I just received a request to "Explain why some operating system show less amount of usable RAM than Actual Memory in the system". So i will clear all your doubts today. So Lets get back to business without wasting much time.
First of all i would like to introduce you to RAM, RAM stands for "Random Access Memory" it falls under the category of Primary Memory and is actually main part for why we are able to run applications, because it stores the data and Machine codes that are currently being used on the system. ROM is another member of primary memory and BIOS(Basic Input/Output System) is generally stored in ROM which checks all the hardware and Operating system when the computer starts as soon as the computer successfully reaches the welcoming screen where all the data is being loaded on RAM for further processes and OS takes over the Command over the System as soon as BIOS finishes its task.
RAM contains multiplexing(multiplexer is a device which selects one of the several incoming analog or digital signals and sends it through a single line) and demultiplexing circuitry (several incoming analog or digital signals are combined to form one signal). As RAM is a form of volatile memory it stores data till the time it receives electrical power i.e. it deletes all the data stored in it when system shuts down.
Nowadays as i said in my previous posts that now many manufacturers have started embedding Graphics Enhancing technologies in Motherboards or Processors. Since Dedicated Graphic cards that you buy as add on part have their own Video memory they don't reserve any part of RAM to run the function But in case of Integrated Graphic cards don't have any Video memory of its own so they uses some percentage of main RAM to carry out functions.
I bet you don't know that 32-bit OS can only use maximum memory of 4 GB(RAM) if you install 4 GB 32-bit operating system will start to show usable memory of it under 4 GB. Some 32-bit Operating Systems have above 4 GB too i will explain that in upcoming posts.
64-bit has a advantage over 32-bit Operating Systems as they can use memory above 4 GB as well. BUT Instead Windows 7 64-bit most often is unable to identify the actual amount of memory installed in the system. You can solve this problem manually instead.
The steps to be followed are-
Thank you for reading.
Cheers :)

- Now, the question is why some operating systems show less usable RAM than actual memory in the system.

- YOUR 32-BIT OPERATING SYSTEM HAS LOW LIMIT OF MEMORY-
I bet you don't know that 32-bit OS can only use maximum memory of 4 GB(RAM) if you install 4 GB 32-bit operating system will start to show usable memory of it under 4 GB. Some 32-bit Operating Systems have above 4 GB too i will explain that in upcoming posts.
- INSTEAD YOU CAN TAKE 64-BIT ADVANTAGE TO USE IF YOU HAVE MEMORY OVER 4 GB-
64-bit has a advantage over 32-bit Operating Systems as they can use memory above 4 GB as well. BUT Instead Windows 7 64-bit most often is unable to identify the actual amount of memory installed in the system. You can solve this problem manually instead.
The steps to be followed are-
- Click on Start then go to Run.
- Type "msconfig" in the text field that appears in Run.
- Under BOOT section click advanced option.
- On top right of the dialog appeared you will see a section of Maximum Memory select it if initially it is unselected and you will se the maximum amount of memory in your System.
- Then click OK and restart you computer. Since i am assuming that you don't have any hardware related issue then system will now the usable memory will be max. in your system leaving the Reserved memory for hardware. If any further issue persist feel free to contact me or leave comments.
Thank you for reading.
Cheers :)
