Innosilicon releases A9 Zmaster 50ksol/s Equihash miner at 620W

[imine2]

Want to add. I think its completely possible that these things constantly overclock and reevaluate themselves and inno's just making little (unsuccessful) tweaks to the process. Trying to stay optimistic tho.  

if it's possible to understand how than perhaps it's possible to "pipe to null" for values that make A9 decrease speed but I guess one would have to manually set fanspeed to make sure it doesn't overheat.

don't have one yet but just giving my thought so someone else with more knowhow can see if my idea can be part of a solution !

perhaps it's like antminer z9 mini where it seems like they have limited max power to the chips !?!?

Still want to watch not just your temps but power expenditure. Max profits will be more of a factor in coming months. Nice though to see market stable in the $30+ish/day range.

Hi everyone
I got some problem with A9
I charge password login A9. But now i cant login to manager page
How do i reset it ?
What's ssh password?
I have some A9 running ~3x ksol/s
One of 3 board just 7 8ksol. So can i fix i by myself  or send back to innosilicon ?
Other problem is
2 ->3 hashboard running 12->13ksol/s so total 3 board running <44 ksol/s
can someone help me
Im feeling bad right now

i don't have one but been following this thread if I should get one!

SPEED-problem:

TEMP
if ok...

Powersupply (APU) good/bad
if ok ...

try factory reset to get them retune speed!

Choose miningpool with low latancy
https://investoon.com/mining_pools/zec

(Ping miningpools you are using to check latency)

LOGIN-problem:
If A9 has reset botton on controller than perhaps it's possible to make hardware reset !?!?
else...

This could work!?


SSH
user: root
password: blacksheepwall


I suggest you use same hash as you will find in another of your A9 where you still can login and still know password OR use same hash as user: guest. meaning hash value for user: guest should equal password: guest
try to logg in as
user : guest
password: guest
(if this works than you know that user: guest has password: guest)

when SSH into another A9 do this:

cd /config
Press "Enter"-button
cat web-users.json   (will show what is in file witout edit capability)
Press "Enter"-button

(write down hash value for admin and/or crossreference that hashvalue for user: guest is the same in every A9)


SSH into problematic A9

cd /config
Press "Enter"-button
vim web-users.json  ('vim' = editor)  (You should google keyboard commands for vim-editor)
Press "Enter"-button
i    ('i' = insert mode) (NOW u can change hash for admin) (BE CAREFUL)

(when done do this)
Press "Esc"-button
:wq!
Press "Enter"-button
(You will get warning that read only or something.)
Press "Enter"-button anyway


(verify that your change has taken effect)
cat web-users.json
Press "Enter"-button

systemctl restart cgminer  (restart A9 from within SSH session)
Press "Enter"-button



If you used hashvalue for password: guest then you MUST remember to change admins password from 'guest' to something other!

Good luck!

[rapidleech]

it's still profitable to buy A9 ZMaster or Z9?
i have almost free electricity (0.02-0.03$ per kwh)
is it possible to achieve Payback under 4 month?

any advice?

I think you posted this in the other thread as well but you're probably looking at under a year ROI if market stays static with diff rise. Pending any bear or bull runs.

So you would not suggest buying asics?
whats the best algorithm to start mining with considering the future of market?

I have bought some A9s since Jun 2018 and recently, i am confusing about ROI. At that time, the profit was around $72 - $75 and now it's not good (you can check on asicminervalue.com). So i think, you probably should wait for one or two months until new generation asics. My opinion.

[jillscarbrough]

I hope you can achieve ROI but if A9 is no longer profitable, what will you do for that device? That's the weakness of ASICs if comparing with other devices, ASICs don't have resale values and ASICs are too fast in issuing new generations.

[Andartis]

Guys, depending on what you want to achieve, you could just buy the coins instead of buying an asic to mine them. In both cases, you can hold to make more profit. An ASIC ROI can not be calculated that easy.
Just one aspect: if you get 10$ from mining and pay 9$ for electricity, you make 1$ profit. If the device costs 1000$, its 1000 days roi.
If you bet on rising prices, you could also just buy coins for 1000$ and have the effects of rising crypto immedeately. You also decrease  your investment risk. Otherwise you invest 1000$ for the ASIC and 9000$ for electricity to get 1000$ worth of coins. If you dont change to fiat every day thats a pending risk of 10.000$. of course its just example. But think of it.

[chinguyensg]

Selling some GPUs to get back some money is no different from switching off the Acics and throwing them into the trash. Failure is failure, i think that.

I still keep my opinion that if we choose the right Asics, the right time to buy them, we still have the opportunity to collect profits. A9 is not bad if you buy it early.

[minefarmbuy]

If market bolsters I'll be turning on s7's for sha256 as revenues support it. Same goes for these so their are hardly trash worthy ever and with decent coins will have use in the future. Most likely these asic friendly coins will have some value with dedicated hardware like this. Someone somewhere will leave these running if there is some return, or they truly support the coin.

Buying now is gamble, only do it if you have capital to risk as profits will be shrinking. Buying now could also be speculation for a market surge and you'll have equipment running an able to capitalize on those returns early. Also a gamble.

