ASUS boards are usually made to last and works best. When I first look at the specifications, i was taken aback by the amount of features available on this board. The most eye catching is the support of DDR3-2133 and also SATA3. While most boards do not officially support these standards yet, ASUS is the first to embed these features into their design, offering a future proof solution to consumers.

For system stability, this board has an insane  32+3 phase power design, 32 phase for vcore and 3 phase for memory controller inside CPU. The board also incorporate a VIA VT2020, a 10 channel audio chip replacing the conventional Realtek on board. Although it has some top notch feature set, it only has 2 PCIe 2.0 full length slots. Thus, the spec sheet says that it supports quad crossfire and quad sli isn't very accurate (unless you are talking about two cards with 2 GPUs running in tandem). Other features like ExpressGate SSD and MemOK! are also interesting features that are unique to ASUS P7P55D Premium.

For overclockers, there is ASUS TurboV EVO. It pushes the system to the fastest, stable clock speeds with auto tuning. Turbo Key boosts performance with a simple touch while Turbo V offers additional advanced options. Alternatively, you can use the TurboV Remote. This hardware controller can help you overclock, activate turbo key and adjust EPU (for power savings) directly from a side controller external to the PC. Another thing that is special is the Dip switches on the side of the mainboard which enable/disable the user from accessing the higher ranges of voltages.

In our overclocking tests, we were able to get the system to boot into Windows 7 even at 21x200 (4.2GHz). This is done with just merely running the vcore to 1.42v, vtt=1.30v, vdimm=1.65v, CPU PLL = 1.9v. Again, we used a normal LGA775 heatsink on top of the CPU as we didn't have a LGA1156 heatsink.
