G73JW upgrade to GTX660M 2GB GDRR5

[MuR3]

Hello.

I know this could be quite old , but I'm trying to install a GTX660M 2GB GDRR5 in my ASUS ROG G73JW , hope to be able to make it work.

The reference chart is this:

80.07.39.00.0F

I got to ride with the heatsink and modified G73JH laptop starts but gives an error of VBIOS , must understand that flash the VBIOS new graphics card .

Has anyone tried to put a GTX660M 2GB in this notebook ?

Can this be done ?

I read all the post 2012 on changing GTX660M GTX460M to 1GB, but I wonder if you can put a 2GB and if there is modified for her VBIOS .

Greetings and thanks.
