Easy to configure, many bios options, easy over clocking
Maybe a little pricey, but you get what you pay for.
So far I've found this to be an excellent motherboard. Lots of excellent features. If you're considering this motherboard then check out the many excellent reviews at various web sites.

My latest build consisted of:

Intel i5-750 CPU
Lancool PC-K62 Case
Corsair HX1000w Power Supply
Corsair H50 CPU Cooler
Corsair XMS 8gb i5 Memory Kit (4x2gb)

XFX Radeon HD 5770 Video Card (soon to be x2)
Sound Blaster Audigy 2

loaded with features, impressive layout, easy to use
first board shipped was DOA
I purchased this motherboard as part of my first system build. This motherboard is very difficult for me to review.

The first board shipped to me arrived DOA. This caused some grief in troubleshooting my system to find out what component was at fault.

On the other hand even while troubleshooting I fell in love with this board. Even though the first one was defective I absolutely love this motherboard. It's loaded with features with plenty of room for expansion.

If it wasn't for the first board I'd easily give this 5 stars. Even with that I still highly recommend it.

huge overclockability
easy to use BIOS
Power/Reset buttons right on the board
BIOS reset button on back panel
remote to set favorite O/C profiles while running OS.
Nothing, other than the underdeveloped system software.
This is by far the best Motherboard I have ever used.
Mobo: Asus P7P55D DELUXE
CPU: Intel(R) Core(TM) i5 CPU 750 u 2.67GHz (OC 4.045GHz)
RAM: Patriot Extreme Performance Viper 4GB 2X2GB PC3-12800 DDR3-1600 CL9-9-9-24
H/D: Patriot Warp V2 32GB SSD
Cooler: Noctua NH-U12P SE2Heatpipe Cooler W/ 2XNH-P12 120MM Fans

I purchase Asus exclusivly, and this board is top drawer.

Originally, I purchased the G.SKILL F3-12800CL7D-4GBRH Ripjaws PC3-12800 RAM, but after setting up the machine (and unable to boot to BIOS) I found out that this RAM was not in the QVL (Qualified Vendors List)therefore changing to the Patriot. Also went from a OCZ GameXStream 850W ATX12V 24PIN SLI Ready, to an Antec Truepower Quattro 1000W Power Supply SLI Ready (for my dual XFX GTX275s).

This machine is exactly what I was looking for my upgrade.

At first (with the original BIOS) I could only get the machine to O/C to 3.6GHz. I updated the BIOS to version 0711 and it unlocked some features that were not available with the original. My first attempt put me a 3.7GHz, shortly later I got it up to over 4GHz on Air! I had to disable the C-State in BIOS in order to do this. With C-State on I hold 3.7GHz steady and have not attempted to increase it yet.

At 4GHz+ my temps and wattages were a little high, (52 degrees Celcius, 109W) but I've run AMD CPUs at 64+ 24/7 for months.. so no big deal.


There are still some tweaks I haven't played with yet.. however, what I have used so far is fantastic.

Comment: In the wake of Intel's Lynnfield processor release you'll certainly find a lot of P55 chipset based reviews all over the web. For Guru3D this will not be any different; we have multiple P55 reviews lined up as well. It's hot technology, and the latest mainstream and enthusiast gear. What

Comment: "I came away from the P7P55D Deluxe with mixed feelings. For some reason, the board just did not seem that "special" to me. I know this is not an ROG board, but it is the "Deluxe" model of its series and it just did not seem too deluxe."
