[BB1]

hiya,
bought a pre built pc 6 months ago...
asrock wolfdale 1333-ddr2 667 A2
E8500
Sapphire 4870 512mb
4 GB ddr2 667
620w PSU
Vista Home Basic

Would any 1 know if the board will prevent me from overclocking cpu as its only rated for a 1333fsb. any help much appreciated.

mobo will limit, but not prevent. however, that ram is really gonna hurt you, only being 667. unless its top dollar stuff, which I doubt, since there is little if any top dollar ddr2 667 ram >.<
