I would strongly suggest to update the Bios version on non OC'ed settings to version 1.3 or even 1.4
Normally 9 x 333 with Ram at 1333MHz should be a no brainer... However the ASROCK doesn't support Cas 11
Follow these steps for the OC TWeaker Bios page and see if it boots and is stable
1) Set RATIO CMOS Setting to 7 (later you can move up to 9X mutliplier )
2) Overclock Mode to Manual
CPU Frequency to 333
PCIe Frequency to 100
3) After setting the above set the DRAM frequency to 1333
4) DRAM Voltage to 1.55
5) Press F10 Save and reboot
