Additional Details:

The HMT451U7DFR8A-PBT0 module conforms to industry-standard DDR3 specifications, ensuring compatibility with a wide range of server and workstation platforms that support DDR3 unbuffered ECC memory. The 'PC3-1600' designation indicates that it is designed to operate at a clock speed of 1600 MHz. Its single-rank configuration allows for simplified memory access. The 1.5V operating voltage contributes to energy efficiency. Unlike registered ECC, unbuffered ECC memory modules do not have a register between the memory controller and the DRAM chips. This reduces latency, but may also reduce maximum capacity or stability in some systems.
