Laptop Ryzen 7 4800h RTX 2060 90W

Modded BIOS BIOS flashed successfully via programmer 341ch Above 4G On CSM off In GPU-Z ResizbleBar ON

The system constantly produces blue screen errors "video memory management internal"

Tried different versions of drivers, no luck.

If i disable Rebar via NvStrapsRebar.exe the errors disappear

Did you check the patches in the instructions in ReBarUEFI ?

Can you try a smaller BAR size ?

I can only guess the firmware (UEFI image) or vBIOS from the laptop manufacturer (Lenovo ?) does not like the new BAR size.

I followed the instructions, according to them, in my case patches are not needed. ReBar is detected in GPU-Z 8gb If the problem is in VBIOS, can I do anything about it?

I noticed you have a very old NVIDIA driver, can you also test with the latest one ?

And can you disable auto-setting for BAR size in NvStrapsReBar.exe, and then manually select a smaller BAR size like 1 GiB or 2 GiB ? Does it work then ?

I also encountered the same problem, I solved it by disabling the integrated graphics card, I think some modifications of the rebar conflict with the graphics card output mode of the laptop

Try installing the NVIDIA drivers using NVCleanstall, applying the “Disable NVIDIA HD audio device sleep timer” tweak.

By default, the NVIDIA drivers have a 4-second sleep timer for the audio controller. If the controller is not being used, the driver puts it to sleep. Many people have had audio issues because of that, so someone made a tweak to disable the timer. I have no idea why something like this impacts NvStrapsReBar causing BSODs (after all, the BSOD mentions the NVIDIA graphics driver, not the audio one), but I am pretty confident this tweak fixes it.
