Hello,

Trying to set up multi gpu system.

8 NVIDIA 1050's and 5 AMD RX470's on Asrock H110.

Was working well with 8+1 but after adding the last 4 the miner now hangs on startup.
Tried versions 9.7 thru 10.2, no luck.

Is there a claymore GPU limitation I am missing?  All cards are installed properly in windows and patched blockchain drivers for the AMD.

The nvidia are a bit older drivers but seem to have the best luck with them for many months.(newer ones were not stable).

I tried the -gser settings but just delayed the hang.

Claymore loads the AMD cards, and them pauses, then eventually locks the entire computer.

Any ideas? 

Thanks so much!  Any suggestions are greatly appreciated.
