AMD’s Ryzen 7000 processors (like their predecessors) will also have an ideal memory configuration which will offer the best performance in gaming and latency-sensitive workloads. According to WCCFTech, DDR5-6000 will be the sweet spot for these CPUs with the memory and Infinity Fabric running in a 1:1 setup. This means that the IF and the memory when run set to 3,000MHz or 6,000MT/s will deliver the optimal performance.
If the memory speeds are set over 3,000MHz, then the memory configuration is set in a 2:1 configuration. The Infinity Fabric will run at half the speed, i.e: 1,500MHz, However, as with Matisse and Vermeer, this will result in relatively poor performance on account of the large delta between the two interconnects. This is very similar to Intel’s Gear 2 and Gear 4 modes that represent the 2:1 and 4:1 DIMM: controller configurations.
Interestingly, the X670 and X670E boards haven’t been specifically tuned for memory overclocking. That honor will go to the B650E motherboards. While both the X670 and X670E family will support both overclocking and underclocking, the exact extent will completely depend on AMD.
