The 726718-S21 is an 8GB DDR4 SDRAM memory module that has been specifically designed and manufactured for use in servers. It is a high-quality memory module that is made by Hewlett-Packard Enterprise (HPE), a well-known brand in the world of IT infrastructure. This module is designed to meet the high-performance demands of modern servers and is ideal for use in data centers, web hosting environments, and other enterprise applications.
DDR4 SDRAMDDR4 SDRAM is the fourth generation of Double Data Rate (DDR) Synchronous Dynamic Random Access Memory (SDRAM) technology. It is an improvement over the previous DDR3 SDRAM, offering faster speeds, higher densities, and lower power consumption. DDR4 SDRAM operates at a higher frequency than DDR3 SDRAM, with data transfer rates ranging from 2133 MT/s to 4266 MT/s.
Registered DIMM (RDIMM)The 726718-S21 memory module is a Registered DIMM (RDIMM). RDIMMs are designed to reduce the electrical load on the memory bus by using a register or buffer between the memory controller and the DRAM chips. This allows more memory modules to be installed on a server without causing signal integrity issues. RDIMMs also provide error correction code (ECC) functionality, which can detect and correct single-bit errors.
Single Rank X4 DDR4 ECCThe 726718-S21 memory module is a Single Rank X4 DDR4 ECC module. This means that it has a single rank and uses four memory chips per rank. The ECC functionality provides an additional layer of data integrity by detecting and correcting errors in memory. This is particularly important in server environments where data integrity is critical.
2133MHz PC4-17000 RAM & CAS LatencyThe 726718-S21 memory module operates at a frequency of 2133MHz and has a PC4-17000 rating. The PC4-17000 rating indicates the peak transfer rate of the memory module. This means that the module can transfer data at a rate of 17GB/s, which is faster than the previous DDR3 SDRAM technology.
CL15 The 726718-S21 memory module has a CAS latency of 15, which is abbreviated as CL15. CAS latency is the time delay between when the memory controller requests data from the memory module and when the data is available. A lower CAS latency indicates better performance as it reduces the time delay.
1.2V The 726718-S21 memory module operates at a voltage of 1.2V. This is a lower voltage than the previous DDR3 SDRAM technology, which operated at 1.5V. The lower voltage helps to reduce power consumption, which is important in server environments where power usage can be a significant cost.
288-pin The 726718-S21 memory module has 288 pins, which is the standard number of pins for DDR4 SDRAM memory modules. The pins connect the module to the memory slot on the motherboard of the server.
In summary, the 726718-S21 memory module is a high-quality DDR4 SDRAM module that has been designed and manufactured by HPE for use in servers. It is a Registered DIMM that uses ECC functionality to provide an additional layer of data integrity. It operates at a frequency of 2133MHz with a PC4-17000 rating and has a CAS latency of 15. The module operates at a voltage of 1.2V and has 288 pins. It is ideal for use in data centers, web hosting environments, and other enterprise applications where performance and data integrity are critical.
