Does anyone recall if (or which) bios was released that included a fix for a PCIe x1 problem (not sure if it was speed or voltage)?

I've just installed a new dual digital PCIe card on my DS3 board and it's having problems. It appears as if it isn't getting enough power tho I can't be sure.

I do know the card works on a different board (an asus) so the card isn't faulty so all I'm left with is my mobo causing problems.

Any suggestions?
