I had 10 asus RX580 cards. And of course all the bioses where modified and flashed for known reason.

Cards where fine, not the best, not worst, just fans started to fail soon. So I RMAed them all one by one. At the beginning I received new cards in place but later I made mistake, flashed wrong bios and warranty was voided. So I know why. Recently I sent again 2 cards to same service center and this time i flashed exactly same BIOS file I had from one of the cards saved before. And I had warranty voided for both cards again.

So - do they really have a proof that bios was modified or are they playing me? Are they storing SN in bios or is there some kind of checksum that changes if BIOS has been rewritten? There is chance that I have been mistaken and I saved BIOS from card that I have been modified before OR... All cards came in 2 batches, maybe BIOS files where a little different for each batch.

But, to avoid that I have been just trolled and they can not actually proof bios reflash case - what are my chances? I have actually asked to service center to show me some kind of log file of some kind of software which they might use in case to check bios reflash event. Waiting for answer.

Let's put it this way, u are pretty much right about that they have some kind of SN in bios, but it is called a little bit different, it is called PPID, and Asus use it to detect any kinda of bios change on card or any kind of modification of bios in any way, when u are here, send me a message and i will explain u what can u do about it.
