System memory in Windows Vista is Less than Expected with 4 GB of RAM

If your computer has 4 gigabytes of random access memory installed, then the system memory is reported in the system information dialog box in windows vista report less memory then you expect. If the system information dialog box may report 3120 megabytes of system memory on a computer that has 4 GB of memory installed (4096 MB). If you want to access the system information dialog box, then do it in this way.

At first click on the start button, open search box and type system in the search box and then click system under programs. Now double click on the system in control panel and now click start, right click computer and then click properties. Finally click show more details in the windows vista welcome center window. Windows Vista can change to the way components of the user interface report memory.

Cause of these problems

These problems basically arise because of the address space, which is limited to 4GB in a 32-bit hardware environment. You can relocate the memory to make room for address, in this way the basic input/output system reserves for hardware. Windows Vista cannot access memory which is relocates above the 4GB boundary because of this limitation.

In the available system the reduction is depends on the devices which are installed in the computer. If you want to avid potential driver compatibility issues, the 32 –bit versions of windows vista limit the total available memory to 3.12GB. If you installed may devices in your computer then the available memory reduced to 3 GB or less.

More information about this issue

If the computer is in physical address extension (PAE) mode and has a 4GB of RAM, then a 32-bit operation system can address memory which is relocated above the 4 GB boundary. From the operating system you may know about the correct reports of the installed memory.

If you want to add more memory to the system, then the BIOS might be recognize all the physical RAM even though windows recognize only a part of the RAM. If your computer uses the redundant memory feature or a memory mirroring feature, then the full component of memory may be invisible to windows. If a memory bank fails then redundant memory provides the system with a failover memory bank. If you want to enable or disable these features then use BIOS technique, but you cannot enable or disable these features by using windows. You can modify these features with the computer’s user manual or to the BIOS manufacturer’s website.

If you want to add 4 GB of additional memory and in your computer already has 4 GB of RAM installed, then the Windows recognize only 4 or 6 GB of RAM instead of the full 8 GB.

For this problems of the memory issue (system installed with 4GB of memory), so many companies are shipping their systems configuration with 3GB total in the system

How to Optimize Your System and Get Better Performance on Windows 7

This article gives a list of things that you can do to improve the performance of your computer. First, run the Performance troubleshooter by clicking through “Start > Control Panel”, searching and selecting “Troubleshooting”, and clicking “Check performance issues” under “System and Security”. This will automatically scan your computer and fix any problems that might be affecting your system’s performance. If you still experience problems, use this list to help.

Visual Effects

You can reduce the visual effects on your computer to salvage the speed and reliability of your system. Click though “Start > Control Panel”, search and click on “Performance Information and Tools”, then click “Adjust visual effects” to get to the settings area for this feature.

Check your hardware

Run Windows Experience Index to find out the performance rating of your computer. The program tests your hardware and gives you a rating of 1 up till 7.9. Anything less than 2 or 3 suggests that you may need to upgrade your hardware or change your computer all together.

Random Access Memory (RAM) determines the number of processes and programs a computer can run at any point in time. Increasing your RAM will increase the performance of your system and enable you to multi-task better.

Check your running programs

Your computer will become slower if more tasks that its hardware can handle are running. Changing your computer habits by only keeping programs you need running might help you realize increased performance. Also, check that only one antivirus program is running.

Viruses and spyware are programs that run silently and perform tasks that are unauthorized or undesired by you. A good antivirus/anti-spyware program can protect you from these infection. Programs that run silently use up RAM and reduce the speed of your computer.

Startup programs automatically run when you start your computer. Many of these programs and are designed to do so by default. They often run silently in the background, take up RAM and slowdown the speed of your computer. Stopping some of these programs will also speed up your system start-up. To turn off startup programs by downloading and running this free software from Microsoft.

Clean up and organize your computer

It is good to get in the habit of knowing every program that is installed and running on your computer. Newly bought computers normally have either manufacturer software or third party software already installed. Uninstall any program that you do not use. Some programs run in the background silently and use up your computer resources without your knowledge.

Every time you access it or run a program, your hard disk becomes slightly fragmented. It is similar to slightly displacing objects in your room every time you are in it. Over time, it will become increasingly difficult to find things in your room, or to put new things. The same effect occurs in your hard disk. Defragmenting your disk ’organizes’ the fragments, allowing your system to access your files faster.

Run Disk Cleanup to free up space on your hard disk. This utility will find files on your computer that are no longer necessary. The files normally deleted are the obsolete system files, items in your Recycle Bin, and temporary files no longer needed.

This list covers the main aspects of your computer that affect your systems performance. You can use them to optimize Windows for speed and performance. It is also important to shut down your computer at least once every week if you use your computer extensively. This will clear the memory and stop background processes that have been running which you could not stop.

How to Resolve Memory Gaps

Are you experiencing the following?

