how many passes?
anyway... why is the disparate ram a no no? while i've got the time................ ...... ...... ......
Dual channel works in a form of 'interleaving'.
Much like a RAID 0 system in harddrives.
lets say we have a stream of data that needs to be used/processed.
Very simplified here, but in single channel, the data goes:
bit 0 to gate 0 of stick 0
bit 1 to gate 1 of stick 0
bit 2 to gate 2 of stick 0
etc
In dual channel, in the same amount of time, the data goes
bit 0 to gate 0 of stick 0, bit 1 to gate 0 of stick 1
bit 2 to gate 1 of stick 0, bit 3 to gate 1 of stick 1
bit 4 to gate 2 of stick 0, bit 5 to gate 2 of stick 1
As you can see, we theoretically have doubled the amount of 'work' being done.
Having two different sticks means they cant synch up
