Antminer Z9 mini overclocked

[DepositBox]

I am certain I do not have the batch 1 and I am at 650, I was unable to use the firmware to change frequency so I used awesome miner.

Translation, and please feel free to correct me: You were unable to change frequency via the web interface, so you used awesome miner to change the frequency for you. Behind the scenes, awesomeminer modifies /config/cgminer.conf to set the frequency and restarts cgminer to make that frequency take effect.

I didn't say "only on batch1 hardware", I said "batch1 firmware".

anyway.

You are correct, except I did not change firmware, it's the stock firmware, I can send screenshot of miner when I get home tonight.

Is their custom firmware that helps with over clocks?

I guess it's a stock firmware BEFORE aug 30 2018 !
But from witch date would be of interest ?

Hi guys I did anything that You told, but it is not overclocked.

If you check this link that is in the posting before yours you can read that aug 30 and aug 31 firmware versions does NOT work to change the way you tried.

If you download may 26 firmware in link above and install you can use the web-interface like God intended and choose your desired frequence as everyone with a batch 1.

Try with 668 MHz if batch 2.

If problem go down to 637 MHz to try to find stable overclock.

Good luck!

t would be interesting and helpful to the community if one of these days you report to us if and when your Z9 ASIC dies. I would certainly find that useful information and reward you with some merit or some other way if possible.

"work for 30 days from october 10, 2018" means every 30 days I have to install firmware again ? and I don't have have to upgrade it anymore ?

let me know installing firmware is risky , I mean when I encounter an error during the installing what will be happened for it , because the old firmware is erased and new won't install , is there any other  interface without web that in emergency case we can deploy firmware file or bin file in it such as serial (jtag)
?

The LINK at uploadfiles.io will work for 30 days.

I did it and it worked, but I tested in 668 was good but in 700 the rejection was a lot and 725 in comparison 668 was not remarkable 668 is 14TH - 15.5 TH and 725 is 15 -15.8

In my world stability is my goal !

Getting max hashrate reported by the asic miner is not important.
Many other things will be of importance for end result.
Latency to mining pool
which coin(s) to mine
which mining pool

https://investoon.com/mining_pools/zec


Important is 24/7 stability with optimal hashrate !

End result matters!!!

i have got the same problem with my batch 3 mini.
Once i install an other firmware the temperature sensors dont seem to work and the fans always spin on 100%.

Does anyone have the same problem and does anyone have a solution?

Thx!

May 26 version and Aug 31 version are the only versions as far as I am aware that have been able to download for z9 mini from Bitmain's support site !

Have you carefully jiggled fan cables in connector on controllerboard or tested move fan connector to fan connector nr 2 ?

Hi,

it works just fine with the original firmware, so the fan cables are not the problem (nevertheless i checked it and also switched to the second connector).

I tried batch 1 firmware (the one you mentioned), result ----> works, stable overclockable until 681
BUT:
Chip temperature always reads: 0
Fan always spins at 100%
Changing it to 50% works for 10sec then back to 100%

Also tried batch 2 firmware, same results.

I also tried to unplug the fan while the miner was running and connect it to the 2. fan connector of a other Z9 mini but it stops working the moment i unplug the fan.

Which version is "original firmware" ?

When you install other firmware have you UNchecked "keep settings"  ? ? ?

[Zapp777]

The only one on bitmain homepage:
Antminer-Z9-Mini-NAND-500M-201808311812.tar.gz

I tried both, keep settings and also unchecked it.
Did it several times and tried every combination.

the only tiny success:
installing batch 2 firmware --> change to turbo --> keep settings ---> install original firmware
Result: 550 frequency + working temperature sensor + working fan

sadly this trick does not work with batch 1 firmware and (e.g.) 650 frequency.
Keeping setting and reverting to batch 3 firmware resets the frequency to 500.

I expect batch3 firmware may be restricted to specific frequencies like the Z9 was (guessing, not verified).. If so, then it makes sense that it would reset back to 500Mhz.

On first page under System - Overview:
Do you also have "Hardware version: 9.0.0.5" ?

Seems like you are stuck on 550 for now ?

Would not recommend doing other way around !

But if you install batch 2 firmware where you can change to 550, can you not use the trick with inspection in web browser and up the frequence to 650 and NOT change to another firmware ?

Newest firmware does not mean best firmware always!

OR could it work to install May 26 -> set 650 -> keep setting -> install batch 2 firmware    ? ? ?

[Waldooooo]

I have one Z9 mini September 2018 batch with firmware dated Sun Aug 12 17:43:41 CST 2018. Although the only GUI option is "Balanced", I can configure OC with web editor to any speed with the best speed being at 675 MHz and 95% fan speed for best cooling and is producing a stable 15-16kH/s hashing speed. I received three October 2018 batch minis today and the maximum OC speed in the GUI is the "balanced" setting of 500 MHz but can only be raised to 550 MHz using html editor. The miner will reject and revert to 500 MHz if any other number is attempted. Of course, the "Aug 12 17:43:41 CST 2018" firmware is no longer available on the Bitmain website which was replaced with the Aug 31, 2018 firmware which is what is on my new batch. I tried to save a config backup from the older device and restore to the new one but had no affect whatsoever. Did anyone happen to obtain the Aug 12, 2018 firmware before it was replaced and might it run as desired on the newer Z9 mini? The new Z9 minis are hashing at a consistent 12-13 kH/s at 550 MHz which is about 20% below the 15-16kH/s at 675 MHz. I may just have to live with that.
