AMD 6950 Red VGA LED

[Ottonomous]

Had it since 2011 and it never worked but I suspect a corrupted BIOS(?)

Placed in the second slot it produced this ????

I tried
- Individual RAM input and memtest
- Researching multiple cases of P67 ASUS boards having QVL issues (a lot with the 6950 for some reason)
- websites with botched BIOS where it was restored in aftermarket boards (my only hope and I am trying it now)

Not tried
- Weird UEFI BIOS trick where changing PCI Express from gen 2 to 1 seemed to get AMD cards working for lots of people (power delivery? boards had some issues that were resolved previously, included the upper PCI Slot shutting down spontaneously and with PCI U3->X1 returning)

Any hope for it?

flashed multiple 6950 Sapphire BIOSes to no avail

Did you try switching the BIOS switch?

Non-reference, I am assuming they're non-flashable without permabricking, ergo any attempts would originally be futile? I received it with the 'corrupted BIOS' so I thought it couldn't be any worse if I tried.

I know this is an expression of frustration and I apologize, but is there any plausible scenario where I could get it fixed, or at least diagnosed? Would the GPU-Z reading be indicative of anything problematic like permanently corrupted BIOS, one subcomponent being damaged like a capacitator or at the very least, dirtied PCIE risers or at least, PCI-E incompatibility on the motherboard (some people mysteriously got it to run at PCI-E Gen1/2 instead of 3)?
