noob ram OC questions

[ipam45]

i read a few guide on ram overclocking and to my understanding it would be useless to overclock your ram unless your FSB passes it's suggested speed...right?

my ram is ddr2 800 so it;s running at 400mhz, so unless my FSB passes 400...which it doesn't, it should be a problem and there shouldn't be any performance decrease?

thanks

isn't ddr2 quad pumped? 4x200mhz = 800mhz??
