Question

New graphics card on "old" mobo

Apr 27, 2017 1:11PM PDT

Hey everyone, I bought a new graphics card ( radeon rx480) and tried to build it into my "old" computer with a Gigabyte x79 ud3 mobo.however the mobo doesn't recognize the card. I tried to reset cmos which did not help. A bios update was not possible so far as i could not use the q-flash option for some reason. The pc still works fine with the old card. Any suggestions? Any help is much appreciated.

Who says the card is good?

Have to test on another PC. There is some bad information going about there a card is UEFI only. So far I only found these to be UEFI and other, compatible, not "only."

Anyhow, there's also the old didn't plug it in all the way issue and some cards require a power connection. Check that out now.

As to the BIOS, ask the maker how to update. It's important in cases like this.

Unless you test, you can't know.

And without the BIOS update you can't know if it's that.

Get the BIOS out of the way and if you go nowhere, consider exchanging it for the other big maker. I find a few, very few machines that I swap ATI for Nvidia or back work after I change horses. It's rare and something I see about once a year over a thousand machines.

Look around in your bios for a 'legacy boot' option.

In your spare time work on getting the latest bios.

It might be a fix for uefi and that new card.
