Hi,

My motherboard is an ASUS P9X79 PRO. I'm trying to update my bios from current version 4502 to 4701.

Updating through flashback didn't work. I downloaded bios file v.4701, renamed it as P9X79PRO.CAP, turned the computer off, plugged the USB 2.0 FAT32 formatted, pressed the USB Bios flashback button for three seconds... It blinks six o seven times and then turns stable.

Updating the bios through the internet didn't work.

Updating the bios through a bios file tells me "image's model bios doesn't match with bios' rom installed".

Updating through Asus EZ Flash 2 utility tells me "security verification failed".

Any ideas?

Thank you very much!

 


Hi,

My CPU is an i7-4930K

I've made the same question to Asus, but I haven't got an answer yet.

Thank you for your help!

Best,
Manu

 


Since my bios version is 4502 and my motherboar's original CD has an P9X79PRO.CAP file I assume it's a CAP bios, but I really don't know. I haven't tried the cap converter, since I don't know.
