Can't get 2nd GPU working

[NaughtyPhoton]

Hello,

 

I just got a new Quadro k4200 from PNY, plopped it into my Rampage Black Edition in the 4th slot (PCIe x16) and I can not get Windows to recognize its' existence.  In the first PCIe slot I have a Titan Black EVGA superclocked which works fine.

 

I have switched the cards around, and put the Titan Black in the 4th slot and the Quadro in the 1st.  The Quadro was recognized and the Titan Black dissapeared.  So I know the Quadro works, just can't get the computer to see both of them.

 

Thank you for your help

No sir - they are all on

whoa thats weird =S 

ive never actually used a quadro but im pretty sure its just the same as any other GPU ?. 

maybe its a driver issue ?. or broken pcie ?

[NaughtyPhoton]

I'm a bit of a newb so don't rule out anything super obvious.

In the BIOS do I need to changfe anything when a new GPU is plugged in?

 

The way I have been checking if the comnputer sees the card is by opening GPU-z and seeing if I can select it.  Also, in the Device Manager it doesn't pop up.  Is there any softeware setting I'm missing to activate the PCIe slot?

I am no expert so maybe i am wrong.

 

Just a few questions. Do you want from these cards to work simultaniously or one at a time?

 

If simultaniously, thats imposible since you need SLI bridge and NVIDIA made it so only the SAME models can do that. That means 2x the same GPU. 

 thats what i read and heard also from Linuses videos but i might be wrong

 

If one at a time then i dont see the point in buying 2 GPUs

They will be running simultaneously, not on SLI.

 

The Quadro supports 10bit monitor for color grading - so I want to run monitor off that.  Leaving the Titan Black open for transcoding/processing.

 

Many applications support dual GPU including Nuke, Premiere, Vray Rendering, Resolve, etc.  I don't use SLI.

Alright i just wanted to check.

 

Have you checked if there is some problem with drivers for the second slot of the Mobo?

 

i am a total newbie i am jsut trying to help since i wanted to do something quite common with my another pc

Check the bios and ensure all the slots are on, especially the forth/third on some boards can be set differently when they run off a different chipset.
