Check the units and active settings before changing XMP or EXPO. A kit’s advertised rate is not a guarantee that every CPU, motherboard and module combination can run it. First, decide whether the numbers really disagree Open Task Manager → Performance → Memory and note the speed label, value and total capacity. If you use CPU-Z from CPUID, its Memory tab reports the active DRAM frequency. The SPD tab describes module information and stored profiles; seeing a faster profile there does not mean it is currently enabled. ...
