The model version of DDR5 memory refers to the voltage range of the power management integrated circuit (PMIC) of the modules. This is because in DDR5, voltage control has been moved to the memory modules.

Two example part numbers with the model version in bold are CMK32GX5M2B5200C38 and CMK32GX5M2X5200C38.

The meaning of the above model versions are:

  • B: Overclocked PMIC supports up to 1.435V on VCC/VDD
  • X: Extreme overclocked PMIC supports up to 1.9V on VCC/VDD
