Ram is an indispensable component of a computer, not only that it directly affects the speed of a computer.
On the blog, the Admin has a few very detailed articles about RAM already, if you want to learn more about RAM, please read through these articles first:
Return to the main content of the article today. So what should we pay attention to when installing, as well as choose to buy Ram for the computer to achieve the highest efficiency? Please also blog to share knowledge to learn more through the article below.
#first. Pay attention to Ram type, standard RAM
Currently, the most commonly used 2 types of Ram on the market are DDR3 and DDR4. The most basic difference in these two types of RAM is that the pin and the data transfer rate is calculated in Million Transfer Per Second (abbreviated as MT / s or Giga Transfers Per Second for short GT / s).
DDR4 has a data rate of about 2133-4266MT / s, while DDR3 has a data transfer rate of about 800-2133MT / s. Also, the pins of DDR4 and DDR3 are different, so it is impossible to use the same slot ..
#2. Parameters related to Bus Ram
Bus Ram is simply understood as the speed of data processing in 1 second of Ram, the higher the Bus, it also means the higher processing throughput. Can be calculated by formula Bandwidth = (Bus Speed x Bus Width) / 8.
Inside:
- Bandwidth: Also known as memory bandwidth, RAM data is readable in 1 second (MB / s).
- Bus Speed: The rate at which data is processed per second.
- Bus width: Is the width of the memory. The current types of DDR3, DDR4 RAM have a fixed Bus Width of 64.
For example you have a DDR4 – 2400 Ram, which means that the Ram has 2400MHz Bus with 19,200MB / s Bandwidth which is in 1s Ram can transport 19Gb of data.
Why is the number 19,200MB / s? Then you apply the above formula only: Bandwidth = (2400 x 64) / 8.
# 3. Should install one or more RAM sticks on the computer
If you have 2 sticks of RAM with the same capacity (generally identical) then it is advisable to install 2 or more RAM sticks.
When you install 2 or more RAM sticks, the transport data traffic will be doubled compared to when you use only one stick.
For example, RAM 8G DDR4 – 2400 by default it will transport 19Gb / s of data, but if you install 2 4G DDR4 – 2400 sticks the data throughput is doubled to 38Gb / s. This is the reason why it is always better to install 2 Ram (Dual RAM) at the same capacity.
Note is when you install 2 different RAM sticks, the computer only accepts the lowest bus of the 2 RAM sticks that you have attached to the computer. And each computer mainboard only supports a certain level of bus, even if it is installed higher, the machine will only receive at the maximum level given by the manufacturer.
# 4. Should I use Ram with a heatsink?
Usually, the Ram with heatsinks are Ram designed to operate at high intensity, usually for those who need OC Ram (Over clock RAM), those who work with high intensity and of course. is that the cost of this type of RAM is very expensive.
In my opinion, unless your finances are abundant, for the majority of us general users, investing in Ram with heat dissipation is not so necessary.
If you do heavy work such as continuous gaming, high quality video rendering, or 3D rendering, you should invest in bringing the highest performance to your Ram.
Below is the detailed structure of a RAM stick with a heat sink.
# 5. How much Ram is enough for the computer?
The eternal question of many people, if you are a universal user, 4G Ram is enough for you to surf the web and use light office tasks.
If you are a professional office worker, or use office tools, or work with multiple web browser tabs, you should have at least 8GB of RAM. Whatever you say, the applications and programs today are much heavier than before.
Also at a higher level, such as people playing games, streaming games, making graphics, editing movies, designing…. or if you work hard, you should equip at least 16GB of Ram for yourself, the maximum is fine, as long as you can afford the money, and of course your system must also support, similar like more ..
# 6. Epilogue
Yes, the above is basic knowledge of RAM and Important note when buying Ram, install Ram for the computer so that the most efficient.
