Re-Size BAR Option, Unsupported Hardware

Specs listed in signature.
I have option to enable resizable bar in latest bios, but my hardware seems to be not listed to support it. Will this work if I enable it?

Resizable Bar is only available if you have a 3xxx & 5xxx series CPU and also then requires a 3xxx series gfx card. The GFX card needs to also have it's vBIOS updated to support it

Yes, but I still have option to enable it in msi bios. That is what I am cofused about.
