This question already has an answer here:

I am considering buying the motherboard listed below. The specs say it has a PCI-E 2.0 x16 slot. There are PCI-E 2.0 x16 video cards. But there are 3.0 x16 graphics cards available but there don't seem to be motherboards that list 3.0 x16 in their specs.

What in the specs of a motherboard would indicate that a video card 3.0 x16 would be compatible? Maybe the specs of the motherboard should in fact list 3.0 x16 if the slot is available, I'm just not finding them?

GIGABYTE GA-970A-D3 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard

Thanks, Charlie

I believe that you will only find PCIe 3.0x16 listed on Intel based motherboards of the newer variety.

Here is a sample Intel board from the same manufacturer:

Gigabyte board with PCIe 3.0x16 Model GA-Z77X-UD3H

Partial spec list up to the PCIe expansion slots:


Supported CPU CPU Socket TypeLGA 1155CPU TypeCore i7 / i5 / i3 (LGA1155)

Chipsets North BridgeIntel Z77

Number of Memory Slots4×240pin Memory StandardDDR3 2666(OC)/1600/1333/1066Maximum Memory Supported32GBChannel SupportedDual Channel

Expansion Slots

PCI Express 3.0 x16 =2 (x16, x8)

PCI Express 2.0 x16 = 1 @x4

PCI Express x1 = 3

PCIe 3.0 are backward compatible to PCIe 2.0x16

Thanks much. Yes, my search was limited to AMD boards. – Charlie Wilson May 5 '13 at 1:22
