ASRock enables Crossfire on AMD770 Motherboard
 

ASRock A770CrossFire AMD 770+SB700 mainboard. As you are probably aware, the AMD 770 chipset was released earlier this year together with 790X and 790FX. So, why is it that ASRock interested in making a AMD 770 solution ? If you look at this page on AMD website, you would have noticed that the AMD 770 chipset is just a scaled down version of the 790X chipset. The AMD 770 does not support GPU-Plex, Quad PCIe blocks and CrossFireX.

Although not officially supported, ASRock has found a way to enable CrossFire X and XpressRoute on the AMD 770 chipset. They found GOLD in it. That is why ASRock comes out with this board using the entry level AMD 770+SB700 chipsets that can do whatever the expensive boards promises.
