I came home and my desktop was off, when i started it up it would boot to the mobo splash screen but no further. I When I originally built it I had this same issue and I had to use another GPU I had laying around and install windows and run the force-enable-gen3 to get past the splash screen with the 670. I've tried running force-enable-gen3 again, I've set RMPcieLinkSpeed to 4 in the registry, but it still will only boot to my splash screen with my 670 installed. With a spare Radeon HD 6900 it boots and runs just fine.

Mobo: GIGABYTE GA-X79-UD3
CPU: Intel I-7 3930K
GPU: GIGABYTE GTX 670
Windows 10
 
It's an issue with the card itself. And editing the registry won't make the machine boot past the splash screen, this is a hardware issue not a software issue.

Have you tried inserting the 6900 and set bios to defaults, shut system down, take out 6900 and insert 670?
 
Yes I've set the BIOS to default and tried the 670. It only boots to the splash screen. If it's not a software issue why did the enable-gen3 fix my problem when I first built this system a few years ago?
 
I don't see why it would not run even with 2.0. Don't know but Nvidia says, (Therefore we’ve decided to only support and guarantee PCI Express 2.0 bus speeds on X79/SNB-E). I would just completely rest the bios and try again.
 
If the gen3 fix is bios related then it may have. But actually changing a registry setting within windows won't change how it boots.
 
I've reset the BIOS numerous times. I've had these cards in and out at least a dozen times in the last few days seeing if anything I did worked. I'm curious if there is another method to enable gen3 support in windows 10 since that is what worked back in windows 7 to allow me to boot.
 
Which motherboard revision do you have? 1.0 or 1.1?

Also what bios version do you have?

If you have revision 1.0 then bios update F20 may help.
 
Did you install the force-enable-gen3 exe. If so uninstall it and start over trying without it and updating to the F20 bios if that's the rev you have with the 6900.

Revision 1.0 and F11. I downloaded the F20 update from gigabyte and went to run it in Q-Flash but it told me that my flash utility was outdated. Unless I'm doing something wrong.
 
Did you unzip the file first? You can also try using the @bios windows utility to update it.
 
Yes I did. I heard that @bios crashes in windows 10. And when I tried to update @BIOS I get the error "This Driver can't release to failure".

My USB drive has autoexec.bat, Efiflash.exe and X79UD3.F20 on it.
 
Ok, did you put all 3 files on your flash drive or just the actual bios update file?

You should just have 1 file labeled x79ud3.f20. Then try the update using qflash again.
 
Had just the 1 file. Selected it in Q-Flash and get this.

Do I need to update to F16 first?
 
You might have to. It's not uncommon that you have to update in stages for some boards.
 
Had to make a bootable drive with efiflash and do it that way. Scariest moments of my life. But it's updated to F20 now. Now to try the 670.
