Different memory clock then site says GTS450?

http://www.newegg.com/Product/Product.as…

i just bought this the other week.the sites clearly says it has a 4k memory clock why is it im only getting 2k memory clock and it still at default is this a typo on the site or whats the problem.

just trying to get down to the bottom of this.

and that is the exact one i bought from that link at that?|||the memory clock is multiplied depending on architecture



the memory clock shown on wedsites is the effective memory clock.



ATi architecture runs memory clocked between 1000mhz and 1200mhz but runs on 4 channels so clocks between 4000mhz and 4800mhz



nvidea has 2 channels to clocks at 4000 mhz effectivly but the memory is actually at 2000mhz
