Thanks again for your help TC. Installed the new bios & can now boot with CSM disabled

Governator
So I have a 3080 Ti FTW3 Ultra inbound, delivery on Fri the 27th and I've been plowing through all relevant threads and this is what I believe I need to do now, pics of my current BIOS setup below:
 
I've switched to my BIOS#3 on my Z490 Dark to ultimately test the 3080 Ti, currently have 1080 Ti installed..
 
1. Fast Boot is now off as of this writing in advance of installation:

 
2.My current CSM setting to accommodate the 1080 Ti when I installed my Z490 Dark last year, otherwise I did not get VGA, all 5x5 afterwards:

 
Now for installation of the 3080 Ti, speaking with those much wiser than I, and reading the relevant threads, I believe I have the following in the right order, please feel free to correct here, only thing I'm not 100% certain of is whether to install PX1 now or wait as per #4 above since I don't use it but instead use AB with my 1080 Ti (MSI GamingX 11G).  My sincere thanks to everyone who has contributed here in this thread (Courtesy of EVGA_JacobF), and most certainly to EVGATech_LeeM for his **MUST READ** thread: EVGA GeForce 30 Series HYBRID/XOC/Default BIOS Thread.
 
1. Start by uninstalling 1080 Ti drivers with DDU in "Safe Mode"
2. Disable CSM in BIOS, then shut down.
3. Install 3080 Ti card, boot into windows and install latest Nvidia drivers for it.
4. Install PX1 if not already and update cards BIOS if needed.
5. Rebooting to BIOS following step #4 above and enable Rebar support.

If you disable CSM now before you uninstall the 1080, can you boot into windows? Try that first. If windows is not installed as UEFI on GPT partitioned drive you could have problems.

right, well I've used MediaCreationTool21H1, then rufus, creating USB installation with GPT Partition scheme/UEFI (non CSM) for some time now, is this what we want then? thanks tc 👍

Yes.. that's exactly how I install lol You should be good. Per other reports here if you are using DP 1.4 you could run into problems with no display until VBIOS is updated on the new card. Other than that you should be good to go. There is a thread about that here...

funny, sounds good and actually we're using a 27" 4K Samsung but it's DP 1.2, however my new upcoming build will be with my Asus 43" XG438Q which is DP 1.4.

ok finally got my 3080 Ti FTW3 installed and updated, all 5x5. I know this probably was mentioned somewhere but my 3rd fan isn't running, the other 2 are fine, I'm still poking around PX1 as I write this.
 
 
 

Are you on the OC bios or normal..... normal at idle all fans are supposed to be off and OC all 3 should be running at 37%.

normal, running fans in manual mode...

update: all fans 5x5 now, just uninstalled PX1, reinstalled it and LED Sync and all is well.
update 2: running on OC bios currently

ok... sounded like manual in OC....on the 3080 FTW3 Ultra with the bios that  shipped with card you could manual adjust all 3 cards to 0% on the OC profile. One of the updates they decided to fix it so only one could be turned to 0%.Think that had to do with trying to combine the hybrid and normal bios. Do all the turn off if not in auto? If so EVGA will ignore all queries about it and say it's normal. Numerous posts in this thread about fans not turning off in manual mode.

Damn, how did you get 37° with 1950 clock?

I already did a vbios update while on the normal bios, now I'm on the the OC bios and PX1 is showing an update, is this correct?

also, can we hot switch or do we shut down first? personally I shut down to be safe...

so I'm getting this now,

"Resizable BAR cannot connect to server."

it's enabled fine, I updated earlier on Normal bios, however I forgot to install the Sync so I uninstalled & reinstalled PX1 and now see this.

showing Graphics VBIOS 94.02.71.00.B0

it connected finally after a few attempts, now vbios reads:

94.02.71.80.74

on 471.96 drivers btw

I'm confused. Should I do this? I'll only be playing at 1440 resolution max since that's the best my monitor can do.
 
I just got a 3070ti FTW last week,
 
Motherboard is a x570-P Prime
CPU is a Rysen 5 5600x.
 
Anyone know if the board is compatible?

Does anyone know the average performance gain of resizable bar? I am not sure I want to go through the hassle of a OS reinstall 3080 ti.
