Hello.
On September 2023 I bought two RX 560 4gb from Aliexpress, branded XFX, and I tried them both either on a Broadwell socket 1150 CPU PC (one at a time, since it has only one pcie x16 slot), either on an HP Omen i5-8600k computer, especially in this last one, for a crossfire config.
On the first rig they worked normally, booting, testing them, etc, but I didn't used them there for long, just for test.
On the second computer, the Omen, they had just a weird behavior at boot POST: they showed an artifacted bi-color pattern, then the pc booted normally and everything worked correctly as always.
After some weeks that I didn't boot the Omen PC, they stopped working: no image from HDMI or DVI-D outputs. Since I don't have a displayport monitor at hand, I couldn't try it too. I tried them both even on the Broadwell computer, no avail.
I saved both BIOSes and it is exactly this one for both cards (already existing in the bios database): https://www.techpowerup.com/vgabios/193096/193096
I suspect a bad modified BIOS and I want to try to flash the correct bios, trying to save them (I already tried to heat one up with a heat gun, to no avail), so can anyone tell me which BIOS should I try?
Btw: I found an official RX560 BIOS from HP, can I try it as well? It is this one: https://www.techpowerup.com/vgabios/211027/hp-rx560-4096-180322
I'll attach a picture of one of the card (they're identical) and of the back plate sticker. Both cards have Hynix memory chips.
Thank you in advance.