  • Poor personal computer performance
  • Frequent slow response on using programs
  • Frequent not responding programs
  • Suddenly freezes
  • Suddenly reboots

Your computer might not have the enough memory it needs to perform programs efficiently. There are two types of memory that a computer utilizes, one is called the virtual memory; this memory is a back up memory used whenever the main memory used by the computer to run the programs are not enough.

Virtual Memory

Virtual memory is a temporary reservoir of files placed into the hard drive as paging file, whenever the main memory is not enough; this is utilized by the computer to provide the needed memory to run the programs. The main memory used by a computer is called the Random Access Memory or referred to as RAM; the RAM is used by all programs installed in your computer for them to run accordingly, this is the memory that defines the speed of your computer.

Low memory problems can be a pain for a computer user; it can limit your capabilities to certain points because your computer is running slow or even hangs up. That is why it is important to keep monitoring your memory and detect if there are any computer memory problems. In times that there are memory problems, Memory Diagnostics Tool will prompt to you.

Memory Diagnostics Tool

Memory Diagnostics Tool is a device built in windows specifically made to address memory problems of the computer. This is composed of many sets of memory tests to diagnose any problems in your computer

Running the Memory Diagnostics Tool

A prompt will come out when there is suspected problem in your memory as shown in the photo below

Upon the pop-up, the diagnostics tool will give you two options to choose from; Restart now and check for problems (recommended), or Check for problems the next time I start my computer. If you choose to restart, make sure that all your works are saved and all the running programs are closed properly, upon restart, the Memory Diagnostics Tool will operate automatically. After finishing all tests, windows will restart. Upon start up, you will be informed of the information gathered after running the memory tests, if problems are found; it is highly recommended that you deal with these problems right away.

More Options for Running the Memory Diagnostic Tools

It is recommended that you let the Memory Diagnostics tool operate manually, but however in circumstances of advanced users who want to adjust the settings, here is how:

  1. On the start of the Memory Diagnostic Tool, press F1
  1. Adjust the settings:
    • Test Mix – you can choose the kind of test you want to run: the Basic, Standard, or Extended.
    • Cache – For each test, you can choose the setting for the cache: Default, On or Off
    • Pass Count – The tests can be repeated by typing the number of times you want it repeated.
  1. Press F10 for the test to start.

In circumstances where Memory Diagnostics Tool is not prompted to you and you suspect a memory problem, you can run the Memory Diagnostics Tool Manually:

  1. Click the Start Button, click on the Control Panel. On the upper right you will find a search box, encode “Memory”, and then click “Diagnose your computer’s memory problems”.
  1. Choose when you want the Memory Diagnostics Tool to run.

How Motherboard Works

Speed and capacity of computers is increasing every day, as a matter of fact better processors are being made each day and there is no limit to the speed of a computer. Ideally, the speed of a computer depends on a number of things including Random Access Memory (RAM), Processor and also on Motherboard.


A motherboard is a very complicated circuit board with a number of components like BIOS already installed on it besides slots for memory, PCI hardware devices, AGP (graphic cards) and a slot for processor. Motherboard connects all the components to the CPU and provides power to them. It contains the bus systems in it which transport the data. A bus system can be of 32 or 64-bit.

How motherboard works

Motherboard provides the only path for components to connect to one another and to the CPU. It works like our nervous system and mainly has to transport data of every type. It connects a number of devices but its basic function is connecting the CPU with other parts of the computer. There are two main bridges on motherboard which connect the various components including the processor.


Area motherboard has two chipsets which connect the various components to the motherboard .They are called bridges and their names are North bridge and South bridge.

North Bridge

North bridge is connected to the memory bus, front side bus (FSB), and AGP bus. Memory bus is further connected to the memory, front side bus is connected to the CPU or processor and AGP bus is further connected to the graphic card.

South bridge

South bridge is connected to the ATA bus and the PCI bus. ATA bus is further connected to the disk drives providing a path between the motherboard and the disk drives including Compact disk drive (CD-drive) and Hard disk drive. PCI bus is connected to the PCI-based hardware devices and thus providing the only path between the PCI devices and the motherboard.

For example, when a person presses a key on keyboard, let’s say key “A”, then this information is sent to the motherboard which sends it to the CPU, which further processes the , information and then sends command to the various components. The graphic card gets the information of displaying it on the computer screen.

The speed of a computer mainly depends on its processor but motherboard also affects it as it contains the bus system and transports the data. If the bus system of motherboard is fast then it would be able to transfer information at a higher speed but if it is slow then the speed of computer would surely be affected irrespective of processor speed. This is because if a processor can work  at a higher speed but the information is not being transferred at the same rate, the computer would work at slow speed.

Earlier, everything except the processor came separately and they need to be connected to the motherboard one by one before using them. But now, a number of accessories like LAN, video and sound supports are preinstalled on the motherboard.

Future of Motherboards

Like other computer components, the size of motherboard is also decreasing, as smaller computer chips are being made. It is expected that in future a motherboard of smaller than  a SIM card would be created and the speed and mobility of computers would be greatly increased.
