Description
Key Features and Specifications
The SNP4JMGMC/64VXR Dell 64GB 2666Mhz PC4-21300 DDR4 SDRAM is a high-performance memory module that is specifically designed for use in Dell servers. Here are some of the key features and specifications of this memory module:
- Capacity: 64GB, which provides a large amount of memory to improve system performance.
- Speed: 2666Mhz, which refers to the number of data transfers that can occur per second. A higher speed means faster data access and better system performance.
- Technology: DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random Access Memory), the latest technology of RAM that provides faster data transfer rate and low power consumption.
- Error Correction: ECC (Error Correcting Code) which means it can detect and correct errors that may occur during data transfer, improving the overall reliability of the system.
- JEDEC standard: PC4-21300, indicating that the memory conforms to the JEDEC standard for DDR4 memory with a transfer rate of 21,300MB/s.
- Pin Design: 288-pin design, ensuring compatibility with Dell servers that use this type of memory.
- Timing: CL19, which refers to the timing of the memory. A lower number indicates faster timings and better performance.
- Form Factor: 288-pin DIMM (Dual In-line Memory Module) which is a standard form factor of memory modules used in most of the servers.
- Voltage: 1.2V, which is the voltage required to power the memory module.
Error Correction and Data Integrity
The SNP4JMGMC/64VXR Dell 64GB 2666Mhz PC4-21300 DDR4 SDRAM memory module features Error Correction Code (ECC) technology, which helps to ensure data integrity and reliability. ECC memory is commonly used in server and high-performance computing environments where data accuracy and integrity are critical.
ECC memory uses a system of error detection and correction codes to detect and correct errors that may occur during data transfer. This is done by adding extra bits of information, called parity bits, to the data that is stored in the memory. When data is read from the memory, the parity bits are used to check for errors. If an error is detected, the ECC algorithm can then correct the error before the data is passed on to the system.
The use of ECC memory improves the overall reliability of the system by detecting and correcting errors that would otherwise go unnoticed. This is particularly important in a server environment where data loss or corruption could have serious consequences. ECC memory can also help to reduce the likelihood of system crashes and data corruption, as well as improve the overall performance of the server.
In addition to ECC, the SNP4JMGMC/64VXR Dell 64GB 2666Mhz PC4-21300 DDR4 SDRAM memory module also features parity protection, which is another feature that helps to improve data integrity. Parity protection is a method of detecting errors that occur during data transfer by adding an extra bit of information to the data. If a parity error is detected, the system can then take appropriate action to correct the error and prevent data loss.
Pin Configuration and Form Factor
The SNP4JMGMC/64VXR Dell 64GB 2666Mhz PC4-21300 DDR4 SDRAM memory module features a 288-pin configuration and a DIMM (Dual In-line Memory Module) form factor.
The pin configuration refers to the number of pins on the memory module that are used to connect it to the motherboard. The 288-pin configuration is the standard for DDR4 memory, and is the same number of pins as used in DDR3 memory. This allows the memory module to be compatible with a wide range of systems that use DDR4 memory.
The form factor of a memory module refers to its physical size and shape. DIMM is a standard form factor for memory modules that is used in most of the servers. DIMM memory modules are typically longer and wider than other types of memory, such as SO-DIMM (Small Outline Dual In-line Memory Module) which is commonly used in laptops.
The DIMM form factor allows for a larger number of memory chips to be installed on the module, resulting in higher capacity memory modules. The 288-pin design of the SNP4JMGMC/64VXR Dell 64GB 2666Mhz PC4-21300 DDR4 SDRAM memory module ensures compatibility with Dell servers that use this type of memory.
