What is memory speed in RAM

Memory or RAM is a fundamental component of any technological device because it functions as the main memory of the system and serves to store previously solved operations and instructions that its processor can access to retrieve them when needed. In this way, the processor is prevented from having to repeat heavy tasks and the workload is optimized.

Why is memory important?

The results and instructions that RAM memory can store will depend not only on the total amount we load, but also on the characteristics of the program or application we use. In general, the more RAM we have, the more resolved operations and instructions we can store in it, and the better the performance.

RAM memory is filled and emptied depending on what we do on our computer. So, when we run a game, it is filled with important data and instructions from that particular game, and when we close the game, it automatically eliminates all that data and instructions, leaving it free to perform other tasks. Therefore, it is a type of memory that works in real time, automatically adapts to the work we do, and is also temporary, that is, it is completely emptied when we turn off the computer.

What is memory speed?

The performance of this component is determined by its capacity and speed. Having a larger amount of RAM will not only allow more applications, programs and web browser tabs to be open, but will also determine what types of applications we can run and what we can do. This is why it is such an important component, because it not only affects performance but can also limit the possibilities of any device.

For example, if we have a very limited amount of RAM memory, it will need to be partially or completely emptied and refilled at a certain frequency to adapt to the demands of the application or program in question, which will negatively affect performance. If we do not have the amount of memory required by an application or program, it will most likely not run or run with serious problems.

Memory speed is determined by the total bandwidth achieved by RAM memory, and this is affected by the operating frequency and the width of the bus. Having faster RAM with a more limited bus can deliver a much worse result than having slower memory with a larger bus. Currently optimal in consumer equipment is a 128-bit bus, which we will achieve by installing two memory modules in alternative areas on the motherboard to enable dual channel.

Greater bandwidth allows communication between RAM and other components, such as the processor, to occur faster and be completed in less time. In some configurations, this memory is also used by the graphics core, and in these cases bandwidth will have a big impact on its performance as the GPU will need to access heavier data and instructions.

RAM memory can be soldered to the board or in the form of removable modules. The second option is the most used in the PC world and allows us to upgrade the component in question simply and safely. Currently the most used memory types are LPDDR4 and LPDDR5, with a particular focus on the notebook sector and mobile devices, with Double Data Rate in the DDR4 and DDR5 standards.
