The LRDIMM Advantage: Memory Buffer Magic

The standout feature of LRDIMM is its memory buffer chip. This component minimizes the memory bus load by reducing clocks, commands, addresses, and data input to a single load. While this doesn't necessarily make LRDIMMs superior to RDIMMs in all aspects, it significantly enhances memory speed.

LRDIMM vs. RDIMM: A Comparison

To better understand LRDIMM, let's compare it to its cousin, RDIMM:

  1. Capacity: LRDIMMs offer higher memory density
  2. Power: LRDIMMs are generally more power-hungry
  3. Speed: RDIMMs have a slight edge in speed
  4. Cost: LRDIMMs are typically more expensive
  5. Latency: RDIMMs provide lower latency
  6. Load and power consumption: LRDIMMs excel in reducing both during operation
  7. Buffer complexity: LRDIMMs use a simpler memory buffer, while RDIMMs employ a more sophisticated register
