Bitmain launches the Z9 Equihash miner

[johndoe1337]

i received my Z9 mini 3 days ago, overclocked it to 743 about 5 hours ago, fan 100% (i dont care about the noise), temp of the cells is 58 celcius

so far i have an average of around 17 KH/s with peaks at up to 25KH/S


edit: also without overlocking it was around 11 KH/S, so it was pretty good even though it was running at 500

At aoutomatic fan speed it will let it go to about 70 degrees celsius and try to keep it there as max.
at 80 degrees it restarts.

Soo..

You probably don't need to keep it at 58 degrees.

Every degree will cost som fan speed?

try to find a sweetspot where it runs stable and save the fan a little.

Just my thoughts !!!

i thought about that but i did some research and found that having the fan set to 100% is no problem. It makes a very big noise but i dont mind, i guess only time will tell about the durability. Also If the fan gets fucked its not as much of a problem as if its the chips
i'll see in a few days the average, but when i saw it was doing peaks at 24-25KH/S i was like wtf

Whatever works for you!!!

What pool do you use to mine at when you get peaks like 24-25 KSols/s  ? ? ?

Success. I have overclocked my Z9 to 650... here's a picture of it at 600.

I'm going to let this 650 run for a while to check stability. The change I have made is hard coded at the moment, it'll take me a little longer to make something that should work for others... and even longer to make an image we can just install (maybe).

Definitely looking forward to what you come up with keep us posted

Anyone know how to fix a 'bricked' Z9? 

Yeah - read through a bunch of useless bitmain articles, piece together components, find the recovery for "V9-Tools.zip", pretend your Z9 is a V9, extract that V9-tools.zip to your 32GB or less FAT32 formatted SD card, power off miner, insert SD card, power on, wait for all lights but ethernet to go off (~60 seconds), unplug miner, remove SD card, replug miner in.

Then go find the Z9 firmware image and use the web interface to flash your "V9" back to a "Z9" while unchecking the option to "Keep Settings".

Once that reboots, congratulations, you now have 1 factory hobbled Z9 back up and running.

I'm running mine at 681Mhz now. At 700 the voltage regulators start to cut back voltage, power draw and hashrates bottom out. I haven't tested to see how far I can push past 681 that I randomly selected.

What I'm doing is lost on each reboot. I'm working to build an image that can be flashed to the Z9 that will let it run up to 575Mhz and will persist across reboots. My first attempt at a flashable image failed and until I can connect to to a serial console on these boards, I won't be able to troubleshoot it.

What bitmain has done is purposefully try to lock these down -- I'm still hoping to be able to restore the ability to select 500-750Mhz or so, but that is on the backburner at the moment.

My next goal is to build that test image and get some feedback. Given the fact that my last image bricked it, I'm going to have to connect to the serial on the unit and see why it failed.

I also expect that the tactic they have used here may apply to more of their product line... but one thing at a time.

Could see it happening on the mini's. A dedicated effort to reduce failure. Less warranty claims potentially? Better for their budget (since it's news now). Imagine any of these companies following these threads to learn to make their gear better or how a consumer prefers them.

[efudd]

Update: I've managed to remove the limits they put in place and can re-enable full frequency selection. I'm still working on building an image that others can test with.

Are you also adjusting voltage?

[efudd]

Anyone happen to know how to get into the serial console on currently shipping Antminer control boards? I'm looking at "Miner_Ctrlboard_V1.1" which is used in at least the Z9mini and Z9 (and I believe V9 also). I'm trying to use a buspirate right on the TX/RX/GND pins with no luck. I'm wondering if it isn't designed have it so you have to short something else on boot to enable serial terminal now.

Any pointers would be welcomed (I have and am continuing to search/try).

*EDIT*: Was able to get into the serial ports -- my buspirate was bad.. and  you have to invert the logic on the RX side.

... But now I am in at the lowest levels of this thing. More fun ensues.

If you are looking for coins to mine and a pool to mine it on, get on ZCL coin and this pool allows asics :

https://pool.zclassicblue.org/


Best pool i've found so far as ZCL is tricky to get pools working for asics

z9 mini and z9 compatible

lol  There is like... 2 z9 running on that entire pool at 100kh total.

New pool?  How new is this pool?  When I did a quick look it seems not many miners (only 9 right now).
What's your measurement that you use to declare it the best pool for you?

I've been testing a lot of big pools for zcl mining with asics and they arent configured right and get invalid shares on their end, this pool is created by the zcl team themselves and they designed it to work for asics .  Im posting it on here to get more people on it obviously I would like to see more hash but it is healthy atm and has 0 fee.

Alright -- I've successfully overclocked the Z9 and I can now build flashable images so the modifications persist across reboot. I'll post a new thread in Altcoins later today with a link to the 575Mhz image that others can test with.

Thanks,

Jason

Just got Z9 shipping notice, and US Customs bill for $900!

Could be the last miner I buy direct from Bitmain under these tariffs...

Thank you for keeping us posted as well as for documenting your process! I hope you'll add a link here to your Altcoins post when it goes up, very curious to try this out!

Folk,

I have created a post with information about the released firmware at https://bitcointalk.org/index.php?topic=5036968 - I welcome testing, feedback, and positive discussion.

As of that post, the 575Mhz version is available, and I will continue working on the fully unlocked version based on the feedback received.
