Antminer Z9 mini overclocked

[ZEDIX360]

One of my board is not present or dies after overclocking at 750......they use to go ok for 1 week at 700   and when i try to jump at 750 1 board crash...So i put back the original firmware to try to repair it and nothing change...i wonder if it s the hashboard or the controler board....Any soluce?

Thanks a lot

It's a trial and error process. Your ultimate results will depend on which batch you purchased, how cool you're keeping the miner/room, and some luck. To troubleshoot, I always first reboot the miner and keep an eye on it. If it can't hold the freq that it used to be able to handle, then I try to figure out what changed. In all of my similar situations, the change was always the temperature in the room (one time I moved a miner to a hotter location, another time the A/C went out). Once I got the miner back to the same room temperature conditions it was in before, it worked like before. These boxes are a little finicky at the higher freq.

My batch 2 mini started off OK t 675 or so, but after days it went down, and now it's clear down to 662 or so, testing that now.

Yep, doesn't make sense to me because they never go above 70c. yet when they do die it's only during the hottest part of the day despite regardless of fan setting.

so why does everyone think they are entitled to this massive overclock on these?

People seem genuinely confused and offended that their machine can only overclock 50% over the advertised rate.

No one promised you anything but 10k sols, if you get even a fraction more than that you should be happy.

Instead people want to try and RMA machines that dont overclock enough for their liking?

where can i download a legit batch 1 firmware?

We managed to OC some of our Batch 2 devices up to 706 with stable hashrates for 19hrs. We are very excited about the results.

I am very upset by having invested in miners. I will never buy miners again. It's not worth. I have better solutions to invest my money. Losing time, money and effort for a too low and long return in time. So the true is save your money and invest in better stuffs.
I overclocked miners ,  I tried everything to maximize the return but again is not enough.
Save your money, save your time, don't buy it.

[God is back]

Stop buy chinese stuffs, absolutely not worth. Buy National stuffs, they steal your money in favour of communism capitalist.

I'm quite sure thoose who sold us the ASICs are true capitalists and the money will go to their Globalist Totalitarianism of which Communism is just a light version. It's Agenda 2030 and beyond their goal is at.

Just hope WWG1WGA WW will succed!!!

(Q = red pilling and waking people up and draining the swamps)

You are right bro. Time is coming!
I've been stupid to buy chinese again. But I vow that I will not be anymore prey of the communist Chinese.
They are and will be always my first enemy. I hate the communism capitalist of these people not able to create added value. Thinks about the salary of people that is building asics in factories. They are trying to build a new Roman Era with their modern slaves. But pay attention Chinese, in the Roman Empire we have built streets, aqueducts and a big army ready to fight anyone. Not to build obsolete miners. Also the Moore's Law, do you remember the famous 18 months in ICT? Well, with these new miners this law has been destroyed.
Pay attention chinese, or the Old Empire will destroy you.

It seems that communications on Z9 is done through PIC16F1704, same as for L3+

Did anyone try to change voltages similar to this ?

Code:

./set_voltage 1 90

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

There is no sticker over the fan. No one will recognize, you had it reversed. But i just do not see the point of doing so .)

FYI: with those 2x Z9 from batch2, i§m not able to go over 600MHz, when i overclock more, they runs just about 1.5 KSol.,.. Asic status is oooo for al boards
Doesnt matter if i set 610, 630, 650 or more, looks the same

Something as:
Chain#   ASIC#   Frequency   KSol/S(RT)   HW   Temp(PCB)   Temp(Chip)   ASIC status
1   4   666   1.62   0   33   41   oooo
2   4   666   1.27   0   33   41   oooo
3   4   666   1.39   0   35   44   oooo

Compared to 600 MHz:
Chain#   ASIC#   Frequency   KSol/S(RT)   HW   Temp(PCB)   Temp(Chip)   ASIC status
1   4   600   4.30   0   50   64   oooo
2   4   600   4.09   0   46   60   oooo
3   4   600   4.62   0   49   61   oooo

Seen the last returns ready to turn off this great investment 
Damn China!!

 you can try google but here you go
BTC is BTC altcoins are al all the other coins

Could you pls help me to figure out how to solve the problem on board no.2 ?
I have x on board 2, however, if i decreased the frequency the x will be removed.

"Decrease frequency" is the only solution as of now.

Does board no 2 get enough power ? ? ?

Switch powerconnector with board 1 or 3 and see if problem moves to other board or goes away ? ? ?

If not, then decrease frequecy is only solution as of now!!!
