AMD’s third-generation Ryzen (3000 series) processor will overcome the memory limitations faced by the old Ryzen chip. In Zen 2 AMD has separated the memory controller from the CPU core and presented it in a separate “I/O” chip.
According to the source, overclocking capabilities are significantly improved in the third generation Ryzen processors. This is indicated by the memory frequency support found in the Zen 2 BIOS up to DDR4-5000. The DRAM clock frequency is still related to the Infinity Fabric (IF) bus clock frequency. This means that at the DDR4-5000 memory frequency, the Infinity Fabric bus would also have to work at a clock frequency of 2500 MHz. Since this speed is not available for IF, the developers decided to add a 1/2 divider mode for the internal bus. In this mode, the IF operates at half the clock frequency of DRAM (in the case of DDR4-5000, at a frequency of 1250 MHz).

In addition, the new platform has SoC overclocking mode and the ability to control the voltage VDDG.
This may be an additional advantage of motherboards based on the AMD X570 chipset since their BIOS will include not only parameters for a higher memory clock frequency but also a divider mode.
