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?

if this is anything like the elitebook 8570W misadventure i had when trying to make a GTX 965M work, you have to choose the correct VBios otherwise the machine wont POST. It will fire up but no display output to screen. what Vbios does your Fermi have on it.  You might be seeing a misalignment of DP_A, B C etc not being assigned to the display.  Try the TechPowerup forum for other versions of Vbios.  I know on my machine it only ever came with 3 card options from factory, despite what HP techs said no Whitelist "apparently" existed.  Ive seen INF mods needed for some cards too
