Hello! I’m fairly inexperienced with over clocking despite having been a pc gamer for many years. I just finished a new build and it is my first time using the EXPO set up as opposed to just setting my Dram at the advertised speed. I’ve attached a photo where you can see the bios is notifying me that EXPO 1 will run at higher speeds than EXPO 2, why is this? From the "research" I had initially performed it seemed EXPO 2 was the more “demanding” option and that EXPO 1 should only be used if 2 is too unstable. Why does mine seem to be the other way around?

Any tips appreciated, thanks!
