The ASRock X79 Extreme11 is probably the most complete motherboard released so far for the LGA2011 platform. It includes seven PCI Express 3.0 x16 slots, eight additional SAS/SATA-600 ports, eight USB 3.0 ports, and a high-end audio controller. The most important feature of this motherboard is the presence of two PLX PEX8747 chips, which allow you to install up to four PCI Express 3.0 video cards truly working at x16 speed. Let’s check it out.

In Figure 1, you see the ASRock X79 Extreme11 motherboard. It uses the CEB form factor (12 x 10.5 inches or 305 x 267 mm), which is a little deeper than standard ATX motherboards (12 x 9.6 inches or 305 x 244 mm). Therefore, you need to make sure that your computer case is compatible with the CEB form factor.
