Topic: 7nm Avalon ASIC (A3207) • AvalonMiner A9 • 0.06-0.07 J/GH - page 3. (Read 3738 times)
Good news it will be interesting to see how efficient it is. Maybe a very early October release is in the cards.
Canaan has added the avalon9 branch to their cgminer repository on GitHub. It looks like the first of the A9 series will be called the AvalonMiner 921.
Options to tweak the voltage level ("--avalon9-voltage-level") and the voltage level offset ("--avalon9-voltage-level-offset") remain.
The A921's default temperature target appears to have been bumped up to 97°C. The cutoff temperature remains at 105°C.
The default fan speed percentage remains at 100%.
The OpenWrt firmware for the A9 series appears to be incompatible with earlier AvalonMiner models. This means that it would be not possible to run a mix of different generations on the same Raspberry Pi.
Release binaries for the A921 that incorporate the most recent commits from the avalon9 branch have not been released yet. The latest release binary of the A921's OpenWrt firmware is dated June 28, 2018 at the time of writing. The nexttesting directory is dated September 10, 2018, but is empty at the time of writing. This means that there could yet be further changes to the A921's cgminer code before its first release.
The A921's MM firmware, however, has been released. The latest release, at the time of writing, is dated September 10, 2018, and its changelog simply says:

Cool, thanks for the image. 
That's surprising, I haven't heard about their Litecoin miner before this.

I remember reading about the litecoin miner the same time I believe the CEO started talking about potentially building the TV's last year. They both shared a blurb in the write-ups.
I did inquire about it but never heard anything official. Up until now I hadn't heard of anyone seeing one for sure.
Where did you see it?
think I saw it on red's twitter
edit: ok, so the A9 is the same design as the 841s. I mistaken another case for the a9's
This is the unit they had at their press conference yesterday:

It looks just like the 841 models, with 1 fan.
They also showed a Litecoin miner and a TV miner.

Given the previous Avalon designs and assuming Canaan does the same for the A9 it should be very easy to make cold plates for these to use liquid cooling.
Anyone seen the sem liquid immersion cooling board for the 841 blades?
I am really curious if they make these available for the new 7nm hashboards as well.
IF they do, i definately go for a liquid setup and push the max out of the new 7nm tech. (depending on price naturally...)
Any news about the release date yet?

I thought people were already customizing liquid cooling like GPUs for these things, not necessarily immersion. Oh course I can't find pictures or a link right now.

At least mid Sept more likely Oct

I saw the new housing. It looks like it won't be cooled with 1 fan anymore. This may just be the miner to end all other miners all the way til the next halving

I like it, this may be replacing all of my other miners while doubling my output.

This is VERY encouraging!

You can get Canaan's products through one of their distributors, like the U.S. based Blokforge, with no MOQ.
I've ordered through them for all my Avalon equipment, and highly recommend them. Great service and
support.

I 2nd this endorsement.
If you're over in Europe. cryptouniverse is your distributor of choice.
I have a question if anyone on here wanna chime in.
at 1800 watts, this miner WILL be very hot. So far Canaan has been cooling all their rigs with just 1 fan. Which works with the 841s but I can testify that it is reaching a sort of limit here now. at 25-30C intake the fans are running 100% all the time and the 841s are only consuming 1300 watts.
Do you guys have any concerns with running 1800 watts on 1 fan of cooling without liquid cooling?

yes
it may not be ideal for a hot climate using air cooling in the farm.
ie your place may have an issue running them.
they may build more then 1 model.
maybe same case with less boards.
maybe shorter case with same board but less chis
efficiency would still be 60-70 watts a th
one model would be 18th other 27th
the 18 does 1170 watts
the 27 does 1755 watts
Keep in mind that the miner design will be slightly different and it will be cooled by one 140mm high rpm fan.

Um, go to the Canaan.io site and click on Official Partners at the top. It is a listing of all authorized distributors world wide. Using them you get lower shipping costs, no import fees, and most important - full factory warranty, though with Avalons it is unlikely you will ever need the warranty.
I looked at the Asia distributors a month ago. Their websites seem like it wasn't updated in a long time and the prices were horrible.
Blokforge looks good though and they serve malaysia, hopefully it isn't too expensive to ship.
I'm interested to buy this when it launches. But the MOQ and company account restriction is a bummer. If they don't solve this unfortunately my money is going to bitmain.
