Benefits of ECC (Error Correction Code) in Server Memory

Data Integrity

In server environments, data integrity is of paramount importance. The ECC feature in the Samsung M393A2K43CB2-CTD enables the detection and correction of errors in real time, preventing data corruption. This is especially critical in applications where even a minor error can have significant consequences.

System Stability

Error correction contributes to overall system stability. By identifying and rectifying errors before they impact system operation, ECC ensures that servers can maintain consistent and reliable performance. This is crucial in environments where uptime is a critical metric.

Long-Term Reliability

The ECC capability enhances the long-term reliability of server memory. Over time, memory modules may experience bit errors due to various factors, including cosmic rays and electromagnetic interference. ECC mitigates the impact of these errors, extending the lifespan of the memory module and reducing the likelihood of unexpected failures.

Memory Capacity

The memory module has a capacity of 16GB, which means it can store up to 16 gigabytes of data. This is a significant amount of memory, especially for servers that need to store large amounts of data and run multiple applications simultaneously. The 16GB capacity of the module ensures that servers can run efficiently without experiencing performance issues caused by a lack of memory.

Clock Speed

The M393A2K43CB2-CTD memory module operates at a clock speed of 2666MHz. Clock speed refers to the rate at which the module can access and transfer data. A higher clock speed means that the module can access and transfer data more quickly, resulting in improved system performance. The 2666MHz clock speed of the module ensures that servers can process data quickly, minimizing any delays or latency.

Memory Type

The M393A2K43CB2-CTD memory module is a DDR4 SDRAM. DDR4 stands for Double Data Rate 4th Generation Synchronous Dynamic Random-Access Memory.
