problem titan x with quadro

[paride4331]

Hello, I have a hardware problem. I own 2 x titan x and 1 NVIDIA Quadro k620. the three cards have GPU maxwell. When I get on the Nvidia Quadro, Windows does not recognize the three video cards together and only recognizes as vga generic and loses the drivers of nvidia Titan x. After no longer able to install any driver. Nvidia states that on windows 10 cards with the same WDDM can safely be installed together. Can someone please help me? my motherboard is an asus x99-s. Thank you all.

Is the quadro for handing monitors and in the first pcie slot?

thanks for reply..
my pci slot are:

pci 1 > titan x
pci 2 > titan x
pci 5 > quadro

this is the setting in asus x99-s manual..

I do not know if that's my problem, because the cards do not work if I connect monitors to Titan x PCI slot 1.
I have two titan x installed now and I can connect monitors where I want to PCI 1 or 2 and everything works fine.
If I insert the card nVidia Quadro, and turn on the pc, immediately all tree cards become generic microsoft vga. when I try to reinstall the drivers, Windows gives me an error message.

I do not think the problem is the pci slot 1.. but I can try..

I had an old 580 fx quadro and I had same problem.. so I bought this k620 because I read this..

I think that the problem is Windows 10, but I could not install win7 on my harddrive M.2 ..

page 1-13 may give some important hints

1. Do you have a 28 or 40 pci lane cpu? 5820k or 5930k/5960k.
If 28 - use 1st, 2nd ,4th slots only for 8x speed.
if 40 - 1,3,5th for 16x (5th always as 8x), or 1,2,4 for 8x speed.

Try the following:

Put quadro into 1st slot, unplug (only remove cables but keep Xs in PCI slots physically on). Connect a monitor (also if you have two monitors) only to quadro. Run clean install of newest nvidia driver. Then connect power cables to only one X (slot #3 if 5930 or 5960) and see if the system recognizes it. If not run clean install of nvidia again. If not - place X into 2nd slot and try the same. If succeeded connect power cables to 2nd X (5th or 4 slot respectively).

Send feedback.

Thanks! I will try this weekend.
I have 40 lines (5930) ..
I have just to undestand what about sharing lines with M.2 hardrive.
M.2 shares lines with PCI x 5, so I Have

quadro pci 1 16x
titan x pci 3 16x
titan x pci 5 4x

this is not good..

or
quadro pci 1 8x
titan x pci 2 8x
titan x pci 4 8x

If M.2 (page 3-43) I'd go with 1,2,4 slots. Actually if you have 2 gpus at 16x and one at 8x you loose 16x performance - Octane will have to wait for the slowest card. For more than 2 gpus it's good to go with dual PLX chips motherboard, x99 e ws, asrock e ws , extreme 11. They give you 16x for 4 gpus.

I know.. for plx but I paid x99-s very chip to save money for 2x evga titan x hybrid.. (never exceed 45°... at 1440mhz ) it's a good motherboard.. I hope to solve with 1,2,4
I will feed you about.
thanks again

After hours of trying, finally the three video cards work together ..
Your advice worked , but ..
in windows 10 absolutely must install the drivers of video cards in safe mode .
I have only one problem : evga precision crashes and do not understand why, I tried to reinstall but nothing .

Try MSI AB - best soft IMO
