its ddr memory so double the freq. and wala!! its like ddr400 memory -- freq. will be 200- but that will make effective freq. 400.

nothing to worry about, everything is at it should be.

GDDR3 Double Data Rate, that's perfectly normal 715 GDDR3 x 2= 1430 effective speed.

1430MHz = your DDR speed. This means your memory is actually running at 715MHz, but since it's DDR RAM, it processes on both the rise and fall of the clock signal. This means it basically runs 2x faster..

So basically, 1430MHz = DDR speed, 715MHz = Real speed.
