Bitmain launches the Z9 Equihash miner

[greyday]

If I buy one, is it still profitable to mine?

If you actually use the heat, absolutely! If you're just venting it outside, then nope.

I heat my house all winter with miners, I haven't had to turn on my heater (also electric) since winter 2016. So for me, running an S5 in a cold room is technically profitable.

I think I broke my Z9 Mini.

The fan is not getting recognized anymore:

Oct 11 21:36:21 (none) local0.notice cgminer[1335]: No Fan find, check again
Oct 11 21:36:22 (none) local0.notice cgminer[1335]: No Fan find, check again
Oct 11 21:36:24 (none) local0.notice cgminer[1335]: No Fan find, check again
Oct 11 21:36:25 (none) local0.notice cgminer[1335]: No Fan find, check again


I worked with a fan faker before the miner is not even responding when the original fan is attached.

Is there a work-around to disable the fan check or do I really have to send it in to bitmain?

You have more then one connector on the controllerboard for the fan!

Have you tried other fan connector
any loose cables from fan?
jiggle them little if bad connection in contact or cables.

if nothing else perhaps you can buy controllerboard on ebay or somewhere else

good luck!

Try another fan before looking a new board, the control board is kinda spendy unless your under warranty. Buying though would have you hashing sooner if needed.

Yes, I tried the fan2 connector but still the error. Also I tried other Bitmain fans but still the error occurs.
I also flashed the new firmware and resetted the miner completelly with no change.

I am in contact with Bitmain about a replacement but this can take time and the difficulty is rising ...

guys, between the bitmain Z9 and the innosillicon A9, considering i have free electricity and buying price is not a factor to take into consideration, which one would you chose?

i know the obvious choise would be the A9 because of more hashrate, but actually overclocking the Z9 you can get more hashrate, no?

Yes, connecting RPM signal from fan to the 12V pin kills the board or at least a part of it and fans are no longer recognized
Did you have any luck with Bitmain?
If you have 4 x Z9 mini, you can connect 12 boards to 3 controllers

[grinbuck]

If you have 4 x Z9 mini, you can connect 12 boards to 3 controllers

Interesting. Have you tried this?

I have not personally tried it, but I can confirm the code will attempt to initialize 4 boards.

I've tried all available Z9 and z9 mini firmwares on the Z9 mini
Z9 mini firmware from May 26 - works fine with 3 boards only + overclocking
Z9 mini firmware from August 31st - works fine with 4 boards but no overclocking above 550Mhz
Z9 firmware from August 28th - works fine with 4 boards but no overclocking above 550Mhz and all temps are messed up
Z9  Efudd's Custom Z9 OC Free - works fine with 3 boards and no overclocking above 575Mhz and all temps are messed up
Z9  smartass111's Free Unlocked - works fine with 4 boards + unlocked overclocking but all temps are messed up

Jason, do you happen to know which file needs to be updated to enable the 4th board on Z9 mini May 26th firmware? I hope it's not the cgminer.
minerStatus.html will need to be updated as well but this one is only responsible for displaying the status.

Please do not run the Z9 firmware on the mini.. Yes, I know people are saying it is working, but it really is not working the way you might think. There are certain conditions where during a retry algorithm, it will just stop functioning until the next reboot.  The reason for this is the number of ASICs expected is hard coded in each binary.

Mine works fine with 4 boards, just only 3 are listed.. at least, that's what I expect. Someone else tried it as I only have a Z9 here at the moment and 3 boards.

.. so to answer your question, I expect just the status HTML. You can verify yourself by simply calling the API and/or looking a the logs to see if "4" chains are brought up (0-3) or just 3.

If you are running my 575OC on a Z9 (not mini) and the temps are messed up, then I would like to know about that because you are the very first person to say that out of 1038 downloads (as of this response).

Thank you,

Jason

I apologize for the confusion, all my tests above have been completed on a Z9 mini so absolutely no objections on the work you have done with your custom firmware, in fact, great job!!! And good luck with adding additional features you're currently working on!
Back to Z9 mini firmware from May 26,with unlocked overclocking, only the fist 3 boards are hashing, the fourth one connected to the fourth connector is not displayed in stats and not hashing, the board/heat sinks  are cold so it's not hashing at all and updating only the HTML didn't help.

Hmmmm. Ok. I'll add that to the list of things to take a look at as I get closer to making a mini firmware. That should be easy to unlock.

[adrian5]

would someone have the courage and open their Z9 (not mini) and make a couple of detailed pictures of one of those hashing boards? I would pay some Zcash for that. PM me

[efudd]

Z9 Unlocked firmware version 2.0 is available now at https://bitcointalk.org/index.php?topic=5036968.0 -- this version is dev fee supported. In addition to the excellent overclock benefits, it also now provides the ability to control the overclock of individual hashboards -- a single slow board doesn't have to slow your whole system down anymore! More features will be coming soon, as well as support for the Z9 Mini.

Thank you!

is there any firmware to fix nicehash mining with z9 mini>?

No just for the A9 that I know of.

what is the problem with zcash fork?
my zcash not payout last 2 days and my jaxx wallet not updating anymore?
what should we do?

I still get payouts. Pool -> binance receiving address.

well this voids the warranty. I just used my warranty to get a new controler board.

Jax has to do some back-end work to work with latest Zcash changes. They say it will be done this week. Your transactions should be safe and will show up after they are done with the changes.
