" rel="nofollow - Hi,

Is the following setup possible?

- SLI setup (PCIe1 and PCIe 5) - both cards 16x

- A network card in PCIe4 - 4x or 8x (it doesn't matter)

A 44 lane CPU is already present...

Thanks.

Dear UdoG,

X299 OC Formula's PCIe slot will run at x16/x0/x0/x16/x8 or x8/x8/x8/x8/x8 (PCIE1/PCIE3/PCIE4/PCIE5/PCIE7) when 44 lanes CPU installed.

If you want to use two x16 slots and one x4, we suggest connecting the VGA card at PCIE1 and PCIE5(x16), and connect the LAN card at PCIE7(x8).
