Having problem updating to the F13 BIOS for Gigabyte GTX 670 (GV-N670OC-2GD)

[poohbear]

hello, I'm trying to update my Gigabyte GTX 670 (GV-N670OC-2GD) to the latest F13 bios, but when i try to do it with the Gigabyte's VGA utility "@ Bios" it tells me the Bios attempt failed and i'm using the wrong bios?  I''m certain its not the wrong bios, i updated before to the F4 bios (my card was bought in July 2012, it came with the F2 bios), so why isn't it updating this time?   I'm using the latest download of the VGA @ Bios utility (5.1) that i got from the Gigabyte linke.  What am i doing wrong?  How do i update to the F13 bios correctly? 

Here is the link to the Bios page of my card:

Single digit bios update to single digit bios so you should be updating to F5. The double digit bios are for a slightly different flavour of GV-N670OC-2GD.

Any reason you are trying to flash your bios?
