When using the dmidecode command, we can see the speed of RAM:
Speed: 2933 MHz and
Configured Clock Speed: 2666 MHz Which one is the currently running speed? Why are there two speed items?

In dmidecode’s output for memory, “Speed” is the highest speed supported by the DIMM, as determined by JEDEC SPD information. “Configured Clock Speed” is the speed at which it is currently running (as set up during boot).
The latter may be higher than the former, e.g. with DIMMs providing higher speeds described by Intel XMP profiles.
