ASRock's socket LGA2011 motherboard lineup doesn't end with X79 Extreme7 as thought before, the company thinks there's scope for an even more loaded model that's literally bursting with connectivity and expansion features. Enter the X79 Extreme9. This board uses high-grade digital PWM circuitry to power the CPU. It draws power for the CPU VRM from two 8-pin EPS connectors. Unlike the X79 Extreme7, this board features eight DDR3 DIMM slots, two per memory channel. Expansion slots include five PCI-Express 3.0 x16, and a PCIe x1.

Since it completely ran out of room on the main PCB, ASRock put two important connectivity features on a separate (included) addon card, called the ASRock "Game Blaster". This card occupies the PCIe x1 slot, it packs a next-generation Creative SoundCore3D audio processor (more advanced than X-Fi), and a low-overhead/low-latency gigabit Ethernet connection. It's not exactly known if this connection is driven by a Killer 2100 or a more common PCIe GbE PHY backed by ASRock's proprietary packet prioritization software (XLAN).Moving on to storage connectivity, all six SATA ports from the PCH are wired as internal ones, with two SATA 6 Gb/s and four SATA 3 Gb/s from the PCH. There are six additional SATA 6 Gb/s and eSATA 6 Gb/s ports, all driven by Marvell-made controllers. There are four USB 3.0 controllers, which give out eight ports: four on the rear panel, and four via headers. Apart from the network connection on the addon card, there's another port on the board. Firewire and USB 2.0 ports make for the rest of it. The board will be driven by UEFI firmware. Expect it to be one of the more expensive LGA2011 offerings out there.
