Memory speed vs capacity

Memory speed isn’t often a consideration when building a system except for those seeking ultimate Overclocking performance. While OC memory exceeds the JEDEC standards, there are other considerations which may rob you of maximum performance.

I will discuss memory technologies ranging from DDR2 FB-DIMM to modern DDR4 ECC memory and how CPU memory controller limitations affect the actual performance you can expect. The TL;DR is that when you add more DIMMs per channel or more ranks, the memory frequency goes down.
