Ok, it is clear you are trying to help but please let this one go.
That source you posted is obviously outdated and clearly rookie targeted.
Mining is not the typical usage senario for desktop PC so please skip any article, guide whatever that is not specifically made for Cryptomining.
Anything below 20GB virtual memory will propably crash the miner. Even the OP states that VM should be 16GB or more.
I recommend he sets it to 25GB and try again.
Actually, when I decreased my RAM from 8 GB to 3 GB, I was facing some sort of application crash during mining (somewhat similar to @damba_'s), but decreasing the virtual RAM to 15000 MB worked out for me that time (it was way over this number before I decreased it). It's still running good at 15000 MB (just re-checked this number) with 3 GB RAM.
From what I can conclude, if you've over 4 GB RAM, you can set insanely huge values of virtual RAM like 40 GB or 50 GB (probably as big as your available secondary memory size), but if you've around 2-3 GB RAM, you've to set it lower and can't be that crazy.
Well that does not mean that it's because you decreased the pagefile that it ran better, rather decreasing the pagefile deletes it and recreates it. I am certain that if you went right back after to 15gb it would still work, proving my point. The amount of virtual memory has nothing to do with system stability, especially for mining where with ETH you need about 2.5gb of memory for each card.
Now on a 10 cards rig that's close to 25gb and you want to set a bit more for increase over time. I run mine with 60gb pagefile and don't have stability issues.
What you mention is what I believe you had instability issues in that pagefile and recreating it fixed your problem, the issue was not fixed by lowering it. See the difference?
