You say you have plenty of power, which 3400 W is plenty, but you fail to say how it is being supplied. Is it one big server PSU, a server PSU and a normal desktop PSU, a couple of desktop PSUs?

From the limited information given, my suspicion is your problem is power related for the simple fact the Zcash algorithm usually draw a bit more power than mining Ethereum. So depending on how your cards and risers are being fed, maybe that little bit extra power draw is causing your headaches.

ding ding... you sir are a genius! Shocked

i moved some cards around and got 9 working with zcash - but anything after that blows the breaker in the house (15) Cry

right now i have 11 cards doing ETH no problem. last 1080ti tomorrow and taking the rig to work.

i have 2 1200 server ps and 1 evga 1k.

will have 3 1080s and 1 1070 on each 1200
and 4 1070 on the 1k + motherboard

leave a wallet address and i will send you some coin for the help...or else i would of been down there all night Undecided

If you are using a server psu it's most likely rated @800-900w on 120v. You would need to put it on a 240v circuit to get 1200w out of it. Just FYI for the future... your EVGA can run on 240v as well and will become slightly more efficient too.
