HOW FAST CAN YOU GO WITH DDR5 OR DDR4 ON THE NEW PLATFORM AND WHAT ABOUT MEMORY CONFIGURATION OPTIONS?
For DDR4, it's pretty much status quo to 11th Gen Core processors with dual memory modules supported per memory channel at speeds up to DDR43200. So that's a total of four DIMMs for a typical setup. With DDR5 memory, Intel states you can get frequencies as high as DDR5-4800. However, the memory frequency supported is dependent on other factors like a) how many slots are provisioned per channel on the motherboard, b) how many DIMMs are populated per channel and c) if it is a single rank or dual rank DIMM memory module. Intel has compiled this table for a quick reference:Taking into consideration all the mentioned factors, your DDR5 memory frequency can range from anywhere between 3,600MT/s to 4,800MT/s. Some other notes that are good to keep in mind is not to mix memory varieties/brands within the same channel and symmetric configurations are required within the same channel, i.e. single rank or dual-rank DIMMs on both slots (1R/1R, or 2R/2R). Now, these are just the official memory speeds as supported by Intel officially. However, given the right motherboard, the right memory modules and memory configurations, you could go way higher than the frequencies listed here. A peek at Gigabyte's top Aorus motherboard's memory speed options go higher than 7,000MHz! So that brings us to the next topic of memory overclocking.
