Asus ROG Crosshair IV Formula

Asus TurboV & Turbo Key

Turbo V vs Turbo Key...

As you may or may not be aware, there are two different Automatic Overclocking options on the Crosshair IV Formula motherboard. Asus TurboV is the brand's software utility, which deals with both manual and automated overclocking within your Operating System.

Turbo Key

Asus Turbo Key is probably the fastest way to overclock your processor. The only prerequisite knowledge required is how to press a button, as the next time you boot into your operating system you'll find yourself with an overclocked CPU. While the final result is far from optimal, it has certainly done reasonably well by overclocking our Phenom II X4 965 Processor to 3685MHz; an 8% improvement. Unfortunately this 8% improvement in CPU frequency has also resulted in a 10% decrease in Memory Frequency and a Voltage bump of 0.05V.

Not a brilliant overclock but in most tasks should yield a small performance boost. Given the ease of use and time involved, one can't complain.


Asus TurboV is a software utility that offers Manual and Automatic Overclocking functionality. As a manual tweaking utility it allows you to manipulate most of the vital parameters you'd find in BIOS. The tool doesn't offer quite as much flexibility as AMD Overdrive however TurboV also allows the user to adjust the CPU Multiplier of individual CPU cores.

The automated overclocking tool is probably the most interesting aspect of the application. Like Turbo Key, no prerequisite overclocking knowledge is required; the Auto Tab shows a self explanatory diagram, indicating the key phases of a CPU Overclock (Frequency Increase, Voltage manipulation, Stability Testing etc)

Once you commence the Automatic Tuner, the TurboV window maximises to occupy the entire screen. This prevents the user from running other tasks at the same time but also provides vital information about the status of the overclock.

After several cycles of the procedure, the system locked up and restarted. Once the operating system had reloaded, Asus TurboV automatically continues where it left off. After a further ten minutes, the tuner confirmed a final frequency of 3838MHz and a marginally reduced memory frequency of DDR3-1504. As far as automated overclocks are concerned, this is rather impressive.

In short, those who are less keen to learn about CPU Overclocking may find either of these utilities very useful. As always your mileage may vary and any overclock should be followed by an extensive run of CPU Stability tests such as OCCT and Prime95.

Let's move on to manual overclocking shall we?

Mmmm pretty damn sexy mobo, any news on the Extreme? (£ / Release dates?)Quote

Wow, this is cheap for a ROG and that is, if it does turn out to launch around this price.

I suspect the Extreme would be more, am guessing around ~£200?Quote

Yeah i was thinking around the £225 mark, got a few months till my course starts so more than enough time for some more boards running the new chipset to come out and compare the performance/overclocks, i just hope these keep ahead of them as "Well it is the best board i can buy for it" is more than a good enough excuse to buy such a good looking mobo.Quote

Compared to intel offerings with similar features, £167 seems like good value to me. Compared to other AMD boards it's a little pricey, but the performance looks hard to beat.Quote

Its a very nice board, Im a sucker for good looks it does kinda help its a doddle to use aswell.Quote
