8GB DDR4 2666 RDIMM server memory

Ultra-fast speed, high reliability and low energy consumption. 
High-performance storage supports faster and more powerful solutions. With wider bandwidth, higher reliability, and lower energy consumption, DDR4 provides an excellent experience. 
Significant performance improvement. 
-significant increase in bandwidth up to 3200 Mbps. 
DDR4 can transfer more data at excellent speed, providing four groups of repositories (a total of 16 repositories) to reduce interlaced latency, as well as 3200 Mbps bandwidth and 1TB/s system memory, so it can handle large workloads more quickly and easily. 

* Internal testing using DDR4 and DDR3. 

Low energy consumption, high energy efficiency. 
-Advanced technology. 
-reduce the number of cores and power / power outages. 
With Samsung's advanced 1x nano-process technology, DDR4 can improve performance and reduce total cost of ownership while reducing energy consumption. The 1.2V POD (low operating voltage and pseudo-drain open circuit) interface achieves lower power consumption, with a 25% reduction in energy consumption. 

* Internal testing using DDR4 and DDR3. 

Significant improvement in reliability. 
-secure CRC transport. 
-use parity bits to prevent errors. 
As the data center handles more and more traffic, system reliability becomes more and more important. DDR4's advanced features ensure superior data transmission, for example, write cyclic redundancy check (Write CRC) to help identify multiple failures. The parity check for the command (CMD) / address (ADD) path can prevent system failure.
