Product Description
The SK Hynix HMT451U7DFR8A-PB is a 4GB DDR3-1600 memory module engineered with ECC (Error-Correcting Code) to detect and correct data corruption. This UDIMM is typically installed in desktop systems that require enhanced data reliability during operation. It suits environments where memory error correction is necessary to maintain system stability, such as workstations or entry-level servers. Key Features 4GB capacity DDR3 SDRAM 1600 MHz clock speed CAS latency (CL) 11 timing ECC support for error detection and correction Unbuffered DIMM design for desktop platforms This memory module provides essential error correction capabilities combined with standard DDR3 performance, helping to reduce system crashes caused by data errors. It is commonly employed in systems where stability is prioritized over advanced buffering features.

Use Cases
This memory module is commonly used in desktop workstations and entry-level servers requiring ECC capabilities. It is suited to environments where data accuracy and system reliability are important, such as business desktops and small-scale computing setups. How It's Used: Installed in desktop PCs to expand memory capacity with ECC protection Used in entry-level servers for enhanced memory error correction Employed in workstations running data-sensitive applications Deployed in environments needing standard unbuffered DIMM modules Integrated into systems requiring DDR3-1600 MHz memory speed The HMT451U7DFR8A-PB serves as a reliable memory upgrade option that balances DDR3 performance with error correction. It helps maintain system stability where ECC is a prerequisite, without the complexity of registered or buffered memory modules.

FAQ's
What type of memory is the HMT451U7DFR8A-PB? It is a 4GB DDR3-1600 MHz ECC unbuffered DIMM designed for desktop systems. Does this module support error correction? Yes, the module supports ECC, which detects and corrects single-bit memory errors. Is this memory compatible with server systems? The HMT451U7DFR8A-PB is primarily intended for desktops and entry-level servers supporting ECC UDIMM memory. What does CL11 latency indicate? CL11 refers to the CAS latency timing, representing the delay between memory request and data availability. Can this module be used in non-ECC systems? It requires a system motherboard that supports ECC UDIMM; otherwise, it may not function properly. Is this a registered or buffered memory module? No, this module is unbuffered, intended for standard desktop memory slots.
