So I am looking for the software link as the A921 will not work with a841 software.

poking around here is a no go so far

https://github.com/Canaan-Creative

this seems good
https://github.com/Canaan-Creative/avalon9-docs/wiki/AvalonMiner-921-firmware-downloads

Version 20180918

Download link Firmware - 20180918

I'm new to this and still researching but how do you calculate the cost of electricity, and where are the best countries to set up mining farms , or in general is it a good investment ?
MANY threads already exist for those topics. Use Search (or Google) to find them. This thread is regarding only the A921. It is not good form to sidetrack threads with different questions -- usually leads to mods removing such diversions...

So I ordered 1 Avalon a921  from blokforge.

No customs they handle it  cost me 396 paid it with a cc...

Likely duties/tariff is likely built into their pricing it just shipped from TX like they would be for our group buys from Portland.

Lucky. I somehow ordered one when they were first listed for $399 and price dropped $50 right after submitting. They credited back. No shipping notice yet though.

Still no word on when my 3 ordered Nov 30 will ship but I assume will be today or tomorrow. The two I got back in Oct. (at full price) are running perfectly at a rock solid 21.5-22THs each with 2x APW PSU's feeding each of them.

Don't know if anything has changed but Kano tried tweaking the one Canaan send him back in Sept and found that even using SSH to get in it pretty much ignored his attempts to change speed and other settings.

Yes, as long as each group of five 6-pin PCIe power connectors (there are two groups; one on each side of the miner) is connected to only one PSU.

Yes  that is correct.

I have a youtube video of the A851  with 2 psu's

... Is it possible to run the miner with two power supply´s?

A seller from Austria says this machine needs 95 - 100 Watt / TH.

So this machine needs 1900 - 2000 Watt.

I'm looking forward to your values.

Is it possible to run the miner with two power supply´s?

When did you place your order?  I ordered 2 on Nov 30 and 2 on Dec 1 and no shipping notice yet.

The sales price of $349 was hard to resist. Smiley

So I ordered 1 Avalon a921  from blokforge.

No customs they handle it  cost me 396 paid it with a cc.

I will hook it up and review it  some time soon.

it should do 20th at 1800 watts

I hope it will downclock  to 18th and maybe 1500 or 1400 watts

The A841 was a good  downclock machine

The A851 was really poor to downclock

I will post more soon.
