I am trying to do a "native" UEFI boot but I am having issue with the CSM option, in every shutdown, the setting gets reset but other settings stay intact. When I restart Windows 10, the setting stays sometimes. If I do not have Auto Source Option On in my monitor (searches for active input between HDMI, DVI and Displayport) , CSM gets reset too. I'm using a certified Displayport cable.

Same for me on my Elite. If you find a solution let me know.

edit: I'm guessing it's has something to do with the GPU.
UEFI booting requires the video device to support the GOP video protocol used with UEFI booting.
But both of our cards are relatively new so that shouldn't be a problem, right?

Specs:

CPU: Ryzen 3700x
Motherboard: Gigabyte x570 Aorus Elite
OS: Windows 10 1903
SSD (Main): Samsung 970 Pro (NVME M2)
GPU: Gigabyte 1070
PSU: Seasonic Focus Plus 850
Monitor: LG 34WK650 (DisplayPort)

Yeah, depends on the video card, some of the video cards have vbios switches that usually have a legacy and uefi (with gop) or legacy+uefi. I use GPU-z to see if the vbios supports Uefi. In the menu it will show a check mark.

Edit/Added:
The boot/main hard drive also has to be formatted in GPT for Windows OS for uefi support.

Seems fine to me.
Still, if I disable CSM in the bios it reverts back to enabled after a reboot (without booting into windows).
Any other ideas?

Well I tested today with HDMI and it works now. I'm guessing it's the motherboard's Uefi(bios) Displayport implementation/handshake. The HDMI in my monitor only supports up to 120hz instead of 144hz using Displayport. @samesame, try with a HDMI cable and turn off both monitor and pc and turn everything back on and see if you can get csm disabled working.

I found a link from nvidia's forums with a user having similar issue and the user had a Gigabyte AM4 motherboard but I'm not sure if that user was able to fix it.

I'm not sure how widespread is this issue and if other users have noticed this issue.

@GBT-MatthewH
Hopefully you can help us with this issue?

I also have a a TV connected to the HDMI.
I'll try to unplug the monitor (DP) and only leave the TV connected and if that doesn't do it I'll try the monitor via HDMI to see if this has any effect on CSM.

On a side note, I hate that HDMI has priority over DP on boot. I always have to turn on the TV to mess with bios settings.
edit: I did some searching and apparently disabling CMS on other boards solves this annoyance. Another reason to get this sorted!

An update on CSM.
As soon as I connect anything to the DisplayPort the CSM gets enabled.
You can even hear that the board resets twice, with the fans going on max.
If I leave only the HDMI connected (either the TV or the monitor) CSM stays disabled and boots normally (laggy UEFI included of course). I've even tried a few different DP cables to no effect.

 

[samesame]

So did anyone try F4N on the Elite?
Any changes regarding CSM or is it still broken?
I'll probably just wait for the new agesa update regardless.

Good to know, thanks!

Add outputting UEFI to DisplayPort first (when HDMI connected) and/so that I can disable CSM and it's golden for me.

Well I just solved the CMS problems I was having.
Was watching a monitor review from Wendell where he was talking about an nvidia firmware update.

Never heard of this before. Couldn't hurt to try, right?

Lo and behold I can now disable the CSM and the UEFI shows up on the monitor first now (Monitor on DP, TV on HDMI).

This was the last thing that bugged me on this setup.
Ok, the long boot times and fans going to max at boot bug me a little but I'm running my rig 24/7 so that's a non issue.

Hope this helps someone.

Had to update to 10A to get RDR2 working. Working fine so far.

Also have it set on silent but it doesn't help since it goes off due to high temps. I previously had a 2 slot gpu that just barely covered the chipset fan and had no issues while the current gpu is a 3 slot and it fully covers it. The whole pc is almost silent and then this thing goes off...

You can drop > 10°C by removing the subpar thermal pad and use a good paste on the chipset heatsink if you haven't already and also remove the god damn sticker that's over it xD
I also just swapped the GPU and it's completely covering the fan, the chipset temp never goes above 55°C. I don't have any pcie4 devices except the GPU though so that might be a factor.

What kind of a case do you have? I just did an experiment. Opened my side panel for 1h and the temps dropped by almost 10°C.

The case i'm using is an NZXT h500 - poor airflow all around. Seems like i'd be better of replacing it. My gpu's also been idling at 57-58°C
