RAM Single Rank vs Dual Rank - Ryzen 5 5600x + RTX 3080 10 Games 1080p and 1440p

What is memory rank? A memory rank is a block or area of data that is created using some, or all, of the memory chips on a module. A rank is a data block that is 64 bits wide or 72-bit wide in the case of ECC modules. Depending on how a memory module is engineered, it may have one, two, or four blocks of 64/72-bit wide data areas. This is referred to as single-rank, dual-rank, and quad-rank. Having a dual- or quad-ranked module is like having two or four DRAM modules combined onto one module. On AM4 platform when using 2 single rank modules memory will operate in dual channel mode, configured as single rank. When populating all 4 memory slots with single rank modules, memory will still operate in dual channel mode but it will be configured as dual rank. When using 2 dual rank sticks memory will work in dual channel mode, configured in dual rank. When using 4 dual rank modules memory will operate in d
