You might have already done some research on computer memory and seen the significance of RAM. It is not just the capacity of the RAM that is important, the speed and latency of the RAM is significant as well. It is very much possible for two RAM chips, made by two different manufacturers with different specification, to vary in speeds. To understand the differences, you will need to read up on the speed and latency aspects of computer memory.
Memory speed
A RAM chip comes in different speeds and you will often see it printed on the chip. You will see numbers such as DDR266, DDR400, and DDR800 and so on. All these numbers suggest different speeds. For example, DDR 266 means that the speed of the RAM is 2.1 gigabytes per second. The speed of the DDR400 chip is 3.2 gigabytes per second. The speed of the DDR800 is 6.4 gigabytes per second. These speeds are called bandwidth speeds. The processor on your computer will have a certain bandwidth speed and your RAM chip will ideally need to at least match that speed. If it is does not match, it will result in slow or less than optimal performance for the computer. Thus, it is not just the capacity of the RAM that is important. You will need to pay attention to its bandwidth speed as well.
Latency of the memory
This is a less important feature of the RAM that will decide the speed of the computer. Latency is the amount of time it takes for the RAM chip to respond to a request from the processor. Obviously, a RAM chip with lower latency will be faster as it will be able to respond to the processor quicker. However, most average users will not find latency of RAM to be a big issue. It is only users who use high tech 3D animations or advanced graphics software that will see a difference in computer speed that is affected by the latency of the computer memory chip.
Thus, when buying RAM or upgrading RAM, it will be important to consider the two aspects mentioned above as it can make a difference to the speed of the computer. The most optimal RAM is one that is compatible with your processor and you will need to find one that is the closest match to your processor's capabilities. Many users tend to focus on the capacity of the RAM and not its speed. We hope this article will help you avoid that mistake.
