With the Extreme6 motherboard, I was amazed to see that my CPU was stable at the same 4.8GHz frequency, but at a much lower voltage (1.265V on the Extreme4 and 1.255V on the Extreme6, values set in the UEFI interface):

Here is also the 4.8GHz validation:

With the latest version of AIDA64, we can extract more information regarding the motherboard, the CPU IMC and the P67 chipset:

The ASRock Windows system customization utility was reworked and now contains features like OC DNA, IES (which were offered as separate applications in the past). In the first tab, we can find the Hardware Monitor, where we can see the current clock speeds, temperatures, fan speeds and voltages in real time:

The Fan Control tab allows us to customize the speed of the installed fans:

The Overclocking tab permits us to modify the clock frequencies, CPU ratio and voltages on the fly:

In the OC DNA tab, we can see listed the motherboard model, its currently installed UEFI version and UEFI build date; here we can also save or load current profiles, without entering the UEFI interface:

Finally, in the IES tab, if we have Power Saving enabled in UEFI, we can see this option turned on and the application also shows us how many phases are used in real time:

The ASRock XFast USB is another interesting application that comes with the motherboard and permits to boost the read/write transfer speeds of any USB storage device:

To see if this application has some impact to the transfer speeds, I have inserted a USB 2.0 flash drive and did some read and write tests:

Xfast USB Read Normal

Xfast USB Read Turbo

Xfast USB Write Normal

Xfast USB Write Turbo

SmartView is another application on the ASRock CD, that acts like a portal with multiple functionalities:

The Extreme6 motherboard does also come with the Instant Boot application, which boosts considerably the computer boot time:

On the CD we can also find a trial version of the Creative X-FI MB, CyberLink DVD Suite and a standalone registered THX TruStudio PRO™ application:
