You're seeing a trade-off between speed and stability. Higher frequencies like 3600MHz can offer better performance but may introduce more latency. Lower frequencies such as 3200MHz provide lower latency but might sacrifice some throughput or efficiency. It's about balancing your needs based on what matters most for your application.

They are almost identical. The 3600 is likely to be slightly improved by about 1% in certain games.

Timing isn't the same as latency. The mix of frequency and timing determines latency. This level matches similar latency at a higher data speed. Relevance varies based on CPU, board, and cost.

I'm sorry for the oversight. It's good to have secured a better deal on the 3600. It turned out to be more economical than expected.

There are numerous factors influencing RAM latency beyond the standard 3 to 5 values. It’s easy to become overly complex. The timing details describe the number of clock cycles needed for a task. The MHz value represents twice that cycle count over a specific time span, which explains the “double” in Double Data Rate. To figure out actual latency from these figures, you can work through examples: For instance, at 3600MHz divided by 2 equals 1800 MHz cycles per second. Dividing 1000 by 1800 MHz gives about 0.5556 nanoseconds per cycle. Multiplying by 18 cycles per clock gives roughly 10 nanoseconds of delay. Another case: 3200MHz divided by 2 is 1600 MHz, and 1000 divided by 1600 yields 0.625ns per cycle. Multiplying by 16 cycles results in 10 nanoseconds. In both scenarios, latency remains consistent. Choose higher-speed RAM for better overall data throughput. If timing options were 20 MHz versus 15 MHz, it might make sense to pick the slower ones to minimize latency—though this rarely pays off, as higher clock speeds usually match or improve timings.
