Is it total 6gb @1333mhz? If it is it counted as fast or slow? Sorry i not really good all this things...
Dual channel means that two DIMMs are accessed in parallel, doubling the (theoretical) bandwidth.
I believe that 1333 MHz is the fastest standard specification. There is memory available with higher clocks, but it's outside the standard. (That's true for Intel motherboards. I don't know if it's the same for AMD.) I doubt that most laptops would have the BIOS adjustments needed to set the RAM to higher frequencies.
6GB is a peculiar number. DIMMs are usally made in powers of 2, so that usual capacities are 1, 2, and 4 GB. To get 6 GB dual channel, that suggests two 2 GB plus two 1 GB DIMMs.
