A quick view of the board finds an excellent layout that is designed for those who value expansion or multi-GPU capabilities. MSI utilizes the VIA VT6315N chipset for IEEE 1394a support, Realtek ALC 889a 8-channel HD audio codec, and dual Realtek 8112DL Gigabit LAN controllers. Why manufacturers continue to ignore the native Intel Gigabit LAN support in the P55 is beyond us.

The board also features 13 USB 2.0 ports (six headers/ seven ports on the I/O panel), an eSATA/USB combo power port, and support for up to 16GB of dual-channel DDR3 memory with standard BIOS support up to DDR3-2133. MSI includes power-on/reset/clear CMOS switches and a Debug LED panel for the open bench crowd.

Right below the DIMM slots is MSI's new V-Kit option. The four pin switch header lets the user override the BIOS limits for VCore, VTT, DDR, and PCH values, which are already more than high enough to void warranties or damage your CPU. However, for those needing that extra voltage, these switches could come into play for extreme overclocks. A really nice feature for the OC crowd is the voltage check block that lets users measure actual voltages for VCore, VTT, DDR, and PCH values without have to run various leads around the board for a Digital Multimeter.

The P55-GD80 features six (black) SATA 3Gb/s ports provided by the P55 chipset that feature RAID 0, 1, 5, and 10 support along with Intel’s new version 9 Matrix Storage technology. The dark blue SATA connectors are powered by the JMicron JMB322 3Gb/s SATA chipset that feature RAID 0 and 1 support. The eSATA 3Gb/s port on the I/O panel and IDE port are provided by the JMicron JMB363 chipset.

The board features two PCIe 2.0 x1 slots, two PCI slots, and three PCIe 2.0 x16 slots (x16/x4 or x8/x8/x4). The x4 PCIe slot (third one on the right) is provided by the P55 chipset and is not designed for optimal graphic’s performance. The layout of the PCI/PCIe slots is very good and allows for a single PCIe x1, PCIe x4, and PCI slot when running SLI or CrossFire.

The CPU area is basically uncluttered and a push/pull CPU fan/heatsink design like the Vigor Monsoon III will not interfere with low-rise (heatsinks) memory in the first DIMM slot. The back of the board is clean and we expect various air/water coolers that require a back plate to work fine. We were hoping to see Socket 775 mounting holes on this board as an option.  MSI is utilizing a 8-phase power system (DrMOS technology) that has allowed easy 240+ Bclk rates in early testing. For the more extreme overlcocking crowd, the capacitors around the CPU socket could present problems, but this is a trend we have noticed with all P55 boards to date.

The rear panel features the standard PS/2 mouse and keyboard ports, optical/coaxial S/PDIF out ports, seven USB 2.0 ports, dual Gigabit LAN ports, IEEE 1394a port, audio panel, and a handy eSATA/USB powered combo port.

The Easy Button 2 package is on this particular board.  Instead of using the traditional buttons, MSI designed an electromagnetic touch design for the power-on/reset/Green Power (active phase switching tech) functions. Also in this area is the clear CMOS, OC Genie (intelligent auto overclock system and more), Debug panel, and the return of the Base Clock buttons that let you adjust Bclk values in real time on the board.

MSI would greatly appreciate your opinions on this board.
