I guess you need to wait for the L5/I or L5p/I with the new 6xxx or 12xxx CPUs to get those.

 

Those already been released and here is the VBIOS from a L5 whit the I5 12500H straight from lenovo themselves:

https://download.lenovo.com/consumer/mobiles/legion5pro_16iah7h.exe

The issue is that after successfully flashing that VBIOS is still limited to 130W as is shown in the screenshot so that VBIOS is either not compatible for some weird reason or Lenovo limited the GPU power in other way.

Maybe the ACPI tables or the EC is limiting the power?

 

try it. may help you。

Thanks but it didn't work.

When i reboot the screen is black and the fans are at max speed so after many trial and error i come to the conclusion that only the VBIOS whit device id 10DE 2560 will work and the VBIOS you posted is 10DE 2520.

 

I have experimented with the 140W bios on L5p as well. I got the same end result that you did and could not get the gpu above 130W.

Unfortunately, the 2022 AMD models are using a different bios to the 2021 models it is JUCN43WW instead of GKCNXXWW so I suspect that it is the EC that is controlling the power delivery to the GPU

Not sure if you'll see this, but there's a program called Lenovo Legion Toolkit that provides a custom power mode which unlocks the EC and allows a flashed vBIOS to actually run at a higher wattage.

Here is another VBIOS but as TyTystick said, you can download Legion Toolkit and enable custom mode

Then set cTGP to 10 and dynamic boost to 0 and it should boost to 140w when enabled

Thanks to everybody that suggested ways to increase the power limit here but i just give up with all this firmware nonsense and just shunt modded the laptop replacing the 1206 R005 resistors with R004 resistors so now the RTX 3060 can pull up to 160W and obviously the GPU VRM is not happy about that so soldering some additional heat pipes was needed.

This of course not going to fix the stuttering mess that some games like The Last of Us is going to be with just 6GB of VRAM but maybe i can figure out how to upgrade that to 12GB like this Russian guy did on this video
