Hello,

I have to upgrade my vBios to UEFI on my HD7990 graphic card. (HD7990-6G-GDDR5)

There is two vBios (Master ans Slave), it 's a dual GPU.

Can you help me for this operation ?

I contacted Sapphire, they have no upgrade.


I disabled UEFI boot for logicals disks, i have no more UEFI options.

Only Asus have a tool but only for Asus Card and mainboard.

There is no vBios available on https://www.techpowerup.com/vgabios

My GPU-z informations :



Anyone know the issue ?

Thanks.
