RAM for ASUS M4A78LT-M motherboard

[sonic_boom81]

I'm considering upgrading my ASUS DDR2 motherboard to an ASUS M4A78LT-M DDR3 motherboard.

Looking online for compatible RAM Crucial says that 1600MHz DDR3 is fine, but the motherboard specifications say:

"4 x DIMM, Max. 16GB, DDR3 1800(O.C.)/1600(O.C.)/1333/1066 Hz ECC, Non-ECC, Un-buffered Memory - Dual Channel Memory Architecture"

I'm not sure how to overclock the RAM, or if the RAM recommended by Crucial would work straight away? Or should I just stick to 1333MHz RAM? Do I need to buy RAM that is 'overclockable'?

That is max rated speed, it can and will drop down to speed CPU and MB require.

Should boot to the mobos default (1066), from there it depends on the CPU what data rates you can actually run at
