To Get the Best, Start with Xtreme Design

Golden Ratio of 16:9 for Widescreen Movies and Games ASUS True 12+2 Phase Power Design
The P7P55D-E PRO is built based on the groundbreaking 12+2 phase VRM design. The 12+2 phase power design, 12-phase for vCore and extra 2-phase for Memory controller inside CPU, can provide the highest power efficiency, and hence generates less heat to effectively enhance the overclocking capability. With the high quality power components such as low RDS (on) MOSFETs, Ferrite core chokes with lower hysteresis loss and 100% Japan-made high quality conductive polymer capacitors, ASUS 12+2 phase VRM design also ensure longer component life and minimum power loss.

T.Probe: Leading Active Cooling Technology
Working together with the 12+2 power design is the T.Probe microchip. It reduces specific hotspots on the critical power components by detecting and balancing power phase loads and temperatures real-time. With optimal power phase functions, components run cooler and extend system lifespan.

With T.Probe, efficiency of the 12+2 phase power design is essentially boosted to that of a 16 phase power system.*

TRUE USB 3.0 and SATA 6 Gb/s Performance

Stay connected even longer Unique PCIe x4 Bridge Chip for Ultra Performance:
At ASUS, we understand that bottlenecks and performance barriers is just not acceptable when you want a system that can keep up with you.

Typically by using a plain solution of directly connecting USB 3.0 and SATA 3 controllers to the P55 chipset, only 250MB/s can be achieved. To get the full 500MB/s, ASUS utilizes an unique bridge chip solution that utilizes an additional PCIe x4 pathway to remove the bottleneck. With the TRUE USB 3.0 and SATA 6 Gb/s performance, you can truely benefit from the ultra high transfer speeds from the next generation storage solutions.

With solutions from other brands, you will NOT be able to run a CrossFireX/SLI setup if you enable the USB 3.0 or SATA 3 models, whereas there are no such limitations on the ASUS solution.

Don't settle for less. With TRUE USB 3.0 and SATA 6 Gb/s, your ASUS P55 motherboard can transfer movies, music, and backup files up to 50% faster - without sarificing graphics bandwidth or modifying bios settings.

Quick and Direct Overclocking Methods

Golden Ratio of 16:9 for Widescreen Movies and Games Whether you are a first time overclocker or trying to break the next world record, you will appreciate the comprehensive yet simple to use overclocking tools that comes with the P7P55D-E PRO.

Packed with features such as Auto Tuning and hardware controlled TurboV EVO processor, this motherboard allows you to just sit back and let it do all the hardwork. Auto Tuning overclocks the processor automatically by intelligently detecting current system configuration and determining the overclocking margins. After trying different settings, TurboV EVO will conduct stability tests and fine-tunes the settings until the system is rock solid and achieving its optimal performance, all within minutes.

If you are an enthusiasts that enjoy the process of overclocking the old fashion way, you can do so now easier with the hardware TurboV EVO chip that directly communicates with the CPU for OC settings and stability tests.
