Set your RAM back to 667MHz and boot-up. Download and run CPU-Z: http://www.cpuid.com/cpuz.php
What does CPU-Z show on the Memory tab under DRAM frequency? If it says 667MHz you have to double that to match the rated spec the manufacturers promote. 667 x 2 = 1333
If your BIOS is set to 667MHz and CPU-Z shows 667MHz, then you want to set your RAM at 800 to get the manufacturer's 1600 MHz.
The "9-9-9-24" refers to the first four settings under DRAM timing control. Set those values and leave the rest on Auto.
