@zigminer, i want to run 3009 firmware but why is it sooooo buggy? it works like 15-20 hours good and suddenly out of the blue a hashboard doesnt work anymore, yellow red asics, or a half hashboard is black. Sometimes you have to restart 5 times or more... BUT it is the only firmware that hashes 6.5 ghz for my z1 instead of 6... I am not awake 24/24 to monitor this.... i loose more money on the not or half working miner if this happens over night then install a new firmware that is less or more a bit stable. at least for a day ... Why is there only 1 firmware that hashes more ? Why is it soooooo buggy?
Try to replace your power supply
Many agents privately send some poorly performing power supplies.
We also found instability after our own tests.
if so,
dear @zigminer why did not you send a specific and approved psu with device, or suggest one of them that you approved like bitmain apw7++ 1800 w psu.
there are different problem also like i.e. they gave me a 1400watt psu with, but device make peak to 1500 watt at 900 mhz with 3009 image.
I had a serious problem with the PSU. After some time of working psu died and as a result the two hashboards faulty. They ve'send me the new psu (bitmine, which is much better) and two hashboards. Now machine working good, but time is lost.
