I have removed core and memory overclock settings as you have suggested, and the same thing have just happened again...less than 2hrs into mining with the new settings.  Checked the logs again and for the 2nd time today it seems to be triggering when generating DAG for epoch #0... why??

I checked my GPU temp logs from GPU-Z and it only maxed out at 56degC, but my Afterburner temp settings were set to 65degC, which matches my -tstop settings in the miner config parameters.

will this fix the issues I have described above?

Win10 user here with a single RTX 2060 Super, and 24GB of virtual memory page file already configured on my gaming PC.

Recently upgraded to Phoenix Miner 5.2e for testing on Nicehash & ETH on Ethermine, but I am still getting the same problem as before when I was on 5.1c - Phoenix would simply crash at random with no warning or errors after several hours of mining.  I have looked at the logs and the common theme I've been seeing is that it crashes during the DAG file creation process.  Below is a sample of the final moments as captured by the Phoenix log just before the miner crashes.


This problem also occurs at random epochs, regardless of the pool, or any -eres or -lidag values I use in the config file.  I tried to mitigate this with the -rmode parameter (wdog is enabled by default) but it does not work.  The problem also manifests itself with or without the NiceHash Miner client running....

The OC is what I would consider relatively mild - 1650mhz cclock (+100) / 765mV vCore (53% power limit) / 7650mhz mclock (+650), and has been working very stable for me in the past.  I have also specified -nvdo 1 on the config settings and also rolled back my NVidia drivers back to v432.00, and I also confirm that the Phoenix Miner EXE file is on my AntiVirus exception list. 

I am at a complete loss and appear have hit a brick wall (yet again) - any suggestions or ideas on what else would be causing this problem?
