also maybe you have recommendation ofr non EOM firmware for S7?
No, sorry. The only firmware that I tested for the S7 was hosted by Nicehash, and their website has been down since the hack. You'll have to search on your own.
The nicehash version of the Bitmain drivers allows the pool to switch you to mining anywhere at any time even any other coin without you knowing.
e.g. the pool can switch you to mine shares somewhere else, then back again, and you'd never know.
It's a major risk for miners to use the nicehash firmware ... as I've stated ever since they came up with that hack.
