1  Alternate cryptocurrencies / Mining (Altcoins) / Re: Help with reward!!! Mining problem on: October 12, 2017, 03:03:13 AM
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

H110 Pro BTC Motherboard
3400 W of power

GPU
5 1070 AMP
4 1080TI AMP

OS
Simplemining
Ethos

known goods
all risers
all cards
each slot on motherboard
enough power
bone stock no overclocking or adjustments

problem.
each OS will recognize 9 cards no problem.
when mining Zcash with EWBF - it will mine fine with 8 cards all day no crashes but when i add a ninth card it messes up from BOTH OS
now... when mining ETH from ethminer - ALL 9 cards will mine fine all day no problem.


update for today
I am heading home to install another 1080 and 1070.  another 1080 by tomorrow Smiley

I have seen videos (youtube) of people mining successfully with 12 gpu nvidia cards using simplemining and I assume EWFB miner (they dont show that but it looks like the only miner for that?)


any suggestions ?  if you can help me figure wtf is going on.. i will gladly donate to your wallet  Wink
