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.
In this regard, AMD seems to have obtained good internal results with some 2933, 3200, and 3500 MT/s rated memory configurations, namely 16GB kits based on Samsung "B-die" memory chips. Potential kits that AMD has tested to pair well with Ryzen include Geil EVO X (GEX416GB3200C16DC [16-16-16-36 @ 1.35v]); G.Skill Trident Z (F4-3200C16D-16GTZR [16-18-18-36 @ 1.35v]) and the Corsair CMK16GX4M2B3200C16 (VERSION 5.39 [16-18-18-36 @ 1.35v]).
AMD also stressed incoming updates in regards to memory support of its AM4 platform, with updates being pushed to motherboard makers this May, which should enable support for memory at speeds "higher than the current DDR4-3200 limit without refclk adjustments." For reference, see below memory support tables according to memory speed, rank, and quantities supported by Ryzen processors.
