Title: s7 hashing drops!!
Post by: medo535 on June 01, 2017, 08:14:33 PM
Hi,

 I've 3 different batches of antminer s7 , they are working fine at antpool , but when I use it to mine in multi sha256 coins pools , I face hash drops then total antminer failure , I have to disconnect the electricity then reconnect it, it happens every few hours

I rented sha256 rigs then the same problem happened to the rented rigs , although I set the difficulty to 8192

I tried many things and the problem is still !!

Every time the miner restarts cgminer (aka switches pools) there is a chance a board will not restart. The simple fix is not to mine on multipools because there really isnt a way around this issue.

Thanks fanatic26, so there is no solution even from the pool developer side?

It has nothing to do with the pool. Its the S7 itself. Sometimes when you restart cgminer the boards dont come back. If you restart it again they usually do come back but running on a multi pool where you are restarting cgminer over and over exacerbates the issue.

try to use https://github.com/Stratehm/stratum-proxy
install it in a local machine, point your miner on and set up stratum proxy to multipool.
