For a two DRAM module population:

Download Memtest86+ V2.01 from--->

Download CPU-z from--->

Shut the system down. Insert a stick of DRAM in Slot 1 (Closest to the CPU) and slot 3. Restart, Enter your BIOS and Load Setup Defaults. Save Setup Defaults and set to these values:


Enter your BIOS. On the main BIOS screen press Ctrl + F1. You will see the screen flicker. Next select the MB Intelligent Tweaker option. On that screen you will see many additional settings that were not there before.