Other options would be to buy to solo mine and gamble that way. Or if you already bought, solo mine if you can soak the power cost

There are reasons to buy and not buy. Mostly it's a risky endeavor at prices right now with market low and unit cost still really high.

He nailed it. This is a GAMBLE. You could go on Ebay and buy some miners that currently loose money daily. If the market surges then they will become profitable again an at that point they will no longer be for sale at cheap prices. It's just a glorified casino where the house doesn't have set rules to win 51% of the time. So that's it really. I have two A9's running on Nicehash, some days its 90 bucks, some days is 60, it market dependent. I have 4 Mini's running on Zcash, same type of numbers. If market goes up, make more, market goes down make less. So no one can tell anyone for certain if it's a wise investment. IMO, and we know what opinions smell like, for the Equihash miners I'd say take the money and invest in Stellar Lumen, or Bitcoin when the daily RSI bottoms below 30 which is coming over the next few days I feel. But I hope I'm wrong because I have these miners an hope they will continue to be profitable for a long time. It's up in the air and NO ONE can give anyone who ask for advice a correct answer. That's the truth.

Back when I played poker every weekend sometimes I lost with a straight flush, no wild cards, then sometimes I won with a pair of nines because I bluffed well. There is no bluffing is this but it's still gambling at the root. However I do believe in block-chain. I don't think my lil girl will be willing to wait for several days to xfer money when she is a adult 15 years from now. Things must progress, evolve, and become better.  The old institutions need updating and block-chain is the future, not forever future, but immediate future. Again that's opinion and I could be totally wrong.

Hi everyone,

I have a couple of questions to the rate of growth of equihash's difficulty level as well as the profitability level of the A9 Zmaster:

I have access to pretty cheap electricity (5-6c USD/kwh) and am looking into purchasing the Innosilicon A9 Zmaster since they have recently lowered its pricing in response to the release of Bitmain's Z9 but I'm a bit concerned the difficulty level might blow up uncontrollably once the Z9 floods the market and hurt the profitability.

I've read somewhere else on the forum that the release of Bitmain's Z9 ASIC will see difficulty level spike up to 60% per month going forward when historically it's only been going up by 20% per month and most recently less than 30% per month as per CoinWarz ZEC difficulty chart: https://www.coinwarz.com/difficulty-ch What are your arts/zcash-difficulty-chart

Considering both the Z9 Mini and the A9 Zmaster have been out for months, do you really think the addition of the Z9 will crank the velocity of difficulty level growth to twice what it is currently ie 30%pm -> 60%pm?

Also, profitability level of the A9 using Nicehash has dropped 20% in just 1 week:

https://www.dropbox.com/s/vx0oo99xtt22oas/Nicehash%20Profitability%20-%203-09-18.jpg?dl=0

https://www.dropbox.com/s/sk5pivi6l5wfib4/Nicehash%20Profitability%20-%2010-09-18.jpg?dl=0

That's a stupidly fast rate of drop! Will it continue to drop this fast? If so, in a month's time this machine will be barely profitable?

Any advice/tips would be most appreciated!

[MaximilianProductions]

Another part of the reason we are not making that much right now is largely due to the reduction in price. Difficulty really hasn't been that bad with with ZEC being at $120 as opposed to $150 that is where it is really hurting us.

EDIT: Also, does anyone happen to know if they fixed the memory leak issue yet? I have yet to upgrade to the latest firmware as some people had issues with it.

[mylucky]

Thats great performance. To bad about that 100pcs minimum order

Not fixed, and still goes offline frequently and has to be powered off/on again. Very bad.

Damn, that really sucks, check out HiveOS This ASIC is supported with the latest release, I'm working with the dev to get an issue fixed, when the ASIC crashes Hive is unable to remount, he says it will be fixed in the next release, I am seeing if he is able to add a auto reboot timer into hive that will reboot the ASIC totally after like 12 hours, still recommend you check it out, I use it for all of my GPU rigs as well. Still wish Innosilicon would fix this issue.

Hi bro! thanks for ur answer
What is this code doing for?

These steps, I hope, explains how to change the hash-value for user: admin into another hash-value for which you yourself know the plain text password like for user: guest and for which the hash-value should match.

And after a reboot, I hope, now making it possible to login as user: admin

Kind of "reset" the admin password to a known password IF it's not possible to restore to factory settings i any other way WHEN you forgotten the password to user: admin

As far as I've been able to pursue this without actually owning one myself this is hash-value for user :guest in at least one Innosilicon A9 ZMaster from batch 1.
"username": "guest"
"password": "b015aa9f37299ed52c30137d447f97b1b176b341145cf7fe5f9a92e89292e8db"

AND the hash-value above will make this A9 accept "guest" as password for user: "guest" (without the " " )

This, I hope, these steps shows and will do for you!
(I did not have the hash-value above when I first wrote this. Have actually seen it IRL.)

[MarkAz]

FWIW, I was just checking on the status of my Sept 10th order, and my supplier said that Innosilicon is actually raising the prices on the A9's for the next batch, and that it's supposed to be the last batch they're doing.  It will be interesting to see if this is accurate or not - with the revenue they're generating right now, it seems crazy to raise the price, but also it might be to the point that they're just not worth it to manufacturer so it's on to the next algo.
