You're unsure about the meaning of "Rank," since both kits were in dual channel.
memory sticks come in various configurations—single rank, dual rank, and quad rank, though the latter is uncommon and not fully supported. Processing data requires time for chips to handle requests and send them to the CPU. Dual rank sticks allow the memory controller to begin transferring data from one rank while issuing a command for the other, reducing overall latency. This improves bandwidth slightly by minimizing wait times. Dual channel operates by handling requests from both sticks at the same time, but when both are single rank, the CPU must wait for both to be ready before sending data. Single rank is simpler for the controller, making it preferable for overclocking and high-frequency use, while dual rank offers a marginally better bandwidth potential.
Usually single-rank memory uses ICs on just one side of the stick, while dual-rank has them on both sides. Some exceptions exist, and a few dual-rank sticks still keep ICs on only one side. Generally, adding more RAM slightly boosts bandwidth but reduces the maximum operating clock speed and affects the memory controller. For motherboards with four slots: use single-rank when you have two dual-rank sticks in dual-channel mode, switch to dual-rank with four single-rank sticks, dual-rank with two dual-rank sticks, and quad-rank with four dual-rank sticks. For reference, I use four 16GB dual-rank sticks in quad-rank, achieving about 4–5 GB/s higher bandwidth than two 8GB single-rank sticks under the same conditions. Performance matters most for copying and latency, which are crucial for gaming. This setup uses a 3800MHz CL14 Samsung die in dual-channel/single-rank configuration. I’m using a 3733MHz CL16 Micron die (lower clock speed, higher latency) in dual-channel/quad-rank configuration.
