The Random-Access Memory (RAM) speed (frequency) shows a lower value than the maximum memory speed supported by the Intel Processor.
The default memory operating frequency is automatically configured during the initial Power On-Self Test (POST) process. In most cases, the motherboard reads the Serial Presence Detect (SPD) module previously programmed in each memory stick by the memory manufacturer to set the memory's operating frequency.
The SPD configuration may be programmed at a lower frequency than the vendor-market value to support wider compatibility. (For example, the memory may be rated to run at 3200Mhz but the SPD default is set by the manufacturer at 2400Mhz.)
To change the configuration, follow the steps below:
