In a 2DPC scenario, the official memory speed drops to DDR5-3600. Im afraid if I do buy the RAM now newer and faster RAM optimized for Zen 3 will come out later. nn and monitor 1 09 EGA Video EGA Card 640 x 350 pixels, 256KB Display RAM. RAM for Zen 3 Discussion Would it be a good idea to get RAM for Zen 3 from now I’m coming from an Intel i7 5820k and this will be my first AMD build. For example, AMD only guarantees DDR5-5200 support on a 1DPC (DIMM per channel) configuration. 63 8M Hz Speed AT Style Keyboard Phoenix BIOS 1.2MB Floppy Drive. Dual-DIMM setups are better for signal routing and less stressful on the processor's IMC (integrated memory controller). Nevertheless, AMD is optimistic that DDR5 supply and pricing should continue to get better.Īs always, it's recommended to choose a dual-DIMM memory kit over a quad-DIMM configuration for Ryzen 7000. There aren't any shortages anymore, but it's still more expensive to produce DDR5. Although pricing for DDR5 has improved over the last few months, it still carries a significant premium over DDR4. However, we already knew beforehand that migration to AMD's AM5 socket commands a small fortune due to the chipmaker's decision not to maintain DDR4 support on Zen 4. A decent DDR4-4000 memory kit costs half of a DDR5 memory kit. We'll take AMD's word until we can run our RAM benchmarks on Zen 4.Ĭurrent DDR5-6000 16GB (2x8GB) memory kits start at $165 whereas the 32GB (2x16GB) offerings retail for $219.

Nonetheless, Hallock said that in some scenarios, when surpassing a 2,000 MHz FCLK could yield better performance. In contrast, Zen 3's sweet spot was at DDR4-3600 (1,800 MHz FCLK), with DDR4-4000 (2,000 MHz FCLK) being the golden standard. Notably, AMDs new Zen 3 architecture has vastly improved single-core performance and lower memory latency, which leads to a significant effective speed. Hallock believes that DDR5-6000 will be the sweet spot for Zen 4 based on cost, stability, performance, availability, and ease. The Zen 4 parts have a default FCLK of 1,733 MHz, supporting DDR5-5200 memory by default. As a result, the best configuration is Auto:1:1. B550 Ryzen 5000 Ryzen 9 5950X Ryzen 9 5900X Ryzen 7 5800X Ryzen 5 5600X 339 Comments New and Improved Instructions When it comes to instruction improvements, moving to a brand new ground-up core. Instead, he recommends users leave the FCLK on the auto setting and overclock the DDR5 memory modules and the memory controller in a 1:1 ratio. For starters, Hallock confirmed that it's no longer essential to maintain a 1:1:1 ratio with the Infinity Fabric Clock (FCLK), unified memory controller clock (UCLK), and memory clock (MEMCLK). Hallock commented on AMD's official Discord channel (via Bionic_squash) that memory overclocking on the Ryzen 7000 processors differs slightly from the previous Ryzen 5000 (Vermeer) chips.
