Various memory module brands will launch various frequency (e.g. DDR5 6000~8000 MT/s) specifications or different CL value specifications under the same frequency to sell. Basically, high-end models will pursue the optimization and advancement in these two directions, but both high frequency and low CL value will further increase the price of the product because not every batch of chips can be conformed to the requirements at will. High frequency or low CL mass production...
