Is anybody else experiencing nvOC hang / lockup to the point of needing a hard powerdown when Genoil crashes? I can log in but when I try to close the miner and shutdown the OS becomes locked up. I am wondering if it is hardware related? I am only using 4GB of ddr4 is that enough??? I believe I will be going back to Claymore. I can't seem to get Genoil stable even dialed 300mc back from Claymore. I will reimage a USB stick and go back to Claymore to see if stability comes back.
Having more ram would probably help; I use 8gb on most of my rigs and I have achieved multi day stability with the ones that are using genoil by previously lowing the clocks / adjusting the powerlimits whenever a soft crash occurred.
On a 4 x 1060 rig I use 1.1GB of RAM. On a 6 x 1060 rig I use 1.3GB of RAM. Unless there are spikes of memory usage or a memory leak somewhere, I don't see why 4GB would be more than enough. It certainly shouldn't have any effect on Genoil stability. Genoil seems to give comparable/better hash rates even with lower clocks and power limits than Claymore requires. I've found that dropping the clocks has definitely increased stability without reducing hash rate.
With Ethash more ram up to 16gb will increase stability. It is not that you need this much; but that: it will decrease your failure rate. You can empirically verify this, but if you want to use 4gb of ram go ahead. Using stable clocks and powerlimit will have a much larger impact on stability. You can probably reach marginally higher levels of stability with more ram.
