Troubleshooting

[CryptoSquad]

HI.

Im using 18 X Zotac 1070 8GB cards across three rigs. Each rig has 6 cards.

I am running Cyclenerds moded UBUNTU as my OS.

Every now and then Ethminer will just kind of hang. Im guessing its a crash but wondered how i am best to figure out the cause?

Again, assuming its a card causing the issue (They are all brand new), but how do i monitor which card it is? They are overclocked but seem to work really well in general.

How do i check for memory errors on the cards? Anything else i should look at? 

Thanks for any help in advance.

Thanks
