This is my mb model

GIGABYTE Z370P D3 (rev. 1.0) LGA 1151 (300 Series) Intel Z370 HDMI SATA 6Gb/s USB 3.1 ATX Intel Motherboard

The one sli I got doesn't work. It's to long. It's a two slot. So ordered a one slot. If that don't work. Anyone know which one I need? Thank you

If your system is for gaming, don't bother with an SLI setup. The specifications page lists your board as having support for crossfire only. Which means that you don't have 8 lanes per PCIe x16 slot when two cards are populated.

So I assume this second GPU won't work for my rig? Would I need another mb? For it to work?
