Different BIOS - flash type and ROM size on Sapphire Pulse RX580 8GB

[bulgar73]

Hi,

I have 12 pcs of this card, Sapphire Pulse RX580 8GB Hynix, now I see that there are different FLASH type and SIZE of ROM, but the cards are the same. Can I flash this cards with one type of moded BIOS ?

Of course not. One is 0x80000 bytes, the other is 0x40000 bytes. What do you plan to do with the other half?

OK, but I do not understand why they are different, is it normal or what is this ?
Why they have different size ?

Just, modify the bios of them, apart from the others,

everything will be equal, but i recommend you dump and flash de bios apart

I don't know how is it with the newer cards but with the older Pitcairns or Tahitis you could flash lower ROMs and they would work no problem.

I remember that the original ROM or BIN was like 256kb but if you modified it with VBEtool it was like 128Kb and if flashed it still worked perfectly fine.

Those however had dual bios so it wasn't risky performing this.
