See the gpu chip itself if it does not have warranty stickers.

Second is gpu memory speed? Bus and etc.

What RmemberThe5th said.

Also GPU-Z has a 'Look up' button on the first tab (Graphic card tab) which looks up the card based on Hardware Id and subvendor Id which links to a page about the card on techpowerup dot com.

I'm not sure if the IDs change flashing the BIOS. If they don't that would be another clue as what GPU and GDDR memory you're dealing with and what the card really is.
