"Throughout this review we pointed out several minor issues we uncovered with the ASRock X79 Extreme6/GB mainboard. However, in conclusion I would like to once again stress its indisputable advantages. This mainboard comes with sufficient accessories bundle including a universal panel that provides two additional USB 3.0 ports. The PCB layout is overall good; it offers eight memory DIMM slots, two processor fan connectors supporting rotation speed adjustment, additional SATA and USB 3.0 controllers, buttons and POST-code indicator. The digital processor voltage regulator circuitry is built with high-quality components including tantalum capacitors. It works as 12+2 and supports dynamic adjustment of the number of active phases depending on the processor load even during overclocking. Three graphics card slots allow building AMD Quad CrossFireX, 3-Way CrossFireX and CrossFireX, as well as NVIDIA Quad SLI, 3-Way SLI and SLI configurations. The mainboard has pretty convenient BIOS that offers everything necessary for system configuring and fine-tuning. Everything we have just said can also be applied to a similar ASRock X79 Extreme6 mainboard, but the “SB” model comes with additional expansion card featuring a second Broadcom network controller and Creative Sound Core3D Audio processor. This is a unique distinguishing feature of the ASRock X79 Extreme6/GB mainboard, because there are not that many other products that come bundled with a Creative sound solution."
