Will the Asus FM2+ Motherboards support a PCIe 3.0 Card while running a Fm2 Processor?

So Asus states that thier fm2+ motherborads (ex A88XM-A) Do not support PCIe 3.0 if a fm2 chip is running in the broad. Can anyone explain to me why this is and if there is a way around it?

Thanks.

pcie 3.0 are backwards compatible with 2.0 slots, you wont see any difference as far as performance even if you had a 3.0 slot on that motherboard.

most amd boards do not have pcie 3.0 slots on them besides like 2 of the high end am3+ boards

Well the motherboard does have a pci 3.0 slot, just it states that a *Only FM2+ Processors can support pcie 3.0 and im running on a FM2 not a +.

So I was just confused to if it would ignore a 3.0 card because my board can support 3.0 just not sure with my current processor according to asus.

ahhh does your board have any pcie 2.0 x16 slots on it? the 3.0 slot should run at 2.0 speeds though if its not supported by the processor

It has one PCIe 2.0/3.0 16x Slot. So the even if its a PCIe 3.0 card it will just run at 2.0 on my board and my processor will support it fine?

yes ^^ it is fine to put a PCIe 3.0 Card in a 2.0 slot, PCIe 3.0 is backwards compatible.
