How much RAM or Memory does my Machine have?

I have a Lenovo T61 laptop.. how do i find out how much RAM i have. Meaning, if it says 2gb does that mean i have two 1gb cards or one 2gb card with an empty slot next too it. Also what is the differernce from Total Physical Memory and Available Memory? It says i have 3072MB of Total Physical Memory and 2.05GB of Available Physical Memory? Well then how big is the card thats in this machine?

Probably the easiest way to determine the answers to your questions is to access the BIOS on the laptop.

To do this on your laptop Press the blue ThinkVantage button when the message "To interrupt normal startup, press the blue ThinkVantage button " is displayed to enter the ThinkVantage Productivity Center, then select Start setup utility to open the BIOS Setup Utility.
Use the below VB Script to show what memory is installed and in what slots (copy to a text file and save with the VBS extension)

see here for a description on Physical and available memory


strComputer = "." ' Local computer
strMemory = ""
i = 1
set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
set colItems = objWMIService.ExecQuery("Select * from Win32_PhysicalMemory")
For Each objItem In colItems
	if strMemory <> "" then strMemory = strMemory & vbcrlf
	strMemory = strMemory &  "Bank" & i & " : " & (objItem.Capacity / 1048576) & " Mb"
	i = i + 1
installedModules = i - 1
Set colItems = objWMIService.ExecQuery("Select * from Win32_PhysicalMemoryArray")
For Each objItem in colItems
	totalSlots = objItem.MemoryDevices
wscript.echo "Total Slots: " & totalSlots & vbcrlf & _
	     "Free Slots: " & (totalSlots - installedModules) & vbcrlf & _
	     vbcrlf & "Installed Modules:" & vbcrlf & strMemory

You have 3GB of physical memory.  You have 2GB of Available memory because 1GB is being used by applications and the operating system.  Available = total - used.

You may also see that you have virtual memory available.  Windows (and many other operating systems) use virtual memory or page files.   This helps, but it is much slower than physical memory.
The best IMHO is to use CPUZ from It will show you how many slots are filled, what you have available, at what speeds, how many memory modules installed, etc.
You can use SIW to show you all information on your PC.

Many PC's share their RAM with the Graphics card, so of your total 3GB 1GB is probably used for the Graphics card.
Either one of those ways will work but I also often use a little program called CPU-Z that displays in depth specs of main system components.  It will tell you how many modules and details about each one among other things.

You can download it there and it's a quick install.
oops.  Seems someone posted the same thing while I was typing.  Didn't mean to double post =/

Im using this and dont know what i am looking at...Type DDR2 Channles Dual Size 3056 MB DC Mode Symmetric
When using CPUZ on the Memory tab under General it will display they type, size, and performance mode (Dual Channel, Single Channel). Under the Timing it tells you the frequency of your memory timing. The SPD tab will show you how many slots you have. Using the drop down if you have memory installed in Slot 1 with module size 1024 MBytes, that means you have a 1GB memory module installed in slot 1.
