I no longer can display my uefi in 1920x1080. It is displayed in 1024 low res mode. When I try to chnage my uefi to ultra fast boot, I get a D6 bios error on the led on my motherboard and the motherboard reboots almost instantly never even showing a screen. When I go back to changing it to fast boot, everything boots up fine and boots into windows no problem. I have installed win 10 pro correctly in guid gpt partition (disk management shows this in win 10 pro) but for some reason I can't enable ultra fast boot at all and the uefi is in freaking low resolution mode.

This used to work fine before I reinstalled win 10. I had 1920x1080 uefi and booted ultra fast boot no problem.

secure boot is enabled.
disabling fast boot brings up the CSM option in the bios which when I try to disable it, the same things happens, d6 error then reboot then back into bios with it auto enabled. Launch video OpROM for some reason will only stay on legacy only. I can't change it to uefi at all. It just reboots and switches back to legacy. pxe and storage oprom policy goes to uefi no problem. I have a Intel 600p nvme ssd which was installed in uefi mode (I think, now maybe not so since video oprom is legacy??) since I verified guid is the partition. But something isn't right. Is it my 1080gtx video card bios that isn't letting me enable ultra fast boot? Did I install windows 10 pro incorrect since maybe the video oprom policy was legacy? Did enabling secure boot really disable all of CSM?

I am stumped as to why the hell I can't enable ultra fast boot, low resolution uefi and freaking d6 error codes in all of this.

1080gtx evga ftw
600p intel nvme ssd
hdmi cable out to samsung 40 inch 1080p LED HDTV
650 watt evga p2 power supply.

Windows boots fine with fast boot enabled but I don't want that. I want full 1920x1080 uefi and to be able to ultra fast boot. Do you guys have any ideas or can point me in the right direction? Hope everyone has a Happy New year and thanks.

Edit: Well I fixed the uefi showing up in 1024 resolution. I just had to use the dvi port on my 1080gtx with a dvi to hdmi cable. Now the uefi is in 1920x1080. But the thing is, I can't for the life of me enable ultra fast boot. When I do, it goes right to a d6 error on the uefi led. Then goes back to fast boot. And the same stuff as posted above is true. Please help guys!

Quote The VGA could not be recognized. Please clear CMOS and try re-installing the VGA card. If the problem still exists, please try installing the VGA card in other slots or use other VGA cards.



Did you just add the 1080 FTW and then this occurs?

Also, I'd suggest updating to BIOS 3.40 as BIOSes at 7.00 and above are for the as of yet released Kabylake processors.

No, this worked before with the 1080gtx with no issue. The only thing I did was reinstall windows 10 and fully clear my cmos by powering off my system, pulling the power cable from the psu, pulling the cmos battery, jumpering pins 2 and 3 on the rtc jumper pins and then putting everything back.

Once that was done and I reinstalled win 10 pro, ultra fast boot does not work at all. Fast boot works fine. I am not sure what is going on.

My setup worked fine yesterday before my re-format/bios wipe. Version 7.00 and hell even 7.10 was working fine. I am not sure what went wrong.

This may seem stupid but go into the BIOS > Reset to UEFI Defaults then Save and Exit. Do this twice in succession.

And personally, I would fall back to 3.40. We've seen and replied to here many many issues with using the "Kabylake' 7.xx BIOSes with Skylake processors.
