XMP combined with MHz changes (raising or lowering the frequency)
The board won't automatically modify CAS or other main timing settings when XMP is active because CAS isn't set to auto. Still, some secondary and tertiary timings will update automatically if you adjust the RAM frequency. The latency doesn't simply get reduced to match; instead, actual timing values change. In theory, latency stays consistent, but in reality it can vary—either drop or rise—depending on frequency shifts and timing adjustments.
Yes, it’s unusual. The original timings were adjusted to a different frequency, which can affect stability and performance. Such changes aren’t typical unless there was a specific reason or issue.
I haven't adjusted the settings yourself. Could you share your board model and RAM specifications?
