A88XM-A

I think I screwed up. I've been out of the loop way too long. I ordered an Asus A88XM-A FM2+ mobo and was silly enough to think that the A4-860K FM+ would work in it. I haven't received either yet, but just discovered that it probably won't work. Checking Asus's site revealed that the 860K isn't supported for that mobo. Would I be better off not even trying? If so, which should I exchange, mobo or CPU?

The A4-860K, isn't that the Athlon X4 860k? It's on the list 3rd from the bottom of the page. https://www.asus.com/us/Motherboards/A88XMA/HelpDesk_CPU/
If it doesn't work it'll be a bios update that's needed.

I swear I looked up and down that list and didn't see it there. Looks like I'm good to go then.
