Is the system unable to start when XMP is activated?
XMP is a memory overclock setup that consistently surpasses the officially approved speeds of CPUs. On the 8700K, this is evident. Back then, Intel usually stuck to the same "approved" speed regardless of RAM upgrades or improvements in IMC. FTFY. Running four memory sticks is more challenging than two, and results will differ depending on the memory configuration. For identical frequencies, tighter timings tend to be less stable than looser ones. It appears the combination of four 3000MHz sticks was too demanding for that motherboard and CPU setup, especially without additional overclocking adjustments.
