DDR means Double Data Rate, meaning it performs actions on the rising and falling edges of clock signals. The frequency you usually see advertised for RAM is actually the EFFECTIVE frequency (I.E. DDR4 3600). The ACTUAL frequency is going to be half that (DDR4 3600 actually runs at 1800 MHz). inb4 someone corrects that it's not actually frequency and MT/s or whatever, not going that deep right now

Really wish it would have went QDR although I still like a lot of the changes, especially the read & writing at the same time. I think QDR would bring an even more significant performance difference. GDDR5X is QDR for example.
