And what is the bios version on the one I have ordered? Is it compatible?
Or wil I only know when it is delivered?
Yes, you can find out, when you get your hands on it.http://www.asrock.com/support/index.asp?cat=FindBIOS
You could also ask your retailer, if this mobo would support a fx cpu out of the box.
Your mobo would most likely be a 2013 version, so I believe you won't need a BIOS update.
