ME TOO 

Since the version updates, it's a disaster,
we try to save 4GB cards by doing hacks, instead of making a clean version for cards over 4GB.

I lost in hashrate, I have errors like Disabling DAG per-allocation (not enough VRAM) on 8GB cards ...

in short, people with 4GB are doing their time either he buys cards of + 8GB or mine other money but we should stop wanting to do the impossible ...
