My Z9 mini has been running for 44 days straight at 750M with an average sol rate of 16.37. I have seen my Zcash per day steadily drop for the last few weeks and is now at 0.0927 Zcash per day. This machine has been great but it looks like the full size Z9s have started to come online and the hashrates are going up big time. ![Sad](https://bitcointalk.org/Smileys/default/sad.gif) Fun while it lasted! 0.0927 ZEC per day? Lol. where?

I just received my Z9 Mini from Batch 3 ($793, Sep 20 - 30th Batch). US, DHL delivery, no customs.
It seems they have fixed the workaround for overclocking or used a different firmware on this batch that locked down overclocking even more. The filesystem/firmware is dated Fri, August 31st rather than Sun, Aug 12th like Batch 2. When attempting to use the advanced editor 'F12' and change the frequency manually it just ignores the change and chugs along at 500 freq.
I'm seeing around 11 ksol/s with no OC currently. I'll have to try another work around later like flashing an older version of the firmware.

There is no magic to it, just flash batch 1 firmware and you dont have to do all that random editing and whatnot, you can just select from a drop down menu. I am curious to see if the batch 3s are even less overclockable than batch 2 or if they have just settled with this configuration as final

Guess now we know why they delayed the shipment. Had to patch their hole. But the real question did they lock flashing the firmware too?

It's only been running 10 minutes so I can't speak to how stable it is; but my batch 2 units will crash almost instantly or 2/3 boards refuse to start hashing above 673 freq. My batch 2 run at 625 freq for about 13.75 ksol/s stable because I had some boards crash with some units even at 631-650. I will edit this post if I experience any stability issues. Batch 3 Z9 Mini15 ksol/s stable @ 750 freq PCB Temps: 64*c ish Chip Temps: 70*c ish

Hello guys
i just got my two z9 minis a playing with overclociking. What will happen when i overclock and miner won't start? Is the reset button enough (or what does the reset do?) or do i need to re/upload firmware?

If your overclock is too high the hash board will crash and give you a 0 reading, just go into the overclock settings and lower the setting and hit apply and the miner will restart with the new settings. Some people will start at 650 and go up step by step until it crashes. Keep in mind that when ever you get close to the sweet spot it might still crash. For instance mine will run at 675 for about 6 hours then one of the boards crashes. At 668 it will run for 12 hours and crash. Best setting for mine is 662 and has been running stable for 6 days with out any problems. I have a batch 2. hope this helps.

SOlved No need for a 2nd fan, just reverse your current fan so that it pulls air instead of pushing it through the unit and the miner will run about 10c cooler. Because we don't have a second fan... ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) How reverse the current fan inside? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) Just did, Let's see how that works. Is possible enable the second fan too? Because we don't have a second fan... ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Solved

Best setting for mine is 662 and has been running stable for 6 days with out any problems. I have a batch 2. Also unscrew your fan and reverse it so that it pulls air instead of pushing the air. Mine went from 60c to 50C. I also run the fan at 55% instead of auto fan. results may vary depending on your ambient temps. Mine is in the basement where its pretty cool all day long so just keep an eye on the temps during the day and adjust your fan speed accordingly. I ran all of my miners at 50-65C. hope this helps. Reversing the fan is a bad idea, see here - https://bitcointalk.org/index.php?topic=3509006.msg43559339#msg43559339Let the original design be.

Batch 2 can be overclocked as is with F12 on your browser . Looks like batch 3 cannot untill you flash it with a batch1 firmware

Anyway I overclocked with the old firmware to 718 frequency. I get this
ASIC STATUS Chain 1 0000 Chain 2 X000 Chain 3 0000
I tried everything to restore to have all the chains working. A Perform Reset, a Restore Backup and recharge the new firmware but nothing that can work. Seems under 650 all the Chains give me 0000 but is not worth. So like told previously at the moment NOTHING can be done to have all the Chains working with an HIGH FREQUENCY except that lower the frequency. Otherwise the other miner give me all the Chains working with a 687 frequency. It's a mistery really

Anyway reverse the fan will fall the warranty. So make it at your risk.

do not reverse the fan. the temp sensor is on the far end of the board where the air exhaust out of and if you reverse the fan, cold air will hit the temp sensor first giving false cooler readings so the fan will slow down and be more quiet but your chips will be running hotter than reported in the GUI. i know we all hate bitmain but they didn't make an asic to fail and die to get warrantied back.
