Does the 9800 GT really have 1800MHz of memory?

[finn92]

help me out here
i need to know cuz i'm plannin to buy it
i heard that it has 1800 MHz but i also heard that it only has 900 MHz

1800Mhz is the effective clock, 900Mhz is the real clock. DDR = Double Data Rate.

what's the difference?

well the 900mhz is the real clock and the 1800mhz is how fast it is with the ddr. it really doesnt matter. if your planning on buying it, this has nothing to do with whether or not to buy it.
