uh, that's unfortunate
Sorry you ran into complications.
I have 12 of these cards. Some of them bought used and the rest in several batches from amazon... all 12 were running 113-2E3470U.X51 bios.
Did the card not boot from the alternate bios after flicking the bios switch?
I edited OP with a warning for the bios version.
Yes - it did not started from "non-silent" mode
Now - having the warning it is OK. Mine BIOS was completely different than yours.
Good luck!
