Change the DRAM Frequency and DRAM Voltage in the machine's BIOS.

So do I have a DRAM misconfiguration it the BIOS on my machine because "actual" value doesn't match the "spec" value? Correct?

You can use `sudo dmidecode -t memory` to see part numbers.

For whatever reason BIOS decided to use 933MT/s. It would be best to look up specs for your actual DRAM model and find out supported frequencies. Then in BIOS > Ai Tweaker menu > Memory Frequency select supported frequency. N.B.: find where on your motherboard a CMOS clear jumper is, in case you need to reset BIOS to default...
