This relationship is fundamental to correctly interpreting the memory’s operating speed. Misunderstanding this doubling effect leads to incorrect assessment of XMP activation.
-
Verification Against Advertised Speed
The advertised memory speed, usually found on the memory module’s packaging, represents the effective clock rate. When verifying XMP status, the effective clock rate derived from CPU-Z (2 x DRAM Frequency) must align with this advertised speed. A significant discrepancy indicates that the memory is not running at its intended speed, suggesting XMP is disabled or not functioning correctly. A memory kit advertised as 3600 MHz should display a DRAM frequency near 1800 MHz in CPU-Z when XMP is enabled.
-
BIOS Configuration and Rate Adjustment
Enabling XMP within the system’s BIOS automatically adjusts the DRAM Frequency and timings to achieve the advertised effective clock rate. After enabling XMP, CPU-Z provides a means to confirm whether the adjustments have been successfully applied. If the DRAM Frequency does not increase to reflect the intended effective clock rate after enabling XMP, it suggests a problem with the BIOS settings, memory compatibility, or system stability. Monitoring the effective clock rate post-BIOS change is necessary for validation.
-
System Performance Implications
The effective clock rate directly impacts system performance, particularly in memory-intensive applications like gaming, video editing, and scientific computing.
