Would running 2 (2GB) AMD R9 270X cards in Crossfire, bypass the DAG limitations on VRAM size?
I made the mistake of thinking my single 2GB R9 270X running alongside my 6GB GTX 1060 would work out. However the DAG has exceed the 2GB limit as of this post and now I can no longer run both.
See output from Claymore's:

I have read Can you mine with 2GB cards or less? Thinking about the DAG issues already and I understand combining seperate cards in one mining terminal would not work, however my inquiry is more so about combining them on the physical level with SLI/Crossfire.
