DDR3 1333 (OC)?

[FerdZ07]

I have an Asus P5G41TM-LX3 mainboard which supports DDR3 1333 by OC and I have a 1066FSB Pentium E6600 and 2 gigs of Kingston DDR3 1333 module to be installed. The user manual under the DRAM frequency options table shows a 1066FSB CPU can be set at 1067mhz max and there's a warning that states: " setting a very high DRAM frequency may cause the system to become unstable. If this happens, revert to the default setting". In this case, how can I set it to DDR3 1333mhz (by OC) without any possible instability? I'm really confused about this. Any answer shall be appreciated. Thank you.

There is not a option to set memory freq in BIOS to 1333 ? Overlocking CPU to get 1333 MHz on memory doesn't have a sense to me.
