How do you tell whether memory is Hynix or Elpida. Looking at Ausdauersportler post 20,272 in gpu upgrade thread chart it looks like they can have either. Each with different VBios. How do you tell the difference? Are the chips marked? Also if Hynix how do you tell AFR from BFR. Looks like 4 different ROM versions for this card in GRML Flash USB files.

Take a photo of the RAM chip.
Google the marks on it or post it here.
You will figure it out yourself when comparing with other cards' photos.
 
Ok finally got back to this the memory is Samsung. So what v bios do I use? Hynix AFR, BFR or Elpida?
