AMD Ryzen 3000 CPUs Reported To Suppport Up To DDR4-5000MHz Speeds

As AMD’s Computex 2019 keynote draws closer, it shouldn’t surprise anyone that new information about its upcoming Ryzen 3000 CPUs and Navi GPU will start to become more frequent. In the case of the latter, new details are now suggesting that the upcoming Ryzen series will allegedly be able to support DDR4 memory speeds as high as 5000MHz.

This specific bit of information was first posted by the Ukraine-based overclocker and PC enthusiast Yuri Bubliy (@1usmus. His actual name is written in Cyrillic). The tweet itself is simple, if not basic; he simply states that the maximum value for DDR4 RAM on the upcoming Ryzen 3000 series CPUs seems to be set at 5000MHz in UCLK mode.

For context, the UCLK refers to the frequency of the Unified Memory Controller (UMC). Typically, a first generation Ryzen 7 1700 with a cores clock of 3.0GHz with 2400MT/s DRAM will have a UCLK of 1200MHz. Therefore, a system running on a DDR4 memory kit with a 5000MHz frequency will technically have a UCLK running at 2500MHz, which is still blindingly fast.

I think it's time to start

The maximum value of the frequency of RAM Zen 2 generation is 5000 MHz mode UCLK == MEMCLK / 2.

According to Hot Hardware, one reason why AMD’s Ryzen 3000 series CPUs are reportedly able to support these speeds lies within its new 7nm Zen 2 CPU architecture. Specifically, the new memory controller for the new CPUs have its own I/O die.

To date, information surrounding AMD’s Ryzen 3000 CPUs have suggested that the new lineup will have several SKUs, with core counts ranging from 4-cores to 16-cores. Further, the new CPU will also come with new X570 motherboards, which are expected to introduce the next generation PCIe 4.0 slots.

Of course, it goes without saying that the Bubliy’s tweet isn’t official news from AMD, so take it with a liberal sprinkling of salt. At least, until AMD’s official announcement at Computex 2019.
