Product Description
The Samsung M391A1K43BB2-CTDQY is an 8GB DDR4-2666 ECC UDIMM memory module designed to provide reliable system memory performance. It is typically used in servers and workstations where data integrity and stability are critical. This module supports error-correcting code (ECC) which helps detect and correct common types of data corruption, making it suitable for systems requiring enhanced memory reliability. Key Features 8GB capacity DDR4 memory Operating speed of 2666 MT/s CAS latency of 19 (CL19) ECC support for error detection and correction Unbuffered DIMM (UDIMM) form factor Its balance of capacity and speed alongside ECC functionality makes it a practical choice for enterprise environments that demand memory stability. The unbuffered design allows usage in compatible systems requiring standard UDIMM modules without registered or buffered memory.

Use Cases
This memory module is generally deployed in server or workstation environments where reliability and data integrity are priorities. It suits IT infrastructures that utilize unbuffered ECC memory for error detection and correction during operations. How It's Used: Installed in servers requiring 8GB DDR4-2666 ECC UDIMM memory Used in workstations handling critical applications needing error correction Deployed in data centers focusing on system stability Employed in IT environments that support unbuffered ECC memory modules Suitable for systems designed for DDR4 memory at 2666 MT/s speed The module serves to maintain data accuracy and system uptime by correcting memory errors on the fly. It plays a key role in systems where minimizing data corruption and preventing crashes are essential to operational integrity.

FAQ's
What does ECC mean in this memory module? ECC stands for error-correcting code, a feature that detects and corrects common memory errors to improve data integrity in systems. Is this module compatible with all DDR4 motherboards? This module fits motherboards supporting DDR4-2666 UDIMM memory with ECC support; compatibility depends on the motherboard's specifications. What does CL19 indicate? CL19 refers to the CAS latency, meaning the delay time between memory request and data availability is 19 clock cycles for this module. Can this memory be used in non-ECC systems? This is an ECC unbuffered DIMM; it may not function correctly in systems that do not support ECC memory modules. Does this module support registered or buffered memory? No, this module is an unbuffered DIMM (UDIMM) and does not support registered or buffered memory configurations. What type of workloads benefit from this memory? Workloads requiring data accuracy and error correction, such as servers and workstations running critical applications, benefit from this memory.
