The operating voltage of the 04JMGM memory module is 1.2V, which is lower than the voltage used by previous generations of memory, resulting in lower power consumption and heat generation. It operates at a clock speed of 2666MHz (PC4-21300) and has a latency of CL19.

Understanding DDR4 SDRAM Memory

DDR4 SDRAM (Double Data Rate Fourth Generation Synchronous Dynamic Random Access Memory) is the latest and most advanced type of memory used in modern computing systems. It offers several advantages over its predecessors, including higher performance, increased bandwidth, and improved power efficiency.

One of the main advantages of DDR4 SDRAM memory is its high bandwidth, which allows for faster data transfer rates between the memory and the CPU. This results in faster overall system performance and improved multitasking capabilities. DDR4 memory typically operates at speeds of 2133MHz to 4800MHz, with higher speeds available in overclocked configurations.

Another significant advantage of DDR4 memory is its increased power efficiency. DDR4 memory modules operate at lower voltages than DDR3, resulting in lower power consumption and reduced heat generation. This makes DDR4 memory an ideal choice for use in energy-efficient systems and portable devices.

DDR4 memory also includes several new features, such as the ability to detect and correct errors in real-time using ECC (Error Correction Code) technology. This helps to ensure data integrity and system stability, making DDR4 memory ideal for use in high-reliability systems.

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, 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.
