Citing a leaked slide, VideoCardz reports DDR4-4000 may be the new memory sweetspot for overclockers on the upcoming AMD Ryzen 5000 platform. The Zen 3-based CPUs were revealed last week and will hit the market on November 5. If the slide is real, DDR4-4000 will be for Zen 3 what DDR4-3800 was for Zen 2:
The Zen3 architecture will feature 1:1:1 ratio for each clock speeds. It is up to the user to configure the frequencies for best memory and system performance. The alleged slide also explains that DDR4-4000 memory is to Zen3 (Ryzen 5000) processor what DDR4-3800 was to Zen2 (Ryzen 3000 series).
