Thanks for your response. Actually the Zbook G4 I have has Quadro P5000 installed which is overkill for my workload. I was thinking to downgrade to a more reasonable P4000. Is the part number you mentioned is electrically or dimensionally different than that of the mxm 3.1b Quadro P4000 3.1b mentioned in my first post? If not then shouldn’t it work?
