"... there is no upside for preventing users from using four sticks of RAM."
I beg to differ. Upsides:
* Reduced motherboard cost.
* More space available for CPU cooler and other components.
Another "pro":
* Wide range of video connectors for use with an APU.
(How many of the other tested motherboards have HDMI, DVI and VGA ports?)
A comparison between those motherboards using a 2200G and internal graphics only, paired with a set of cheap RAM (instead of 1700X, high end RAM and discrete graphics), would put this motherboard in its correct element.
That said I'd rather spend a few bucks more to get the B350 chipset with full overclocking capabilities...
