Computer Memory Check

Your computer memory is a set of chips mounted on one or more circuit boards. Each such assembly is called a memory module.

There are different types of memory modules - Single Inline Memory Modules (SIMMS), Dynamic RAM (DRAM), Synchronous Dynamic RAM (SDRAM), Double Data Rate SDRAM (DDR-SDRAM), and so on. See your motherboard documentation to see what type of memory module your computer uses.

The processor of your computer uses the Random Access Memory (RAM) to store data during processing. This type of computer memory is temporary storage - unlike your hard drive which can store permanently.

The more RAM your computer has, the better your processor works since it doesn't have to simulate so much storage on the hard drive.

How to Check the Amount of Memory

In order to check how much computer memory (or RAM) you have, you don't have to physically open your computer. There are several ways you can do this.

Here are two easy ways built right into the Windows operating system:

• Run the System Information program. Start-Programs-Accessories-System Tools-System Information. Click the System Summary branch of the tree in the left pane and look for the value of Total Physical Memory. This might be given in kilobytes. Just divide by 1024 to change to megabytes (MB).

• Run the System Applet in Control Panel. Click Start-Settings-Control Panel. Look for the System Applet icon (near the bottom, if alphabetically listed). Double click (or right click and choose Open). Select the General tab.

In both cases, you will find that the value you see is a little less than commonly expected. For example, 256MB may appear as 244 MB or so. Except for Windows XP which would show you 256 MB.

The System Applet in Control Panel usually gives you extra information too. Look for the speed and type of your processor too.

You can also use the Belarc Advisor utility. It gives you more information than just the amount of memory installed in your computer. Click here to download Belarc Advisor.

If you need more RAM...

And you can never have too much with today's greedy programs and Internet browsing...

I highly recommend you visit one of my very favorite stores. They have great prices on all types of fast computer memory, with superb customer service reputation to back! You will find competitive computer memory prices here.

Non-Volatile RAM?

MRAM stands for Magnetic or Magneto-resistive RAM. Both Motorola and IBM have shown off this non-volatile computer memory.

Non-volatile  means that it does not lose its data when the computer power goes off.

Unlike DRAM,
which is used in computers today, and only retains data when the
computer is on, MRAM mimics a hard disk storage. Is this a good thing or a dangerous thing?

Do you have enough RAM?

Is your computer showing signs of low memory?

What type of memory does your PC use?

Do you have enough Cache Memory?

Do you need a Computer Memory Booster?

NOTE: Most computers now use DDRAM and other high performance modules. If your's happen to use SIMMS, remember that you can't mix different types of SIMMS.
