The HMT451U7AFR8C-PBT0 is a DDR3 unbuffered ECC memory module made by Hynix Semiconductor. These modules are designed for use in workstations and entry-level servers to provide data integrity and reliability. Unbuffered memory modules lack a register between the DRAM and the memory controller, which can make them less stable in high-density or heavily loaded systems.

Applications:

• Workstations
• Entry-level Servers
• Desktops requiring ECC Memory

Features:

• DDR3 Technology
• Unbuffered ECC DIMM (UDIMM)
• Module Size: 4GB (1 x 4GB)
• Module Rank: 1Rx8
• Speed: PC3-12800 (DDR3-1600)
• CAS Latency: CL11
• Voltage: 1.5V
• 240-Pin DIMM

Benefits:

• Enhanced Data Integrity: ECC (Error-Correcting Code) detects and corrects single-bit memory errors, preventing data corruption.
• Improved Performance: DDR3 technology provides faster data transfer rates compared to previous generations, which leads to improved performance compared to older memory types.

Additional Details:

The HMT451U7AFR8C-PBT0 module conforms to JEDEC standards. The 'PBT0' likely signifies a specific manufacturing batch or revision. Always consult system or motherboard documentation to ensure compatibility and optimal performance. ECC memory provides a degree of protection against data errors. The module is built with components to ensure reliable performance.
