[HELP] Dell gtx675m vbios for Clevo gtx675m 4GB MXM3B

Hello, people
I got fan issue after I put Clevo gtx675m into my M17x R2.
I have asked around forums.
People said I need to flash my Clevo with Dell vbios to solve the fan problem.

I can only find this 2GB version of Dell 675m vbios.
But my Clevo is a 4GB version so I'm not sure what will happen if I flash my Clevo with that 2GB version Dell vbios.

I need help with Dell gtx675m vbios files.
Thanks
