2 video cards

[bobn]

I have an older desktop (Intel DZ77BH-55K, [email protected], 32GB ram and Nvidia GeForce GTX 650) with W10 Pro v 22H2. I just purchased a Nvidia GeForce RTX 3060 for dual monitors. I installed the new device and wouldn't boot to windows. I put the old GTX650 back in PCI Bus 1 and new RTX 3060 in PCI Bus 2. Restarted and got it working. However I don’t want 2 video cards and 3 monitors. I only want the RTX 3060. How do I remove the old GTX 650 and leave the new card in PCI Bus 2 because it’s longer.

Just so we are on the same page here. Those video cards will only work in the blue PCIE slots, the black one are pci slots and not compatible. The 3060 most likely needs a power connector from the power supply and it will not boot without it.

 

[bobn]

Yes both in the blue slots and yes the 8pin power supply is connected. Oddly both work

Does the 3060 in the top slot interfere with something? The card should work just fine in the second slot all by itself, it will be only at half speed though since that slot is at 8x instead of 16x.

 

[bobn]

Yes in the top slot it hits the chipset which is why i moved it in the second slot

 

[johnb35]

Thats weird that the chipset is too high. If the pc won't boot with the 3060 in the second slot then go into the bios and see if there is a setting for initial video output. Probably won't be but a suggestion. Not sure what else to do here.

 

[bobn]

I'm going to put it the first slot ...got nothing to lose at this point. I set the bios for general which was default. Thanks for all your input!

 

[johnb35]

Your posts are confusing. Thought you said it wouldn't fit in the first slot due to the chipset?

 

[bobn]

Sorry for the misunderstanding...it fits but rests slightly on top on the chipset

The Intel MB displays on startup but goes blank soon afterwards if that helps.

Either it's a bad card or possibly a driver issue. Uninstall driver for the 650, don't let windows reinstall it. Shut system down. Put 3060 in top slot. Boot windows amd see what happens. Are you sure the 3060 is inserted all the way?

 

[bobn]

The card is good because it works in the second slot only if the 650 is in the first slot. I'm sure it's a driver issue. The 3060 is inserted all the way.
When you say Uninstall driver for the 650, you mean from the Device Manager, correct? I'll try that and see. I'll do this next week . I'm heading out shortly for the weekend and will advise you what happens.

Any difference between using the CSM compatibility and full UEFI mode?

Tried all that you said and still the same.. Put the old card back in.....Either the card is no good or my motherboard isn't compatible. Either way I'm returning it back to Amazon. I appreciate all your help!
