AMD recently announced its Ryzen 7000 (Raphael) processors. Robert Hallock, AMD’s technical director of marketing, has revealed additional information about the best RAM for the new Zen 4 chips.
Hallock commented on AMD’s official Discord channel (via). Bionic_squash (opens in new tab)) Memory overclocking for Ryzen 7000 processors is slightly different than previous Ryzen 5000 (Vermeer) chips. First of all, Hallock confirms that maintaining a 1:1:1 ratio on the Infinity Fabric Clock (FCLK), Unified Memory Controller Clock (UCLK), and Memory Clock (MEMCLK) is no longer essential Did. Instead, we advise users to leave FCLK set to Auto and overclock their DDR5 memory modules and memory controllers at a 1:1 ratio. As a result, the optimal configuration is Auto:1:1.
Zen 4 parts have a default FCLK of 1,733 MHz and support DDR5-5200 memory by default. Hallock believes DDR5-6000 will be the sweet spot for Zen 4 based on cost, stability, performance, availability and ease of use. In contrast, Zen 3’s sweet spot is at DDR4-3600 (1,800 MHz FCLK), with DDR4-4000 (2,000 MHz FCLK) being the golden standard. Nonetheless, Hallock said that in some scenarios, exceeding 2,000 MHz FCLK can improve performance. However, it is not a priority for most users. Zen 4 will take AMD’s word for it until he can run RAM benchmarks.
Current DDR5-6000 16GB (2x8GB) memory kit prices start at $165, while 32GB (2x16GB) variants retail for $219. A decent DDR4-4000 memory kit costs half as much as a DDR5 memory kit. However, we knew ahead of time that AMD’s move to his AM5 socket would come at a small price due to the chipmaker’s decision not to keep DDR4 support on Zen 4..the shortage is gone but DDR5’s Manufacturing costs are still high. Nevertheless, AMD is optimistic that his DDR5 supply and pricing will continue to improve.
As always, we recommend choosing dual DIMM memory kits over quad DIMM configurations for your Ryzen 7000. For example, AMD only guarantees DDR5-5200 support on his 1DPC (DIMM per channel) configuration. In 2DPC scenarios, the official memory speed drops to DDR5-3600.
AMD’s Ryzen 7000 processors hit the retail market on September 27th along with new 600-series motherboards and EXPO-certified DDR5 memory.
