AMD Shares Details on Ryzen DDR4 Memory Support and Upcoming AM4 Updates
In a blog post titled "Tips for Building a Better AMD Ryzen System", AMD has shed some light on the current memory support quirks with their Ryzen CPUs. First interesting detail: Ryzen processors do not offer memory dividers for DDR4-3000 or DDR4-3400. As such, AMD recommends that users looking to use higher memory speeds with their Ryzen processors instead look towards 3200 or 3500 MT/s. Due to Ryzen's preferences when it comes to memory, AMD also recommends that users pay particular attention to motherboard vendor's memory QVL lists for speeds greater than DDR4-2667.
Remember RAM importance on Ryzen processors' performance, which is given newfound importance in alleviating possible bottlenecks related to AMD's Data Fabric, the interconnect technology being used to communicate between different CCX's in AMD's 8-core Ryzen 7 and upcoming 6-core Ryzen 5 processors. Higher data rate of your memory subsystem should better help Ryzen's inter-core communication, and thus allow for higher performance in multiple scenarios, more so than with any other current CPU architecture.
