CPU-Z – DDR5 with an Intel Core i9 13900K, with XMP enabled
Let’s start with CPU-Z. It’s an essential tool for checking the current configuration of the system. In most cases, you should enable XMP, and that’s it. Otherwise, the memory will run at 4800 MHz, slowing down your rig. Sometimes, XMP won’t work, so you might have to set the timings manually. With the Asus ROG Maximus Z790 Hero, all it took was to change one setting (XMP with DDR5-600), save the BIOS, and reboot.
We haven’t encountered any problems when booting the Intel system. It started with the memory running at 6400 MHz without any issues.
DDR5 does indicate a double data rate, so you don’t have to worry about the displayed memory clock, as the effective RAM frequency is 6400 MHz.
