Description
The Random-Access Memory (RAM) speed (frequency) shows a lower value than the maximum memory speed supported by the Intel Processor.
Resolution
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:
- Check if the memory RAM modules are installed in the proper configuration/slots per the computer user's manual.
- Verify the memory is using the correct SPD profile in the BIOS/UEFI.
- Consult the computer user's manual or with the original equipment manufacturer (OEM) for proper BIOS/UEFI.
- Review the memory RAM module's compatibility with the motherboard. For instance, reviewing the motherboard's Qualified Vendor List (QVL).
- Make sure the memory RAM is supported for the Intel Processor.
- Enter the processor number in the search box on the product specification page (ARK)and click Enter.
- Look for the Memory Specifications section. The supported memory for the product is listed under Memory Types.
