Additional Details:

The HMT84GR7AMR4A-H9D3 memory module adheres to industry-standard DDR3 specifications, ensuring compatibility with a wide range of server platforms that support DDR3 registered ECC memory. The 'PC3-14900R' designation indicates that it is designed to operate at a maximum transfer rate of 14900 MB/s, corresponding to a clock speed of 1866 MHz. The quad-rank configuration allows for maximum memory bandwidth utilization through interleaving of data across the four ranks. The 1.5V operating voltage contributes to power efficiency. The H9D3 indicates a specific revision or production lot of the memory module, likely related to specific manufacturing processes or component variations. The Registered (or Buffered) DIMM has a register between the DRAM modules and the system's memory controller which helps stabilize electrical signals, allowing for higher densities and faster speeds.
