Ram is a hardware device that greatly affects the performance and speed of your computer. Your computer is short of RAM and you are planning to upgrade more to meet your needs?

Yes! This techtipsnreview article will share experience upgrading RAM for laptop computers and the most detailed and easy to understand PC.

#first. What is computer RAM?

RAM (Random Access Memory) is random access memory because it has the property: read or write execution time for each memory cell is the same, no matter where it is in memory.

Each RAM cell has an address. Typically, each cell is one byte (8 bits); however, the system can read out or write to multiple bytes (2, 4, 8 bytes).

The larger the RAM capacity, the better your system is, but it depends a lot on the version of the operating system you are using (Windows 32bit or 64bit). If you are using 32bit version, it only supports up to 3.4GB only.

RAM is the place where the operating system or application program stores data so that the CPU can quickly access it. Increasing RAM capacity means reducing the number of times the CPU has to fetch data from the hard drive (HDD), a process that takes longer than reading data directly from RAM, RAM access time is measured in nanoseconds in then HDD access time is measured in milliseconds).

#2. Why does the computer need RAM?

As you all know, the hard drive communicates with the CPU through the IDE port, so the speed will be slower than the connection port of RAM mounted directly on the motherboard (motherboard).

In addition, the access to the hard drive will also take a lot more time because it uses sequential and RAM uses random access type (Random).


# 3. How do you know if your computer is running low on RAM?

Once the computer lacks RAM, it will cause freeze, jerky, and lag, which is very uncomfortable to use. To know exactly whether the computer lacks ram or not, press the key combination Ctrl + Alt + Del or Ctrl + Shift + ESC to enter Task Manager.

As shown in the image below, you will notice the section Memory. My computer has a capacity of 4GB RAM and is using 3.5 GB that is using up 90% RAM (because I have a lot of programs running).

If this number goes up to 3.8 or 3.9, then surely your computer will be frozen ? and if you want to use it smoothly, you have to turn off running applications or one more way that is RAM upgrade.


# 4. Steps to upgrade RAM

Using CPU-Z software, if you do not have and do not know how to use it, please see the detailed instructions in this article.

+ Step 1: First you need to see how many RAM slots your computer has. Usually modern computers now support more RAM slots to support the upgrade and use more RAM.

+ Step 2: What type of RAM are you using? (SDR, DDR, DDR 2, DDR 3….). To upgrade, you need to buy a corresponding type of RAM, and each type of ram has a different number of pins for us to easily distinguish and not be confused.

Therefore, you cannot plug DDR type into DDR2 or DDR3 slots and cannot plug DDR2 type into DDR and DDR3 slots, nor can DDR3 RAM type into DDR or DDR2 slots which means each slot to RAM plugs can only be inserted in a single type of memory to be inserted into.

  • DDR: Models with Pentium-M CPUs.
  • DDR2: The models use CPU Intel Core Duo, Core 2 Duo ..
  • DDR3: Intel Core 2 Duo, Core i series

+ Step 3: How much RAM is it currently? If you use a 32-bit operating system, you should only use 3GB of ram.

If you want to use more, you install the 64-bit version to use it. To see how much RAM you have, right-click Computer => Properties => look down at Memory or Installed Memory Let’s see how much capacity is.

1 / Select the appropriate Bus Ram

+ Step 4: When we attach the RAM sticks to the slot, the RAM sticks you should choose the same bus together.

Otherwise, the bus will not make the most of the RAM and will waste money when upgrading. When you use 2 Rams on a computer and different Buses, the computer only uses the smaller Bus.

Understanding more about BUS RAM: The RAM bus is the operating frequency of the RAM (in MHz). The larger the RAM bus, the better the system speed, the shorter the data transfer time to the CPU and vice versa.

2 / Ram bus calculation method (266/333/400/533/800/1333/1600/1800/2000 …)

Open the CPU Z software and switch to Tab Menory

Here you get DRAM Frequency x 2 => will output the Bus number of DDR, DDR2, DDR3. As for SDRAM, the DRAM Frequency parameter remains the same = the BUS number.

The example is shown below: my current RAM is DDR3 and Bus 1600


OK, now you have all the elements to buy a ram for your current ram.

Or if you have removed the computer Ram then you can see the parameters directly on the Ram, for example, as shown below:


Some RAM also write more parameters as Bandwidth always on RAM, so you can calculate RAM bus = Bandwidth / 8


3 / Which brand of RAM should be used?

Some brands that you can look for are: Kingston, Transcend, Sandisk, Samsung, …
