XMP is a preset built into the memory that sets your ram to its rated specs, in the bios you set the AI Overclock Tuner to XMP and you're done. One draw back is, it often times over volts the cpu system agent voltage and cpu vccio voltage which can contribute to higher cpu temps. After enabling XMP, set these two voltages to 1.15v which should be enough or up to 1.25v if needed.
It is also easy to set your ram manually which most prefer.
Could you please be so kind to tell me the step-by-step procedure of BIOS settings to alter/enter after booting up for first time with these memory sticks installed?
