It is really easy as I said, only cost you some minutes watching carefully your system. If your system crashs, YOU have to find why. Not the community, not CD.
Install latest NVidia drivers, clean up your system, reboot.
Open Afterburner and watch carefully the clocks when the miner creates the tree. Sometimes (not everytime) the core spikes for a second above 2100-2200 MHz (depends on your card, 1070, 1080 or 1080 Ti). If your card & PSU cant handle such spikes, your miner or even your whole system will crash.
How to fix? Easy!
Clock your cards down to a point these spikes wont matter (usually a spike clock between 1950-2050). To make this easier, download the official CCminer and make your system 100% stable with -i 20. The CCminer will crash much faster with wrong clocks, so you can save time by testing things out. When done, switch back to CD and your system is 100% bulletproof stable.
The problem is the miner itself is not showing it's crashing so there's no way to monitor it for crashes. Sure sometimes it gives an error on the miner but then I can downtick the OC there but often I have the miner showing it's still mining, but I can tell its crashed because it's the same exact hashrate total for 10mins. I look at the cards in afterburner, all GPUs sitting there with the stats that are fine. Its core is up, its heat is up, its power is being taken, but no activity at the pool. Both the miner and afterburner look like it's mining but the pool says nothing. This consistently happens.. Also the miner has a tendency to leak hashrate as time goes on even though the settings are the same. Sorry, but it's not the community that needs to figure out the prob, the miner has bugs and we can assist in pointing them out but that's the best we can do.
