

Set 2 of 3 741's
power brick
usb cable
rasp pi
usb cable
dongle for translating usb to 4 pin signal.
four pin
avalon --1
four pin
avalon --2
four pin
avalon --3
a finksy 4k psu

------------------------------------

that dongle is hard to source.

when you buy an avalon

you get
1 dongle
1 usb
1 four pin wire
1 avalon

by using 3 to a rasp pi you conserve your translation dongles

Meaningful conversations like this one is the reason I love this place

I had no idea those USB dongles were hard to source. That is good to know, I can now plan for that.

My 741 showed up today a day early and it's happily hashing away. I'm very pleased with the turnaround from Canaan. What do you guys recommend setting the voltage and fans at to keep it quieter? I have it running in my home office and the ambient room temperature is about 78.

I tested

0 higher speed of hash fan and watts then -1 1200 watts
-1 higher speed of hash fan and watt then -2 1100 watts
-2 lowest speed of hashlowest fan speed watts. are lowest. 1000 watts

if noise is key -2 is the way to go.

Thanks Phil, I'll try that out. She's screaming right now, so I'll need to quiet it down or host it somewhere else.

Pretty much this, though in cooler temps I see a bit higher rates and energy usage, but optimal efficiency.

How is the hashrate and the wattage on the different volt settings?
