AvalonMiner 921 released - 20 TH/s @ 1800W

[fanatic26_]

Anyone heard anything about a more efficient miner?

Avalon has always lagged in the efficiency department but they are on the cusp of just being an afterthought at this point.

nope no info at all.

if this units drops from 20th to 18th

and watts drop from 2100 to 1600  it would be a nice start.

It would be nice if their fpga firmware was open source as it used to be on github a couple years ago. What is AVA9_P_SET_SS_PARA_EN? Why even bother posting a changelog?

I've tried emailing the contact listed on their downloads page (love@...) but it's returns a Delivery Failure Notification. Do they have a dev contact?

Nothing notable, I honestly thought they would be announcing or taking orders for the elusive 941 by now. I'm only a few months out from having all my Avalons offline and replaced by M10's.

I never did buy anything in the 9 series, the value for me just wasn't there, and by the time it was something else was better. I'm still looking forward to any announcement, one would assume they have something coming, considering they still have a sales team.

[fccs]

I honestly think they are waiting for a market swing up.  Remember their scrypt miner as well?  Never went on sale.. or the 30th 9 series they promised as well.  Not sure what avalon is doing, I usually prefer canaan miners over everything but I skipped buying from them last year due to no point or barely any improvement...

[minefarmbuy]

Still great products if your power cost is low and with the prices they have right now canaan is the best deal $/Ths wise. So if you're looking for a cheap build out with a great deal on power cost very viable. Though yes, I think we all had some great hopes on competitive unit last year from canaan.

[MoparMiningLLC]

for me anything in the 80 j/th range is borderline profitable/unprofitable so I am going to be happy when my T15's get in.

[minefarmbuy]

Yea nothing I have is profitable anymore. About $0.60 loss a day. Will soak what I can and looks at upgrades soon.

[MoparMiningLLC]

my s9's are borderline - all depends on BTC value. I think if it drops under 3500 I am going to be in the negative.

[Elphamyto]

If the 921's firmware continues to be tweaked/tuned, the power consumption of the 7nm A3206 chips could probably be cut down, making this miner profitable.

I gave up on firmware upgrades. I just tried the latest updates and they bricked both of my units again. cgminer never even starts and doesn't show in process list. I had to revert back to 09-26-2018 firmware.  Nothing after October 2018 works on mine. If they ever do come out with a low power firmware I'm hoping it works on mine but I won't be surprised if it doesn't.

With the A9's it seems that when you upgrade the MM firmware you must also upgrade to the latest OpenWrt controller software. Different versions do not play together.

[philipma1957]

yeah I wonder if they lost a software guy as the firmware/software for the A851 and the A921 has not been as good as the A841's software/firmware was.

It is a shame as I like working with Avalon quite a bit better then doing anything with bitmain.

They may continue to improve the efficiency through the firmware upgrades. It just won't be enough to really matter unless you already own them and are borderline shutting them down.

They are going to hit a wall eventually, just not sure where they stop. I would think to really compete again they'll need a new chip design.

Borderline shutting them down? Hell, I have 3 offline now and 2 of those are still in their un-opened boxes as the M10's I've been getting blow the doors of the 921's...

Do remember that the A9's are using bleeding-edge 1st-generation 7nm process tech. Given when Canaan did the layouts (middle of 2018) it is a very safe bet that they will need to respin the design to substantially improve on current results.

I'm really hoping that they will be able to catch up with the power efficiency.

Yes you made a wise call there jumping to the M10's. I never dis grab a 9 series even after the price drops, just never made sense with what was coming out.

I can't remember, were they the first production of the 7nm? I did start to wonder a while ago if they aren't working on a new design and that's why we haven't seen a better model yet. I do keep checking in hoping to see something awesome from them to get excited about.

Hello dear, pleace tell me the best firmware and settings for avalon 921 and Raspberry
for maximum hashrate.

I gave up on this unit  I have it set that it does about 1800 watts and 19th

I think -1   there has been new firmware  but I do not think anyone has been able to get it to do much better at the watts per th level.

Does anyone have this  doing 80 watts a th at any setting?  If so please post screenshots  and wattmeter.

On the good side if power is cheap it is really reliable  at 1800 watts and 19th.

[fanatic26_]

Hi I want to find the maximum hash rate, not taking into account power consumption/

The very first post states the speed of the unit....

Specs:
Avalon A921
20TH/s -5% ~+10%

[NotFuzzyWarm]

And for speed/power usage when tweaking the A921, refer to here where I had ran tests on it. Also has some 741 & 841 info in there.
