How to select the correct RAM for your computer.

-
When we think to upgrade the RAM of a PC, we have lots of questions in our minds. Which RAM is better and What type of RAM is compatible with our motherboard. Note that laptop memory and desktop memory are different in size and not interchangeable. Laptops use SODIMM RAM whereas desktops use DIMM RAM. We’ve highlighted four different factors that you need to know when picking memory for your system.
  • Are you using a desktop or laptop?
  • How Much RAM Do You Really Need?
  • How many RAM slots does your PC/laptops have?
  • What Type of RAM your PC/Laptops use DDR4 or DDR3 or DDR2?

RAM

RAM refers to Random Access Memory, and it is used for temporary storage by the CPU in a computer. Some characteristics of RAM include:
  • It is volatile memory i.e.contents are lost when power is switched off.
  • It is the fastest memory which means that the computer is not kept waiting for data to process
  • It is more expensive.
  • RAM is continuously overwritten and refreshed.
Motherboard

The motherboard is the circuit board on which the processor, memory modules, storage, and other components are located.

Each type of motherboard is designed to work with specific types of processors and memory, so they don't work with every processor and type of memory. However, hard drives are mostly universal and work with the majority of motherboards, regardless of the type or brand.

Memory Technology:

Each generation of memory technology has higher frequencies, lower voltage, and lower latencies than the previous generation. However, if your system was designed for DDR2 technology, it won’t be able to support DDR3 modules. Because both have different key notch locations and different pin configurations so they won't physically fit. So, motherboards are generally able to support only one type of memory technology. Use only the RAM type and speed specified by your motherboard's manufacturer.


How Much RAM Do You Really Need

It totally depends on what you are doing on your computer. 4 GB is found in regular desktops and office computers or those still running a 32-bit OS but it is not for gaming in 2021. Now question arise

Are you need a budget-friendly gaming computer?
8GB is a good start for now.

Are you need RAM for video editing/graphics design, etc.?
Going with at least 16GB (or more, depending on your budget) would be a wise decision.

With 8 GB of RAM, your PC will be running most games without any problem but 16 GB of RAM is sufficient for playing games and memory-intensive programs. You will never run out of RAM no matter what game you play. 32 GB might be a good idea if you want to make your build more future-proof or use any RAM-intensive software. your computer also running any memory-intensive programs in the background.64 GB  of RAM is for deep learning and high-end programming.


How to check details about your RAM 

You can check the number of RAM slots, form factor, speed, and type of RAM in the following ways.

On Window 8 and above, use the task manager. To open the task manager:
  • Press CRTL+SHIT+ESC keys to open the task manager. Or click the Windows button and type Task Manager in the search box
  • In Task Manager, click on the Performance tab.
  • Select the memory option left side of the Performance tab, and you can check the speed, type of RAM, the form factor (DIMM), and also how many RAM slots you have on the motherboard.


Window 7 does not provide any facility to check RAM details. So, You have to download and install the third-party app ‘CPU-Z’. CPU-Z is a freeware software from CPUID that provides in-depth information and performance about your computer processor, motherboard, memory, and graphics card. After install, click on the Memory tab to check the RAM size, type, and speed.





































 The next tab, SPD, shows more detailed information. One of the two RAM chips installed (in slot #1) is DDR4-2132 (1066 MHz) 8GB RAM by Micron Technology.

RAM and Types of RAM(Random Access Memory)

What is RAM? RAM is the hardware device where the data, operating system, and application programs are kept which are currently use, so they can be quickly accessed by the processor. RAM is the main memory of a computer system. A computer system is not working without RAM.  Characteristics of RAM 1) It is volatile memory i.e.contents are lost when power is switched off. 2) It is the fastest memory which means that the computer is not kept waiting for data to process 3) It is more expensive than secondary memory. 4) It is used to store temporary information. Function of RAM The main function of RAM is to provide  fast temporary storage  for data and programs, which includes both applications and the operating system along with hardware drivers. When you start a program on your system, the CPU fetches the program from the hard drive. Once your system fetches files, the system requires a workspace where this data temporarily store and execute. Here RAM works as a digital countertop to per

Computer Memory Unit

A computer memory unit is used to measure the amount of data that can be store in a storage unit. A group of binary digits that is 0's and 1's is used to store and process the data because the computer only understands the machine language or binary language. Types of a Memory storage unit The memory units of the data in the storage systems are classified into the below different types Bit:  A bit stands for binary digit. A bit is a one or a zero, on or off, which is how all computer information is stored. A bit is the smallest memory unit to measure data stored in main memory and storage devices. Nibble:  Nibble can be defined as the collection of four bits. It is sometimes called Nybble’ or ‘Nyble’ or ‘hex digit’. Byte: It is the fundamental unit to measure data. A group of 8 bits is called byte. Thus a byte can represent 2*8 or 256 values. This storage capacity is expressed in terms of Bytes. This is the commonly used unit terminology, as it comes with the prefixes for the m

Primary Memory

Primary Memory is the main memory of the computer system. It is also called internal memory . Without a primary memory computer system does not work. It is directly accessed by the CPU(Central Processing Unit) . The primary memory is volatile in nature which means data does not exist if it is not saved when a power failure occurs. Characteristics of Primary Memory 1) It is known as the main memory or internal memory. 2)  It directly communicates with the CPU of the computer. 3) It is faster as compared to secondary memory. 4) It is very costly as compared to secondary memory. 5) A computer cannot run without the primary memory 6) It is made by semiconductor devices so its called semiconductor memories 7) It is volatile in nature i.e.contents are lost when power is switched off Types of Primary Memory Primary Memory is Classify in the following way: 1) RAM(Random Access Memory) 2) ROM(Read-only Memory) 3) Cache RAM(Random Access Memory) RAM is the main memory. RAM is the hardware that i
