P8Z77-V unable to enable Above 4G about rebaruefi HOT 15 CLOSED

my mod bios (seems all ok) Asus p8z77-v based on 2104 + NVME + above 4g + rebar + patch rebar https://drive.google.com/file/d/1iZCs8gfIdqxcELeb-RKBOa-EzGWiN4W6/view?usp=sharing

Sadly for me yours when rebar is set to 16GB turns on red light for PCI-E.

Closing issue since for me everything is solved (except missing cursor when I enable rebar, but that isn't big deal for me.)

Are you sure pad file is done correctly ?

Also IFR method works for most people but you can try using AMIBCP to enable hidden menu if u want to

from rebaruefi.

I checked the PAD files where I put the rebar module, they seem to be the same, I will try the AMIBCP method but have to delid my i7 3770k, when I can use it I will update.

ASUS almost always has pad file issue are you sure

"Enabling hidden 4G decoding" method do not change anything. CPU-Z says "disable"
amibcp_v4-55-0070 method also do not show anything in MB bios

Some part fixed. You need change to user in only ONE place.
And you will get new menu in the bios where you can activate 4g

Thank you, I was able to patch it, and now it's working perfectly!

@xCuri0, you were right, even though there was no obvious difference, something happened to those PAD files so I had to use the MMTool method.
Without patches, in case there was a POST interruption, like the CPU fan spinning way too slowly, the system would be soft-bricked.
Now it works flawlessly. I used the patch.txt and IvyUSB3.txt files.

If allowed, I can share the resulting BIOS.

Do it.
Have you made the following changes yet? DSDT Patching ?
Or it is fine without?

I looked into it and it seems to me that it doesn't need to be patched, I played Forza 5 without a problem so far.
Here is how it looks like:

                Else
                {
                    CreateQWordField (BUF0, \_SB.PCI0._Y0F._LEN, M2LN)  // _LEN: Length
                    CreateQWordField (BUF0, \_SB.PCI0._Y0F._MIN, M2MN)  // _MIN: Minimum Base Address
                    CreateQWordField (BUF0, \_SB.PCI0._Y0F._MAX, M2MX)  // _MAX: Maximum Base Address
                    M2MX = 0x0000000FFFFFFFFF
                    If ((TUUD >= 0x1000))
                    {
                        M2MN = (TUUD << 0x14)
                    }
                    Else
                    {
                        M2MN = 0x0000000100000000
                    }

                    M2LN = ((M2MX - M2MN) + One)
                }

Hello, thanks for sharing. I flash it, enable above 4G, and set ReBarUEFI.exe = 8.
but GPU-Z displayed resizebar disabled. could you tell me how to enable it? thanks.

Z77VB.CAP.zip
based on P8Z77-V-ASUS-2104, modifications :

1. uefipatched (bar size limit removal, usb3 whitelist)
2. add nvme support
3. above 4g decoding = on by default and can not set off ( i didnt unhide the option)
4. video oprom policy = uefi only by default
5. add rebardxe with unlimited BAR size, regardless of value set by rebarstate

feedback from @Kur0ex , works without issue.
