Driver version 430.40 on linux. You're right that mining to an ETH pool is more stable and as far as I remember never has this problem mining on ETH pools... however, my question here is why the rig is not restarting since the Watchdog was triggered?
If it's restarting, then i have no problem, loosing only some seconds to mine, but if it hangs up then it burns electricity for 3-4-5 hours maybe....
That's pretty old driver I recently updated my driver from 450 to 455 Nvidia version.
Are you paying cheap Electricity? I can't able to reach the 52Mh/s but I got around 49 with your setup but it's not profitable I'm wasted too much power compared to my setup with 44mh/s t-trex just got some idea from your setting and it works with PL: +160w
I more than happy if I can get around 48mh/s with PL:+160
