Question about my 1900GT

i've had my 1900GT for a while now, but noticed in ATI tool it says for core i have 513mhz and for mem i have 657 mhz. but at a place like tomshardware, it says my 1900GT is 580 and 1100 mhz. what is going on?? something wrong with my card? is it underclocked some how or getting read wrong, is it working poorly, whys it not what it is supposed to be? it is the sapphire 1900gt if that makes a differencencderek

Yep you are right different brand has different clock-speed

so sapphire is probably a cheaper and underclocked version of the 1900?ncderek

Nope saphire is the default version. The one you saw on the review was the OC version

You got the X1900GT rev. 2, which featured lower clock speeds than the original X1900GT.
