EDIT: Apologies Mr. Natural, you haven't made a typo it seems. As i've now seen other reports that users were getting NA All 2014.40 to work on 3xx/6xx units, in spite of it being 2.10 GiB and well over the 2Gib limit, I've done an experiment and found that it does in fact load and work on those [supposed] 2GiB limited devices. I'm a little confounded by this and it defies explanation. The 2.16 GiB 2015.10 as expected doesn't work. Why one and not the other? Anyone able to explain this?
Well, Neil, it looks like you're gonna get even more confounded: my 2015.10 NA All *.img file is, indeed, 2.16 GiB (2,329,477,120 bytes), and like the previous 2014.40 NA All version, it works just fine on my 660. Maybe the Binary Fairy touched my unit with her wand...
