would this affect how much i could overclock

[paradisiac]

ok, looking at getting

Key Features:

* Module specification 240Pin Unbuffered DIMM Non ECC

but i dont want it to limit what overclock i can achieve with my x6 when i get it, so would the fact this is only 1333MHz limit the amount i can increase the fsb settings and stuff for the cpu (im guessing cpu-ram works on a ratio system).
