Clevo W860/870CU Nvidia Quadro Fermi GPU upgrade

[Driftking60]

Hello,

I have a W870CU where I believe the GTX 460M is starting to die (it needs to be underclocked or else the system will hard crash). I decided to take a gamble on a Dell NVIDIA Quadro 3000M as it was cheap and also Fermi. I installed it into my machine (it was quick and easy, no need to modify/change the heatsink), but when trying to power it back on, the screen is all black with the laptop beeping continuously.

 

Has anybody who has had success with upgrading one of these chime and let me know what GPU’s work and if this laptop has a vBIOS whitelist?
