With no PCI cards installed, I was able to get my A10-7850k to:
RAM: 2200mhz (2133 * 1.04)
Running AMD Overdrive to auto overclock after doing this would immediately crash the system.
As soon as I put in my ASUS Xonar D2 and my Radeon 260x I was no longer able to overclock at all. Even setting the ram beyond 1333 (its rated at 2400) would cause the system to become unstable. I have since updated the BIOS and will try again.
