Hello NIK111,

Yes, you need to change an option in the BIOS.

- Access BIOS

- Click on the Frequency/Voltage Control option.

- Under Memory Ratio select 10

- Hit the F10 key to save and exit

- Test the system with the CPUz tool, should be running at 800MHz

I did what you said,I set the Memory Ratio to10 and in cpuz it still shows the 1600 ram as 1333.
