I am not familiar with the Asus BIOS, but somewhere in there is some kind of memory setting. Experiment until you find something that gives you a memory clock setting of twice the FSB. At that point CPU-Z should indicate a memory clock of FSB X 2 or 622 MHz. and an FSB:memclock ratio of 1:1.
Then continue to work the FSB upward, increasing the CPU core voltage if you need to. Keep the core voltage under Intel's recommended max of 1.500 volts and keep load temps below 70 C. ----------
Overclocking since 1978 - Z80 (TRS-80) from 1.77 MHz to 2.01 MHz
