Can't use setup_var (offset out of range)

[OmarRod1314]

I'm trying to reduce the Max TOLUD of my Lenovo M72e (Ivy) BIOS so I can get 2 GB worth of PCIE address bar for my graphics card... Unfortunately, even with the identified 0x2D1 offset in my GUID file and the "1 GB" 0x3 value from there, I keep getting this error in the end of the sequence. No changes were made as I still had 256 MB of ReBar like before so... What's left to do?

Here's the file just in case, extracted with Universal-IFR-Extractor and UEFITool beforehand. The command I used is "setup_var 0x2D1 0x3" and the setup_var_3 version of it. Same results.
