hello to everyone

i bought the 23/10/2018  Z1+. from the very first beginning i started to use it at nicehash pool. the problem is the it never-never go on average above 6,57gh/s. they promised 7.2gh/s. wtf is going on here?

i overclocked it to 1150 frequency. nothing was improved. i overclocked it with putting auto frequency to "1" at miner.json file. again nothing happened.

i dont know what to do to increase the hashing. this is rediculous. from the asicminervalue.com profit prediction, i am behind 3-4 euros.

can you please advise how can we overclock this thing?

i am using 20181015 firmware. it came with this firmware installed.

do you think i have a difesient asic miner? is it problematic or it is natural this hash rate?

at what gh/s do you have your Z1+. please reply only those who have Z1+
