I got that Goldshell KA Box Pro and it never hashed 1.6 TH/s.
The most I got was 1.56 TH/s.
After 1 month running fine, it dropped to 1.3 TH/s all of the sudden.
I sent my log to Goldshell and they wanted me to ship it back to Hong Kong by courier.
Problem is, I'll lose the miner for roughly a month before getting a new one, so 0 hashing, and courier from Canada to Hong Kong cost about half the cost of my miner.
Got mine for 459$ USD plus import fees.
I don't feel like paying another 200$ to send it back.
Anyone tried opening and repasting the chips?
