Overview of the 840759-691 HPE 64 GB Pc4-21300 2666 MHz Memory Module

The 840759-691 HPE 64 GB Pc4-21300 2666 MHz Memory Module is a high-performance memory module designed for use in servers, workstations, and high-end desktop computers. With a capacity of 64 GB, it can store 64 billion bytes of data, providing ample memory for running multiple applications and handling large amounts of data.

The memory module has a speed of 2666 MHz, which refers to the number of data transfer cycles per second. A higher speed means that the memory module can transfer data more quickly, which can result in improved system performance. The 2666 MHz speed of the 840759-691 HPE memory module is faster than some other DDR4 memory modules that may have speeds of 2400 MHz or 2133 MHz.

This memory module also supports Pc4-21300, which is a memory standard that provides faster data transfer speeds, improved power efficiency and higher memory density. This makes it suitable for demanding applications such as virtualization, big data analytics, and high-performance computing.

The 840759-691 HPE 64 GB Pc4-21300 2666 MHz Memory Module is designed to work with the HPE ProLiant and Synergy servers, as well as other HPE and non-HPE servers and workstations that are compatible with DDR4 memory. It is a registered DIMM, which means that it has a register chip on the module that buffers the address and command signals, allowing for greater scalability in systems using more than one DIMM per memory channel. It also supports Error Correction Code (ECC) which is a method for detecting and correcting errors in data.

Comparison with other DDR4 Memory Modules

When comparing the 840759-691 HPE 64 GB Pc4-21300 2666 MHz Memory Module with other DDR4 memory modules, some key points to consider include:

  • Capacity: The 840759-691 has a capacity of 64 GB, which is larger than many other DDR4 memory modules that are available on the market. This makes it a good choice for servers and workstations that require a large amount of memory.
  • Speed: The 840759-691 has a speed of 2666 MHz, which is relatively fast compared to other DDR4 memory modules. The higher the speed of the memory, the faster data can be accessed, which can improve the overall performance of the system.
  • ECC Support: The 840759-691 has ECC support. ECC memory is able to detect and correct errors in data, which can help prevent system crashes and data corruption.
  • Registered or Unbuffered: The 840759-691 is a registered DIMM. Registered DIMMs have a register chip on the module that buffers the address and command signals, allowing for greater scalability in systems using more than one DIMM per memory channel.
  • CAS Latency: The 840759-691 has a CAS Latency of CL19, which is relatively low. CAS Latency is the time it takes for the memory to access a particular location in the memory array. Lower CAS Latency means faster memory access, which can improve system performance.
  • Voltage: The 840759-691 requires a voltage of 1.2V, which is a standard voltage for DDR4 memory modules.
  • Form Factor: The 840759-691 has a form factor of 288-pin DIMM, which is the standard form factor for DDR4 memory modules.
  • Brand Compatibility: The 840759-691 is designed to work with HPE ProLiant and Synergy servers, as well as other HPE and non-HPE servers and workstations that are compatible with DDR4 memory.
  • Warranty: The 840759-691 comes with a 3-year warranty, which is longer than the warranty for many other DDR4 memory modules on the market.

What is the DDR4 Memory Standard?

The Double Data Rate Fourth Generation Synchronous Dynamic Random-Access Memory, otherwise known as The DDR4 SDRAM, is the latest high-efficiency memory module with 288 pins, released to the public in the second quarter of 2014. The PC4-21300 or DDR4-21300 comes with a mega transfer speed of 21300Mg/s. It flaunts cutting-edge performance and is highly compatible with AMD Ryzen processors and DDR-enabled Intel motherboards.

Memory Clock Speed

The clock speed is the measure of the number of cycles the system's CPU executes per second. In the case of the PC4 21300 memory module, it is 21,300MB/s. You'd want to check what works for your computer before making any buying decision.

Cycle Time

The time between the beginning of one random access memory (RAM) access to when the subsequent access begins is the Cycle time. This time is usually measured in nanoseconds. The PC4-21300 has a cycle time of 19ns.

I/O bus clock

The I/O bus clock of the PC4-21300 is 10650MHz. I/O bus clock is always half of the bus data rate.

Things to consider before buying a Memory module

The computer's RAM remains a crucial component for cutting-edge performance and efficient computing. Thus, buying one for your computer shouldn't be taken with levity. Here are a few things to consider when purchasing a RAM.

  • Interface

DDR4 memory is not compatible with a motherboard designed for DDR3 memory, and the same goes for other modules. Hence, you must ensure the RAM you buy is the specific type your motherboard needs.

  • Amount of RAM

As mentioned earlier, as far as size goes, allhdd.com has the most comprehensive collection of PC4-21300 modules. If your machine handles many programs simultaneously, you may want to increase its RAM for better performance.

  • Frequency

DDR4 RAM begins from 2133 MHz and goes all the way up to a stunning 4266 MHz. You want to be sure you purchase RAM with a frequency that is compatible with your computer. Getting this wrong could prove fatal as you can harm your computer as well as the incompatible RAM.
