I also tried the Orange Pi 2W 1 gb memory version. Although rieMiner runs ok, the swap file is needed, resulting in about a 20% performance penalty.

I installed Arch Linux on the 1 gb Opi 2W and was able to run without using the swap file. Still about the same performance, 10% to 20% slower than 2 gb model. So I conclude more memory is definitely better.
