AMD Ryzen 9000 “Zen 5” CPUs To Offer Up To 6400 MT/s 1:1 & 8000 MT/s 1:2 4-DIMM DDR5 Memory Support, Run Cooler & Lower Power By Default

AMD's next-generation Ryzen 9000 "Zen 5" Desktop CPUs will run cooler, consume lower power & feature enhanced DDR5 OC capabilities.

AMD's Ryzen 9000 "Zen 5" Desktop CPUs To Feature Great DDR5 Memory OC Support, Cooler & Lower Power Consumption Than Ryzen 7000 "Zen 4"

In today's topic covering the AMD Ryzen 9000 "Zen 5" Desktop CPUs, we will talk a bit about their DDR5 memory support & what kind of advantages they have to offer over the existing Ryzen 7000 series. The details come from our sources but we should point out that the data we obtained is based on engineering samples that are much closer to the QS designs. The final numbers will be similar if not better so let's start with the memory support and OC capabilities.

Sweet Spot DDR5-6000 Again But Upper Limit Enhanced To 6400 MT/s With Over 8000 MT/s OC Modules Easily Support

First of all, the integrated memory controller for the AMD Ryzen 9000 "Zen 5" CPUs is similar to the Ryzen 7000 "Zen 4" CPUs but comes with slight refinements. We have been told that the CPUs will be able to support DDR5-5600 by default and up to DDR5-6400 memory at a 1:1 fabric clock. The sweet spot is still going to be DDR5-6000 1:1 but on both X670 and X870, the upper limit will be set at 6400 MT/s.

As we already know, the AMD Ryzen Desktop CPUs feature three distinct clock speeds as a part of their internal memory structure, these include:

• Infinity Fabric Clock (FCLK): Governs how quickly CPU cores can communicate across CPU dies and with SOC controllers (e.g. PCIe, SATA, USB)
• Memory Controller (UCLK): Governs how quickly the memory controller can ingest/exgest commands from RAM.
• Memory Clock (MCLK): The frequency of your main system memory.

For those who want to push things higher, the X870E and X870 motherboards will offer a great OC design that is specifically geared towards memory overclocking with new and
