Sony SR RAM Question

I know that if you have 4GB of RAM, Vista 32bit can see them but can't use all of them.
How much RAM can your SR use with Vista?
I have one gadget on my SR's sidebar that says about 3100ΜΒ.
My desktop's sidebar says around 3500ΜΒ. That's why I am asking.

Thank you.

 

my system can use about 3111MB of the 4GB

 

Thanks for the reply.

 

i have 3 gb of ram and my system can use about 3410 gb

 

Where you get the info from..?

 

This is not possible.

 

A 32-bit operating system, such as the Windows Vista® or the Windows® XP operating system, can only generate 4GB of memory addresses. Since some of these memory addresses are used by certain hardware components, there are not enough memory addresses left to map 4GB of system memory. This issue can cause the operating system to report the amount of system memory as approximately 3GB.

Some examples of hardware components that use memory addresses are:

Graphics adapter
PCI bus
PCI Express support which may require up to 758MB
BIOS, ACPI and legacy video support

Use the following procedure to view the actual amount of physically installed memory.

1.Click the Start button and then click All Programs .
2.In the All Programs menu, click VAIO Central .
3.In the VAIO Central window, on the Categories tab, click the plus (+) next to System Information to expand the selection.
4.Under System Information , click to select System Information and then click the Open button.
5.In the System Information window, the actual amount of physically installed memory is displayed next to System Memory
