MB doesn't detect 2nd graphic card in PCI_E4

caro · May 9, 2021

Hello,

I have been trying to use 2 NVIDIA graphic cards at the same time without success.
I have the following configuration
- MB: MSI X470 GAMING PLUS MAX
- Ryzen 3 3200g
- 2 EVGA GeForce RTX 3060 12GB
- 2 MSI Gaming trio GeForce RTX 3070

I am trying to at least connect 2 of these cards.
All of them work correctly in slot PCI_E1 but none of them work on PCI_E4. I have tried placing the 2x3070 (PCI_E1 and PCI_E4), the 2x3060 (PCI_E1 and PCI_E4), only the 3070 in Slot PCI_E4 and only the 3060 in slot PCI_E4. I thought it could be a slot problem so I changed the motherboard (to another one with the same reference) but still the card in PCI_E4 isn't detected by BIOS.
I upgraded the BIOS to latest version.
PCI_E1 Lanes Configuration only have x4+x4 and auto options.

Any idea of how to make this work?

Thanks in advance for any help.

Have you tried running your system with only one card in PCI_E4? If it works then it honestly sounds like MSI have done something dirty by not allowing you to run two Nvidia cards for non gaming purposes.

--- if you are trying to use them for gaming. The board doesnt support SLi. Thats why im pointing the finger at MSI doing something dodgy at the bios level to stop you plugging two Nvidia cards in.

Thanks for your reply.
I have tried running my system with only one card in PCI_E4 and it doesn't work.
A friend of mine has the same MB and running 4 cards - 2x3060, 1x3070 and another one I don't remember now. The only difference is that he has Ryzen 3 3100, so I don't think
The problem I am having is also happening to another friend. Same board, same processor.

What hard drives are you using, have you checked how many PCI-e lanes the APU has?
