Product Description
The Hynix HMT41GU7AFR8C-H9T0AB is a high-density 8GB memory module designed for use in servers and workstations that support DDR3 Unbuffered DIMM (UDIMM) technology. With a capacity of 8GB, it significantly enhances a system's ability to handle multitasking, run memory-intensive applications, and process larger datasets more efficiently. DDR3 technology represents a generation of SDRAM that offered improvements in speed and power efficiency over its predecessor, DDR2, making it a popular choice for computing platforms of its era. This module operates at a frequency of 1333MHz, commonly referred to as PC3-10600. This speed dictates the rate at which data can be transferred between the memory and the system's processor. The CAS Latency (CL) is rated at CL9, meaning it takes 9 clock cycles for the memory to respond to a column address strobe command. A CL9 rating at 1333MHz is a standard and reliable performance characteristic for DDR3 memory. The module's organization as 2Rx8 signifies that it is a dual-rank module. Dual-rank modules contain two independent sets of memory chips (ranks) on the same module, which can sometimes offer performance benefits by allowing the memory controller to interleave accesses between the ranks, although this depends on the specific motherboard and memory controller implementation. As an Unbuffered DIMM (UDIMM), this module does not contain an onboard register chip to buffer command and address signals. UDIMMs are commonly found in desktop computers and many entry-level to mid-range servers. While the title does not explicitly mention ECC (Error-Correcting Code) functionality, many server-grade UDIMMs do support ECC, which is vital for detecting and correcting memory errors to ensure data integrity in critical server operations. Users should confirm system compatibility and specific memory requirements, including ECC support, before installation. The standard operating voltage for DDR3 memory is 1.5V.
