What does "PC4" indicate in RAM specifications?

The designation "PC4" in RAM specifications is indeed related to DDR4 memory and indicates the memory bandwidth rated in megabytes per second. "PC" stands for "Pentium/PC" and is followed by a number that represents the type of DDR memory and its corresponding bandwidth. For DDR4 RAM, PC4 ratings imply that the memory operates at speeds of approximately 17,000 MB/s (or 17000 MB/s).

This classification system helps in identifying the performance level of the RAM, as it directly correlates with the effective data transfer rates of memory modules. Understanding this helps in selecting the right RAM that can maximize the potential of a computer system, particularly when considering build specifications or upgrades. The PC4 designation is essential for ensuring compatibility with motherboards that support DDR4 and optimizing performance according to specific computing needs.
