Well for some reason my rig just won't work properly with MRR. After lots more tinkering and troubleshooting I ran it direct on a pool for several hours and it showed just two network errors, but connected to MRR it disconnects every couple of minutes. Once it's disconnected it can show no hash rate at all for a few minutes until it finds the next share so average hash rate is terrible. I've tried all the EU servers and they all behave just as badly.
With Cast-XMR I can run a separate instance for each GPU. The one connected direct works just fine and the one connected to the
same pool via MRR still falls over every couple of minutes
I'm going back to mining direct or Nicehash since its not worth the stress of having to constantly babysit MRR. The Vega fans winding up to 5K rpm every few minutes as they restart is also highly annoying!
Oh well. It was worth a try
Worth mentioning, I've got it running at almost 4KH/s in Cast-XMR now - the average is 3980 with each card regularly hitting 2K. Total rig power is 480W including 10W for the CPU which is still mining ETN. I haven't done the sums to see if the extra 2-300 H/s are worth an extra 70W but its pleasing that after all the hassle I had at the beginning, it does actually do what it said on the tin
