Are the gpu locked into their pcie slots? Are they in the right slots - per mobo manual?

Is the SLI bridge attached properly? Are the power supply pwoer cables connected properly?

Have you set SLI with nVidia Control Panel?

Do two cards show up on Control Panel, Device Manager, Display Adapters?

Do both cards have the latest drivers installed?

I'm having the same problem my board.

Yes, the cards seeded correctly.
Both cards get power. (1200W supply)
The board does not detect the 2nd card - but does when each card is found independently. Tried each card in the 1st and 3rd slot - both work when not accompanied by the other. The 2nd card does not POST in the BIOS.
Yes, the bridge is found and properly attached.
Drivers are installed with the Nvidia Experience.

I think you need to start your own thread. I'm waiting to hear back from the OP.

You need to post your build - per forum guideline eg crappy psu or motherboard can cause these sort of problems.

Could be.

I don't think he's coming back. Maybe he went through checking stuff and found something not connected well.

If he comes back and he's still got problems, he'll need to post his build.
