Memory sometimes claims to support overclocking beyond 7200mhz on DDR5. Many believe CPUs can't handle more than around 5600mhz, and similar limits apply to DDR4 at 3200mhz. It seems these speeds are just theoretical claims rather than practical performance boosts. Despite this, people still purchase such high-speed RAM.

You can take advantage of these rates through (auto-)overclocking the memory using XMP. The 5600 MHz is the official limit set by AMD/Intel, while the other speed reflects what the RAM vendor claims their RAM can achieve (provided the CPU's controller supports it).

The maximum memory rate listed by Intel or AMD mainly serves RMA needs rather than being a strict hardware boundary. As long as your board or CPU allows memory overclocking—which it usually does—you can easily exceed that cap. For example, on a 13700K, you can run DDR5 8800 speeds; however, Intel doesn’t promise you’ll hit those rates at normal voltages. I’ve also seen that speeds above 7000MT/s are extremely difficult to maintain stably.
