And out of that 3.5 gig, subtract the program itself, then see what's left for other things. Virtual instruments can quickly gobble huge amounts of RAM. Some VSTs like convolution reverb or Melodyne etc.,same thing. So, as Mario requested, let us know more specifics. It could be any and all of what you suggested.

I, too, have only 4GB RAM and never see that error, so I don't think it's all caused by BIAB.

By the way, are all your drivers up to date, especially video cards?
