just 1 hour earlier, i got DAG error when mining ETH with RX570 4GB (my rig have 6 cards). i already set virtual RAM to 40 GB but it still keep telling me that DAG ERROR

Cannot allocate big buffer for DAG.
Cannot write buffer for DAG.

Any idea please?

I've gotten this error before and it was basically due to not enough system memory (RAM) not Graphic memory (GDDR) or Virtual Memory.

If you got 2-4GB of memory, try adding another stick from another rig and see if it fixes it. I am assuming it will. If it doesn't work then just install Ubuntu and you shouldn't get this issue.

Solution is add to bat file command -eres 0

I confirmed this works for me, thank you

Note that "-eres 0" will work for two more epochs only, so you will see the same problem in a week or two.
I prepare new version, it uses a bit less GPU memory so it will add a couple of weeks too. Anyway, for cards with 4GB or less it's a good idea to check other solutions like installing more physical RAM (if it helps) or changing OS to Windows 7 or Linux.
