I am using Intel DH77DF motherboard in my computer and it has three RAM sticks attached ion it. All these RAMs are of different types with different specifications. I am trying to get the RAM to work on frequency of 1600 MHz at power supply of 1.5 V. All these RAMs are of DDR 3 type. To perform this, I accessed the BIOS and under performance section, I checked memory. It was showing the frequency of RAMs as 1333 MHz ay 1.8 V. After seeing such a high voltage, I changed the profile from ‘Auto’ to ‘XMP’. I reduced the voltage, but also had to reduce the frequency. Can someone tell me if the previous voltage were right for the Intel DH77DF motherboard or was it some display bug showing improper values?
