Hi, mine came with version 1401 dated 28/08/12, hope this helps.
Hi, as far as I'm aware if you install an fx6300 it will still work even with the older bios, it will just not recognise it, so even if it ships with older bios you will just get no cpu details and maybe some instability. It usually thinks its an older cpu so doesn't take advantage of the extra cores / speed. Then you flash it with newer bios once you have put it together and booted. I would double make sure first though as its a long time since I used it.
