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.
