The importance of the XMP profile:
Setup within the BIOS:
We can’t say it enough, but the settings of your memory kit are not set automatically after installing it. If this is the case for your processor, it is not the case for your memory kit and a passage through the BIOS will be mandatory! You will be able to configure it manually, by choosing the right frequency, the timings as well as the voltage corresponding to your kit. For more convenience, we advise you to activate the XMP (Intel) or DOCP (AMD) mode in “AI Overclock Tuner” in order to set it up automatically.
Without this, your performance will be impacted in all areas and you will end up with a kit that does not exceed 4800 MHz in CL40. So we will activate our XMP profile directly in the BIOS. Many of you have asked us about the difference between the XMP I and XMP II profiles. The XMP I profile loads the default profile, the XMP II profile sometimes optimizes some subtimings more.
The Asus BIOS, both on the APEX and on the Crosshair models, benefit from memory profiles. They are good bases to overclock your memory kit. We will first use them in our overclocking tests. Our kit is now set up in the BIOS and will work with the manufacturer’s specifications.
As you have seen in the above captures, once the XMP profile is activated, the settings are automatically detected. The frequency goes up to 6400 MT/s, the timings are activated and the voltage goes up to 1.40 volt on the VDD and VDDQ.
