The importance of the EXPO profile:
BIOS settings :
It can’t be said often enough, but your memory kit parameters are not automatically set once you’ve installed it. If this is the case for your processor, it is not so for your memory kit and you will have to go through the BIOS! This is what we had to do with our Crosshair X870E HERO to get the BIOS to load the EXPO profile.
You can then configure it manually, choosing the right frequency, timings and voltage for your kit. For ease of use, we recommend that you enable EXPO mode (AMD) in ‘ AI Overclock Tuner ‘ so that it can be set automatically.
Without this, your performance will be impacted in all areas and you will end up with a kit that does not exceed the CL40 frequency of 4800 MHz. Performance will then be extremely limited. So we’re going to activate our EXPO profile directly in the BIOS. The proposed EXPO I is the 6000 MT/s profile. The other two profiles, EXPO and EXPO Tweaked, are very slightly different in terms of subtimings and sometimes perform slightly better. We invite you to try them out.
The ROG BIOSes, whether on the APEX or the Crosshair models, benefit from memory profiles. They provide a good basis for overclocking your memory kit. We’ll start by using them in our overclocking tests if they prove interesting, and we’ll explain all that later in the article. Our kit is now set up in the BIOS and will work with the manufacturer’s specifications.
As you can see from the screenshots above, once the EXPO profile has been activated, the settings are automatically detected. The frequency is set to 6000 MT/s, the 26-36-36-96 timings are activated and the voltage is increased to 1.40 volts.
