P9X79 firmware includes several automatic and manual overclocking options in addition to Asus OC Tuner, which is designed to automatically find the company's idea of an optimized overclock based on incremental clock increases and stability tests. We’re a little cautious with core voltage settings, though, and prefer to set this manually.

We didn’t quite reach 4.7 GHz on the P9X79, but small 0.1 MHz BCLK increments allowed us to set 4672 MHz using the same 47x CPU multiplier.
The P9X79 plays on our love of simplified menus by placing key voltage controls on the main Ai Tweaker menu. Per-channel DRAM reference voltage levels might be perceived as over-the-top, however, since only the most persistent tweakers use these.

Choosing “Ultra High” CPU Load-line Calibration from the DIGI+ Power Control submenu allows us to retain a CPU core voltage very close to our targeted 1.35 V under heavy processor loads.

Disabling EIST within the CPU Performance Settings submenu let us lock in a constant 47x CPU multiplier, exceeding non-Turbo Boost ratios even though the menu shows Turbo Mode disabled.
The P9X79’s DRAM Timing Control submenu adds slew rate to the familiar primary, secondary, and tertiary timings.

Since the boards all have vastly superior profit margins, your statement is misleading. Why is everyone too afraid to reveal the truth about motherboard pricing?
A comparison of the time between the power button being pressed and the installed bootloader starting would be very interesting to me. I was thinking it might be easiest to measure this by having no OS on the boot media and measuring the time to the "please insert boot media" message, but I'm sure you can think of other ways of doing it.
I'm also informed that on some boards the boot time varies dramatically dependent on whether any Overclocking is enabled, as compared to the stock settings - that would also be worth knowing.
not anymore, asrock is no longer affiliated with Asus and is owned by Pegatron Corp.
But I'm wondering why AMD continues the ATI brand on the ASrock motherboard? Seems odd. They had everyone replace the CCC as soon as they rebranded and here we are looking at the ATI logo on the ASrock board.
Also, even though there is so little difference when comparing boards using the same architecture, why no BF3 in the gaming section of the review? I thought this was one of the games mentioned in the 2012 goals for Tom's when reviewing gaming performance?
I settled on the ASRock Extreme4-m. I did have to wait for a new BIOS chip to arrive in order to make use of it though. They overnighted one to me last week and I got my system up and running over the weekend. So far so good. I've been quite happy with it now that it's working. I can't say that I've tried the overclocking features.
With the ASRock Extreme4-m the memory slots and CPU 8-pin power connectors are very close to the radiator. I went with the Intel liquid cooler for my build. It's a 120mm fan and radiator. I placed these in a Silverstone FT03 as exhaust from the top of the case. It's important to pick out RAM that doesn't have any crazy fins or spikes on it. I went with some Kingston HyperX DDR3 1600 4x4GB that were on the official support list. There is a 4 to 5 mm gap between the RAM and radiator. it is plenty of room for the 8-pin wires to clear without touching the RAM or radiator. It's tight, but it works. I originally was going to buy GSkill RAM that was $20 cheaper, but there's no way the big red fins on those sticks would have fit.
I don't blame them for skipping BF3. Since the most recent video drivers I've been having all sorts of issues with BF3. It's the only game on my machine to display a "Something went wrong" error and crash the entire system. I'd imagine it's hard to benchmark such an unstable game. My Extreme4-m, i7 3820, and Radeon 7950 system has no trouble with Just Cause 2, GTA IV, Crysis, and others, but BF3 has this remarkable capability to come up with the most ridiculous of error messages and strange behavior. That game still has issues.
