running ubuntu 18.04.1 with 13 RX570 (8GB) cards.

There is something seriously wrong with the Equihash 96.5 (Minexcoin) algo on v0.4
If I use the WORKBATCH:  HIGH setting, the hashrate slows down to a crawl, also of note is that the power draw of each GPU is around 40 watts (it's normally 95 watts when mining). Something just isn't working right with the HIGH setting.
If I use WORKBATCH:  MEDIUM, the reported hashrate (on http://eu.minexpool.nl) is around 10-15% higher then with v.034
However, it goes through these long periods where very little crypto is actually paid out from the pool. I don't understand how the listed balance for this rig is consistently really low, but yet the hashrate is high.

Switched back to v.034 for now.
v.034 doesn't have issues with '--set-work-batch HIGH ' , and it gets paid more from the pool than with v.04

Reassuring to hear something happens...
However No ZEC yet.  😡

Go the same issue with ZEC withdrawal from Poloniex... The transaction ID cannot be found on the ZEC block-chain - therefore is invalid. The funds are gone from my account. Ticket still not responded after 20 hours.
However, what's more intriguing is that a very small amount of ZEC I withdrew before went through with no problems. Hm... Not sure what's happening here.

Anybody tried recently to get ZEC out of Poloniex ?

Already did it at first, but it goes through the same story - staking=false.
