When it comes to computers, we unconsciously think that the number of CPU, RAM and graphics should be large enough to have that system more efficient and powerful. But is it really?
In this article, we want to talk specifically about RAM in computers and see if we need to just pay attention to memory or there’s another factor that matters.
One of the main and key factors in choosing RAM for a computer is its speed. But what exactly is the speed of RAM, and more importantly, how do you consider this feature when buying a computer system along with other features?
What is the meaning of different classifications of RAM?
The speed of RAM in short is the amount of data transfer at a specified time. The larger the number, the more RAM it can import and transmit data. The formula for displaying speeds in different versions of DDR is very small.
This number does not indicate the clock speed (such as what we have on the processors) and integrates a set of hardware specifications together and shows the overall result. But this factor does not change the form of the problem; the faster it is, the faster it is.
So everything is simple. The situation becomes more complicated when a number of other terminology and classifications are inserted into the RAM. In almost all cases, the speed of RAM is measured using the DDR statement. You may also see standards like PC2 / PC3 / PC4. These phrases are usually written after the hardware-specific standard; the DDR3 1600 RAM is the same as the PC3 12800, and the DDR4 2400 RAM is the same as the 19200 PC4.
The reason for such dual standards returns to the bit structure and byte in the data unit – a byte is equal to 8 bits. So if the first number is DDR 1600, measured at million bytes per second, the second number will be PC3 12800, which is a unit of million bits per second. We’ll get 12800 if we divide it by 8 to 1600. So we see a fixed case with two different standards.
To avoid confusion, it’s best to take the same DDR2 / 3/4 benchmark.
What does timeline mean?
In addition to speed classification, there are other numbers on the RAM memory that are related to its timing. These numbers are similar to 5-5-5-15 or 8-8-8-24. This category is dedicated to advanced and specialized topics in the field of science, which we will only mention in plain language in this article and will not enter into details. So, first of all, in brief, know the set of numbers we call Latency.
Latency indicates how fast Ram can access its hardware. The lower the speed, the better, and shows that access to information is faster.
Naturally, the higher the latency, the higher your RAM will be. This factor, coupled with the clock speed of RAM, can be manipulated, and we sometimes hear that users are doing this.
The difference in the Latency of the various models is so insignificant that it only matters at the level of large organizations with massive servers. So you do not have to be obsessed with as a normal user of a simple computer.
How will these effects affect your computer?
Honestly, it does not have much effect. While the factors listed will increase the speed of your system, but this increase will not be so much that you feel something and get pleasure from the extra cost you’ve set.
Perhaps the RAM faster in a number of specialized benchmarks, the system put in front of you, but when it comes to high performance for ordinary use and is the only effective and tangible, the Rome more will be.
So if you decide to buy RAM and stay tuned between two 8GB DDR4 models at 3200s or 16GB DDR4 at 2400 rpm, you’ll probably go for the second option. Do not think about raising the clock, because it does not cost you much effort.
This is true for gaming too. If your system has a separate graphics card, the games will depend on the memory card of the graphics card (called GDDR ).
Note that the memory card is an inseparable part and can not be upgraded after purchase. So in this case, when buying, note that you will buy the most memory, not the fastest.
Graphics cards have their own memory, so when playing games, the RAM speed of the system does not have much impact.
The high speed of RAM is very important in systems that have an on-board graphics and improves visual effects. The reason is that the graphics card does not have a separate memory itself and uses the RAM system for graphics processing. Other than this, it’s not important for ordinary users that the speed of RAM is high or low.
Difference between DDR2, DDR3 and DDR4
RAM has different generations. The faster the generation of a new memory, the faster the access to information.
The DDR standard, which stands for Double Data Rate, means “Dual Speed Data”, introduced in 2000 instead of the standard Single Data Rate, and now we’ve got DDR4 version after 17 years. The DDR3 standard introduced in 2007 is already in use and is being used in older systems.
As we go forward, these standards are progressing and delivering higher speeds for RAM. But the important point is that no standard has the capability to match the higher or lower standards. For example, if your laptop or motherboard has a DDR3 standard, you can not install DDR2 or DDR4 RAM.
But it’s not about the speeds. You can use a RAM at any rate below the permissible limit of the motherboard without any problems. For example, in a DDR4 motherboard that supports up to 3600 MHz, you can also install DDR4 2400 MHz RAM.
When installing different hardware, if you find that there are different categories similar to the example above, there is no need to worry. Your motherboard is so smart that it can synchronize between different parts.
