To begin with, the LGA2011 socket is powered by a 24-phase VRM that makes use of driver-MOSFETs, solid-chokes, and High-C POSCAP capacitors. The memory is powered by a 4-phase VRM. The board draws power, apart from the 24-pin ATX, from two 8-pin EPS connectors, and an optional 6-pin PCIe (to stabilize PCIe slot power delivery). We can see many accessories to this VRM, such as phase-loading LEDs, and consolidated voltage measurement points. We are particularly intrigued by the design of the heatsinks over the VRM and chipset. The one over the VRM looks like the barrels of a Gatling gun, while the one over the chipset looks like a small piece from an ammo belt. You will either love it or detest it.
Moving on to expansion, although the LGA2011 processor gives out 32 PCI-Express 3.0 lanes for graphics, the board is facing a lane budget deficit to wire its seven PCI-Experss x16 slots. Perhaps there is a PCI-Express bridge chip to give out additional lanes. The lane configuration is not known.
With storage connectivity, this board will give you a total of six SATA 6 Gb/s ports, from which two come from the X79 PCH, and four from additional controllers. Apart from the two 6 Gb/s ports, the X79 chipset also gives out four SATA 3 Gb/s ports. There are no eSATA ports. The board has a total of eight USB 3.0 ports, all driven by Renesas-made controllers, out of which four are on the rear panel, and four by internal headers. A nice touch here is that the front-panel headers are angled and laid beside the SATA port clusters.
The board features a high SNR (signal-noise-ratio) HD audio CODEC (probably ALC889), backed by Creative's X-Fi MB2 software that gives it even higher fidelity and more features. X-Fi MB2 software works on top of the HDA CODEC's native drivers, and so there is zero scope for any audio driver-related problems. The CODEC is wired to 8+2 channel analog outputs, optical and coaxial SPDIF outputs. There are two gigabit Ethernet connections, and surprisingly, both are driven by Intel-made gigabit Ethernet controllers. One of the two is driven by a compact 8257x series chip wired to the chipset's GbE lane, while the other is a full-fledged PCIe GbE controller. Both are backed by Intel
The MSI BigBang XPower II will be backed by a feature-rich UEFI firmware. Expect it to be among the most premium LGA2011 boards.
