Can I run a PCI-E 2.0 card in a PCI-E 3.0 lane?

So my old graphics cards (x2) fried after a power surge.

I decided that this machine is only going to be used for audio production, and bought cheap cards. Only one card seems to be working though, now they claim to accept PCI-E 2.0, however I only have one PCI-E 2.0 lane on my motherboard (or so I am lead to believe). Surely the PCI-E 3.0 lanes would work wouldn't they?

The cards are Palit NVIDIA GeForce 210 1GB DDR3, and I'm running a Asus P8Z77-V mobo.

Thanks.

I've tried both cards in the PCI-E 3 slot and only the black lane is detecting a card.
In BIOS it's only detecting the black lane. The board itself is brand new (got it yesterday) and I've had two HD 5830's that are dead working in there.
