Avalon A7 announced

[isoneguy]

Bitcoin is still accepted, correct?
What is the current shipping time after payment?
Using my own brand new Raspberry Pi would be okay correct, if they provide the image?

Yeah, you should just keep a backup pi around just in case.

The controller firmware dated 2016-Dec-29 ran the fans continuously at 4000 rpm so I went back to the firmware that came with it..... Nov something something..  I couldn't see any advantage to using the newer firmware (other then quicker ramp up time and noisy fans) and was hoping someone with a more complete understanding of the firmware could tell us the advantages of the newer firmware..Thanx

The older fan control would fail to control the heat... Newer fan control keeps it under 90 degrees if possible where the old one it can go higher despite not turning fan up to max. In cold environments the fan will now run slower but in warmer environments it will run faster. Depends on whether you care about noise or the device lasting...

See this code.
There is also a 88x A3212 chip version of the Avalon7.  
Canaan Creative AvalonMiner 741.

This is getting real really soon?
Maybe a more efficient model or just with a greater hash rate ?

Looking forward for this

Can anyone from Avalon confirm they still have units for sale?

Um, have you checked their website?......

Hi all,

Just wanted to inform that I have an underperforming unit and was communicating with Canaan back and forth with troubleshooting and software updates but still no fix for it.

I have 8 units and only one is underperforming.

Canaan offered me a new unit free of charge and free shipping!!

I accepted and they just processed it to be sent!

And I keep the underperforming unit!

Best service ever!

I just tried it. They laughed at my face. I don't get it.

How reliable they are? Better tan S9. Or also dropping like flies

rocksolid

S9 is expensive electronic waste (judging from my B1 units, after a half year ~50% have some kind of trouble)

[kurbeks]

Keep for now and add more A7. Antminer price (at least S9) won't go down, becuase A7 is far less efficient than S9.

Canaan Offered me a lower price on a canceled order if I order it before tomorrow.....hmmmm

Same. Still doesn't seem worth it though. ROI is quite a ways out with that speed. Also their shipping costs for 1 to my home is 180 dollars. A R4 in comparison was 65.

[kurbeks]

Like inno tries to make a living of shipping costs. or pushing for bigger orders Eitherway thanx for answers about reliability.

Different cooling. Airforming cooling technology. Hmmmmm.

[Rabinovitch]

There is nothing new in their shop.

[hhumaidan]

Send them an email.

They should open it soon since they constantly changing the website.

I hope the unit they sent me is the A741 instead of A721.

Fingers crossed.

I will receive the unit on Saturday.
