Currently, the need to upgrade RAM is becoming necessary, especially with the upgrade of application software, which requires a large amount of RAM. However, not everyone clearly understands the parameters of RAM from which to upgrade. So let’s go together GhienCongListen discover about RAM parameters in the article below.
Parameters of RAM to note
The parameters of RAM that you need to master
RAM generally has a lot of parameters that the manufacturer prescribes, however, for those of you who are looking to upgrade RAM or overclock, there are 5 factors that you must master.

What kind of RAM is it?
Currently on the market there are 3 popular types of RAM: DRAM, SRAM and finally SDRAM. You should consider what type of RAM your computer is using and what do you want to use it for now?
DRAM, or dynamic RAM, is a type of RAM that only needs to be charged after a few milliseconds. Used for temporary data storage purposes while running the application. Its data will be lost when the application is closed or shutdown. Currently, this is the widely used RAM standard for candidates with DDR3, DDR4 RAM, etc.

SRAM or Static RAM, is a type of RAM that stores data in batteries containing capacitors or transistors. It only needs to provide power, not charging like DRAM. Because it is faster, it is also more expensive than DRAM and is often used as a cache for CPUs.

SRAM vs DRAM
The last is SDRAM or DRAM dynamic synchronization. It is synchronized with the system bus so it has a very fast processing speed and almost no latency.
SDRAM
DDR technology
DDR technology or Double Data Rate. It is based on the above SDRAM type. It has the effect of transmitting 2 parallel data streams in each clock instead of 1 like SDR (Single Data Rate), so its data access speed is extremely fast.
DDR technology helps RAM access data quickly
Data transmission channel
Have you ever heard of Dual Chanel? That’s right, this is a parameter that represents whether you can run 2 RAM sticks in parallel or not.
The current RAM sticks have a width (Bandwidth) of 64bit. These channels are like roads, if you have 1 then of course you can only transmit 64 bits, but if 2 sticks of RAM work together, you can transfer twice as much at the same time.
Data transmission pulse rate
Pulse speed or RAM bus, This is probably the parameter that attracts the most attention if you choose RAM. It represents the data transfer rate of RAM. The higher it is, the faster the transmission speed will be.
One thing you should note is that this parameter provided by the manufacturer is the highest parameter that RAM can achieve, not that it automatically runs stably with such a clock. Pay attention.
Bandwidth
The last parameter in the parameters of RAM that you should know is bandwidth. Roughly, it is the read / write speed of RAM in one second. And calculated by the formula Bandwidth = (Bus Speed x Bus width) / 8. The higher the bandwidth, the faster the data read / write speed, you will see this clearly if you copy a file that weighs several Gb in a few seconds. .
Bandwidth is also one of the parameters of RAM you should pay attention to
