Re: Antminer Z9 mini overclocked

If we crack open the firmware, can we adjust the individual board frequency ??

If you have a Batch one mini that is over clocked, set this to the freq you want the new one set to, save config file, then upload that config file into the batch 2 mini.

tinkering with Firmware is WOW! spookily freakingly scary!

I have a batch 1 Z9 Mini Il give it a wizz
report back

no difference, i uploaded the May 18 firmware onto my batch 2 z9's on arrival.. worth a shot.. but still dropping a chip on board 2

Hey htautosjay. Wanted to ask you if you had a copy of the first batch firmware from bitmain support site? I did not DL it back then and now they replaced it. PM me if you willing to share mate. Lets see if there is some difference in Voltage settings that makes it less stable. Although Im afraid its simply lower quality chips as I measured power draw for 4x Z9mini from 1st batch @700 and now 4x 2nd batch @687. Results are 1493 W vs. 1530 W. There might be a small diff due to different PSU eff but never that big!

Deffo yes mate il pm you now.. i have batch 1 firmware standard and batch 1 from my 17 sol batch 1 Z9.
I have been searching through the firmware for voltage, but cant find it... also in the kernel log it says for some weird reason set freq to 750.. This is even when i have the freq set at 600... no where have i set freq to 750 but the firmware is doing some strange things.. i think its either temp or as you say power..
