Mate, someone telling you this has no idea what they are talking about or have explained themselves very poorly.
Intel utilises FSB via the Northbridge for memory control unlike AMD who have the memory controller "on die" (as will intel with nehalem aka i7)
To run at DDR2 667MHz your Bus speed would have to be set to 333MHz in the bios (quad pumped = 1333MHz Rated FSB)
Currently I would assume it is set to 400MHz if it is 1:1 FSB: DRAM ratio, ergo DDR2 800MHz (quad pumped = 1600MHz Rated FSB)
Your memory is DDR (Double Data Rate) so with 400Mhz set in the bios you'll get DDR2 800MHz
Perhaps the confusion has arisen between the Bus Speed and the Rated FSB somewhere along the line.
There is no way you're going to be able to run a Bus speed of 667MHz (hell the world record is 734MHz or thereabouts done with LN2 sub zero cooling) as it would give a 1:1 DDR rate of 1333MHz and a Rated FSB of 2668MHz.
DDR 1333MHz is in the realms of DDR3 modules such as the ones I have.
