from my understanding they are divided by ur htt (which is an amd fsb right?) to give u ur ram clock speed in mhz? is that right
the difference between the FSB and the HTT is this:
Intel chips have to use a memory controller on the motherboard in order to communicate with RAM.
the FSB (Front Side Bus) is the speed between the CPU, and the memory controller.
However AMD's K8 chips have the memory controller on the CPU itself, so they don't need a FSB.
Instead, they can communicate directly with the RAM. (which is faster)
the HTT (HyperTransport) bus is the communication speed between the CPU and the memory.
Now, as for memory dividers:
Your RAM will run at a speed proportionaly to the FSB or HTT
the HTT bus at stock runs at 200MHZ (x5)
If you have DDR400 RAM, it will run at 200MHZ also
If you increase the HTT to 250, the RAM will also run at 250 (or DDR500)
A RAM divider just basically makes the RAM run slower, compared to the HTT bus
If you have a 5:3 ratio, it means that your RAM is running 5/3 of the HTT speed
which means if the HTT bus is at 200MHZ, your RAM will run at DDR333MHZ
