Product Description
The Hynix HMT451V7BFR8A-PBT8 is a 4GB DDR3 Very Low Profile Registered DIMM (VLP RDIMM) module, engineered for server and networking applications where space is a critical constraint. The VLP form factor allows for installation in densely packed server chassis, such as 1U rackmount servers, where standard height DIMMs would not fit. Despite its low profile, it retains the performance and reliability features expected from server-grade memory. This module operates at a speed of 1600MHz, designated as PC3-12800, providing enhanced data transfer rates for improved system responsiveness. It features a CAS Latency (CL) of 11, which is a common timing for DDR3 modules at this speed, offering a good balance between latency and bandwidth. The organization is 1Rx4, meaning it has a single rank with a 4-bit data width per chip. This configuration is often used in specific server designs that require a particular memory architecture. As a Registered DIMM (RDIMM), it includes an onboard register to buffer command and address signals, reducing the electrical load on the memory controller and enabling higher memory capacities and system stability. The HMT451V7BFR8A-PBT8 also supports Error-Correcting Code (ECC) functionality, which is vital for detecting and correcting memory errors to ensure data integrity and system uptime in critical server environments. It operates at the standard DDR3 voltage of 1.5V.
