7. Turn on the relevant clocking options.
8. Select your memory initialization options.
9. Select your memory controller options.
10. Turn on the relevant DLL reference clock options.
11. Click the Controller Timings tab.

For more information on controller timings, refer to “Controller Timings”
12. Enter your memory timing parameters in the Required column, so that the
controller timings meet the requirements specified on your memory’s datasheet.
The wizard picks the appropriate number of clock cycles between commands that
are needed and calculates the resulting delay in the Actual column.
