4 Gb RAM?

If it is one of the 64 Bit versions of Vista not a problem you can use more than 4 GIGS of RAM.

If it is a 32 Bit Version of Vista it will say that it accepts 4 GIG but will be a bit less. Of course if you have On Board Video there will be even less available to Vista to use.

Windows 32 bit systems (XP AND VISTA) only recognise up to 3gb of ram. In 64 bit operating systems then you can add on more memory (depending on your motherboard).

Please post back if you have any more problems or questions.

While turning off services can help sped up your system, it won't allow your system to access more of the installed memory.

I believe there is a TR download that lists services that can be disabled.

In order to be able to access more of your installed RAM, you need to reduce the amount of resources that the system needs to access.

In BIOS setup, start by disabling every port and resource that you don't use.

If you have a PCI Express video card, the more RAM on the video card, the more system RAM address space you loose.

What goes on, is that with a 32 BIT OS, the upper 500 MB to 1.5 GB of RAM address space is used for temporary storage registers.

The motherboard manufactures have started reporting all installed and ignore the reserved address space. Prior to this, users used to complain about why the BIOS did not report all of their installed RAM.
Any way you look at it, you need to switch to a 64 bit OS if you want to use RAM sapce above 3 GB.

I have a brand new Dell Inspiron 1525 duo Core 2 2.0 mhz with vista home basic (32 bits)
I would like to know how I can use the 4gb of RAM for maximum performance?

Thx 4 ur time

What basis do you have for your (may I say it BOLD) statement that you "[i]use all 4gb with 32bit[/i]"?

The system will use all 4GB but YOU won't have access to it.

Of the Case as well but there is no 32 Bit Version of Windows that can use it.

Just because you fit the RAM to the M'Board doesn't mean that Windows can address it or Map it as a 32 Bit Version of the Production Versions of Windows can not use 4 GIG of RAM. It just shows that you have more money than sense.

Yes, your system should REPORT all of your installed RAM.

However, NO 32 bit version of Windows can USE all of the installed RAM.

Check out this Microsoft article:

Then run Msinfo32.exe to see how much of the installed RAM is available for use.

My guess is that you will have between 2.5 and 3.1 GB of RAM available.

This is how Microsoft and the motherboard manufactures are responding to customers who get upset about all of the RAM they installed not showing up. Rather than let you know how much RAM is available, they are telling you how much is installed. Even if you cannot make any use of 25% of your installed RAM.
