  6. Although DDR & initial RAMBUS RIMMs have the same pin count (184 pin), they are keyed differently and therefore these disparate RAM Module Technologies are not Memory Slot compatible. The RAMBUS Data Rate = RIMM Speed. Newer RAMBUS Rimms (PC1066) have 232 pins.
  7. Dual Channel DDR: When Dual Channel DDR Technology is activated, the bandwidth of Memory Bus will be double the original Memory Bus, with the fastest speed at 6.4GB/s DDR400. To activate Dual Channel DDR Memory, two DDR Memory Modules are inserted individually, one each into Channel A and Channel B.
