Asus AMD Radeon HD6770 DCU Ram clock
 
i juz wondering that anyone could answer why my GPU Asus AMD Radeon HD6770 DCU ram clock is lower than its twin Asus AMD Radeon HD6770 with no DCU...my GPU has 1GB DDR5 with 4000MHZ while normal HD6770 Asus has 4800MHZ?...doesn't this make my GPU has lower perfomance?

Since your card has 128 but memory bus the memory speed is kinda critical, but since it's a mid range card it really depends on your specific scenario (game, resolution, other system components, etc). You can try overclocking the card and it's memory with MSI Afterburner - you should be able to raise both clocks by 10% without increasing the voltage (just remember to set the catalyst power tune to max performance).

why MSI afterburner?...i got SmartDoctor asus software...can't it be used for O.C my GPU?...

It can, but I've never used it, so Afterburner could be my best advice :)

I would also suggest afterburner, awesome and simple utility.
