I got my 2nd batch of z9 mini today. None of the 4 miner from this batch can hold 700 mhz clock, they can do 650mhz at 14.1k sol/s. Still fine tuning them for max hash rate.
2 miner from the first batch easily does 750mhz, 16k sol/s.
Anyone has tried to record backup of the first series?2 miner from the first batch easily does 750mhz, 16k sol/s.
