Frequently Asked Question - When I compare a system information gathered from BIOS with system information gathered from SMBIOS, they are substantially different. Is one more accurate than the other?

When I compare a system information gathered from BIOS with system information gathered from SMBIOS, they are substantially different. Is one more accurate than the other?

BIOS system information reports will occasionally show a difference in information for specific devices compared to the same device found in an SMBIOS system information. This is because the SMBIOS information for a device is provided by the device vendor. If there is a discrepancy in device information between BIOS and SMBIOS, it will probably not affect performance. However, it might indicate that the BIOS vendor or system (motherboard) manufacturer did not take the additional steps to ensure that the BIOS information was correct. The real value in this is seeing SMBIOS information in a Service Center system information report without having to reboot the system and access the BIOS directly.
