AMD Memory Profile can improve performance, but it depends on your system. If you're experiencing slowdowns, enabling it might help. Otherwise, stick with the default settings unless you notice a difference.
Generally, smaller numbers are preferable. But since delays are expressed in clock cycles, you need the frequency to compare them accurately. A larger cycle count at a higher frequency can result in lower actual latency than a smaller count at a lower frequency. For instance: - A CL of 16 (clock cycles) at 3200 MHz equals 10 nanoseconds - A CL of 18 (clock cycles) at 3600 MHz also equals 10 nanoseconds Thus, the true latency remains consistent despite the differing cycle values.
CL 11 at 1600 MHz translates to roughly 13.75 nanoseconds, and CL 12 at 1866 MHz is about 12.86 nanoseconds. The adjustment appears minor, likely not significantly affecting performance, though it shouldn't be ignored entirely. Running benchmarks before and after would help confirm the actual impact.
Looking for a clear guide on latency and how to compute it? I can suggest some helpful resources.
TL;dr: CPU delays data transfer to RAM, measured in clock cycles. Higher RAM speed means shorter cycles or higher frequency. To reduce latency, either decrease cycle count or increase frequency. For DDR RAM, the listed clock rate is effective, not physical. Actual performance depends on using real cycles, not just MHz. Converting to nanoseconds per cycle helps calculate precise latency.
