Leaked slide explains how memory overclocking occurs on systems with AMD Ryzen 5000 processors

As evidenced by the slide leak, AMD now recommends using faster memory modules that can operate at a higher frequency with its Ryzen 5000 series processors.

The published slide describes memory overclocking on systems with new generation AMD Ryzen processors. And the slide explains the differences between the three internal frequencies associated with the operation of RAM:

  • Infinity Fabric Clock (fclk): Determines how fast the processor cores can communicate between individual CPU dies and with the chipset controller (e.g. PCIe, SATA, USB).
  • Memory Controller Clock (uclk): Determines how fast the memory controller can receive / retrieve commands from RAM.
  • Memory Clock (mclk): The frequency of the main system memory.

The Zen3 architecture provides a 1: 1: 1 ratio for each mentioned clock speed. And now the user can tune the frequencies to provide the best performance for the memory subsystem and the entire system. Slide also explains that DDR4-4000 memory is just as suitable for Zen3 processors (Ryzen 5000) as DDR4-3800 was suitable for Zen2 processors (Ryzen 3000 series).

The architecture-based AMD Ryzen 5000 processors were officially announced last week. Their actual sales will begin on November 5th.
