It's too late, isn't it?  Can we move on?  The information I provided to s1lfy is sound.  If s1lfy has any more questions, I am sure that they will reply.

for those having problems with errors , you do NOT have to re install windows to boot into UEFI mode. All you have to do is convert the partition and validate it. Instructions are in  windows 10 MBR2GPT. 
I had a hard time trying to get to UEFI from lagacy mode and found these instructions that got got me thru.

Resizable bar worked at first for me when I did the update. I went in today to make sure it was enabled as I was going to try Gears5 which supports it.
Now it says "Please Check with your motheboard vendor"
GPU: EVGA 3080 FTW3 Ultra
Graphics VBIOS: 94.02.42.80.16
MOBO: ASUS z490 Prime-A running
MOBO BIOS: version 2004, CSM disabled, Boot method is UEFI. Windows was installed under 3mo ago. ResizeBar enabled and Resize Bar set to auto under PCI management. 
There must be an issue with how XOC is reading my motherboard. Can someone help?
 

OMG, get a life and move on.

I'm sure they will, but the guy literally said "I wish it didn't come to that" lol. Nobody is forcing you to defend your bad advice so feel free to move on. Manually deleting a recovery partition and then not knowing how to fix it is exactly why I said it was outside some people's technical abilities in the first place. Be careful who you get advice from folks, especially when they tell you to reinstall windows lmao.

But I didn't tell them that they had to reinstall Windows, did I? I said to try this conversion method, but it didn't work for me.

For everyone else: a recovery partition is irrelevant. You'd be cleaning the drive before converting to GPT so ideally you'd like to be on a bootable USB with the Macrium Rescue (or your software of choice).

Try it. If you don't have a recovery partition, the conversion process halts and gives you an error message about the missing recovery partition. I don't know why. It seems you don't either.

After hours of trying, I could not find one single guide on the internet that worked for how to recreate a recovery partition. I ended up needing to do a repair install to proceed. I am sorry that I am technically inept, but 1) get over it, and 2) one person's tale of their experience is not "bad advice". Tell your own tale however you want, but stop berating me about mine.

I have to wonder: why are you harassing me about saying that a Windows reinstall is the easiest solution to this problem, but not harassing EVGA for recommending the same thing?

What's done is done. We have a satisfying result. Move on. Let's not make this about you, or me.

Apologies if this has been asked already, is there an updated bios for the KP 1000w? Updating via X1 installs a 450w bios -- presumably by mistake.

Here is what you said: "In your case, with the way you installed Windows, you need to disable CSM and reinstall Windows."

I consider using a Windows setup disk or file to do a Windows install repair, a reinstall of Windows. That's what I did do. Repair install, re-doing the install, reinstalling. If you don't consider that a Windows reinstall, good for you. Move on.

Correct. What's done is done. s1lfy reinstalled when he didn't need to. Now I'm here to correct that mistake and prevent other people from taking your poor advice. Hell, I'll even go one step further and provide the idiot proof step-by-step.
 
I recommend using Macrium Reflect to backup JUST your windows partition. Not system reserved, not the recovery partition. (obviously you can and SHOULD have other full backups that include everything just in case, but for this procedure you just want that one partition). After doing so, boot to the Macrium Reflect Rescue Drive with whatever method you'd like. Open a command prompt (and ignore the colors below, not sure what the code tag is doing on these forums lol):
 

diskpart
list disk
select disk # <- select the drive number you want to convert
clean <- this will erase the disk selected above, make sure it is the drive you want to convert!
convert gpt
select part 1
delete part override <- this and "select part 1" might not do anything, and that's fine, just checking
create part EFI size=100
format fs=fat32 quick
assign letter=k
create part MSR size=16
exit
exit

 
Once that is done go back to Macrium and restore the windows partition to the unallocated space on the drive. Assign it a letter, let's say you did L (I picked K and L because theyre unlikely to be used already). Go back to command prompt:
 

bcdboot L:\Windows /s K: /f UEFI
exit

 
Before you leave, run the Macrium "Fix Windows Boot problems" just for good measure. Reboot to your bios and make sure they are set up correctly to boot to your drive in UEFI. 
 
Done. No windows reinstall. No data loss. No headaches trying to fix the stupid MBR2GPT tool if it fails to validate.
 
Feel free to DM me with any questions as I will probably refrain from checking in here again for my own sanity. If this helps you be sure to pay it forward and help someone else!

The update from Precision X1 doesn't work, it asks if I want to update and nothing happens. I have a 08G-P5-3755-KB (EVGA GeForce RTX 3070 XC3 ULTRA GAMING). 
 

• Windows 10 64 bits
• ROG Crosshair VII Hero (4301) (latest bios with CSM Disabled and Resize Enabled)
• EVGA GeForce RTX 3070 XC3 ULTRA GAMING (vBios 94.04.25.80.6A)
• Driver 465.89 installed

 
Where can I find the manual update?
 
EDIT: Used the BIOS from the post #80 and it worked but I saw in another post  that the max TDP is now 250W instead of the 270W. Waiting for a newer version. Probably this is why it didn't works from PX1.

My previous post explained this. EVGA is aware of it. Just hang tight and wait for a new one. They should have pulled the manual update thst had the wrong power limit

Is the update of the 3 bios of the KP working? I have read reports about problems and I still do not dare to update

Just updated my 3070 XC3 Ultra through p1x and rebar is enabled. Let's see if it was worth the effort.

This is also a great article on it - https://www.techpowerup.com/review/nvidia-pci-express-resizable-bar-performance-test/25.html
 
SHows that even in supported games - the difference is in a range of 1- 3 %



 
 

I got it to workbon my 3090 now! I found the original 3090 XC3 Hybrid vbios in a thread and flashed that. Then I reflashed the new vbios theough X1 with the 3070 unplugged and now it works. Resizable bar on both gpus!

Hey Jacob, @jacob I want to say thank you for your response in regard to the 3090 kp bios with bar support, which worked wonderfully, however I was wondering if you were able to provide or advise me on the 3090 kp 1000watts bar enabled bios?

Much appreciated

You'll likely need to contact Kingpin to get the unlocked, 1000W VBIOS with REBAR enabled - like you had to contact Kingpin for the non-REBAR enabled unlocked 1000W VBIOS.

Is the power limit at 270W? or 250W?

The slider goes to 113, other than that I don't know.

I did mine on day one using PX1 and the slider is now max 108... hoping that new bios comes sooner than later. 3070 XC3 Ultra

Hopefully @EVGA_JacobF can let us know if the Bios for the 3070 xc3 Ultra has been updated?

@thisISjoel -> TechPowerUp's GPU-Z would give you a better answer and I'd love to hear that your updated card has a high of 270W. Launch GPU-Z and go to the Advanced tab -> NVIDIA BIOS (in the drop down). There you will see the Power Limit in Watts.
 
Many are waiting on outright hearing from @EVGA_JacobF if the VBIOS for the EVGA GeForce RTX 3070 XC3 ULTRA (08G-P5-3755-KR) been updated or not.
