Someone has done a bit of research on the firmware of the FTW3 cards, apparently cards effected with the red LED of death have a signal from the mcu relating to improper voltage at the pcie connection.  When the card sees this it prevents it from turning on.  Hard to tell if the card messed the mobo causing this to happen by pulling more than spec voltage, or if something in the card itself fried causing the controller to see incorrect voltage.

    If you bought an FTW3 Ultra, I highly recommend the $30 5-year warranty or $60 10-year warranty. It's stupid cheap considering the failure rate and cost of replacement.

    10700k @ 5.4ghz, 3090 K|NGP|N, 4x8 @4300 16-16-16-36, EVGA 1200 P2, MSI Z490 Unify, 5 radiators, 2 pumps. Heavily modified Evolv ATX

    Thanks for the post as it explains why my card probably died. More importantly it helps decide what my replacement is going to be for my 3090FTW Hybrid.

    Its getting to the point where it seems like EVGA is never going to acknowledge this issue, there is no chance they don't know what it is by now. Really unfortunate.

    I guess it's on a need to know basis and we don't need to know.

    I posted a indepth write up on it here and how to fix it flashing a modifed version with all the checks bypassed, Since my mates card failed like that which has no warranty and wouldnt boot on his computer but ran on mine.

    Got approval from one of the mods to post it but it seems to have been deleted.
    They left the MCU flashing tool post in the PX1 thread tho lol.

    But really unless you have hardware modded your card and have no warranty your best to go though EVGA and try you luck getting a replacement card instead of bypassing saftey features.

    If it can be fixed with a bios flash that disable checks wouldn't that suggest its a software issue. I think most people who have had the red light of death have tried on other people's computers to no avail
