Hynix HMT125U7BFR8C-G7T0-AA-C 2GB DDR3-1066MHz UDIMM 2Rx8 CL7 Memory

Product Description

The Hynix HMT125U7BFR8C-G7T0-AA-C is a 2GB DDR3 Unbuffered DIMM (UDIMM) memory module. It operates at a clock speed of 1066MHz, corresponding to the PC3-8500 standard, and is designed for use in desktop computers and some entry-level servers that support unbuffered memory. Unbuffered DIMMs (UDIMMs) do not have an onboard register chip; instead, command and address signals are sent directly from the memory controller to the memory chips. This architecture is simpler and less expensive than Registered DIMMs (RDIMMs) but places a higher electrical load on the memory controller, limiting the total number of modules and overall capacity a system can support. This module is configured as 2Rx8, indicating it is dual-rank and uses memory chips with an 8-bit data width. Dual-rank modules can offer improved performance over single-rank modules by allowing the memory controller to access different ranks in an interleaved fashion, potentially increasing bandwidth. The CAS Latency (CL) is rated at 7, which is a relatively low latency for DDR3 memory, contributing to quicker data retrieval. Unlike RDIMMs, standard UDIMMs typically do not feature ECC (Error-Correcting Code) functionality, making them more common in consumer-grade systems where the cost-benefit of ECC is less critical. With its 2GB capacity and DDR3 technology, this Hynix UDIMM serves as a fundamental memory component for systems requiring basic memory performance. It is suitable for general computing tasks, office applications, and light multitasking. The specific part number HMT125U7BFR8C-G7T0-AA-C ensures that it meets the precise electrical and timing specifications required by compatible motherboards and processors.
