How can i enable 4 gb of ram in windows xp 32 bit version

You can't. 32-bit, Windows systems can only see/use approx. 3.5 GB.

Even if you upgrade to a 64-bit system, you will still see something less than 4 GB as some may be allotted to mobo devices.

 

Cheers!

I have the same issue. Why exactly do they sell machines with 4GB of RAM when 32 bit OS's are incapable of seeing it?

Because you can normally access almost 4GB. Currently, Dell and others are offering 3GB laptops which retain Dual Channel memory performance.

What model do you have?  Mine is m1530, that came with 3 gb of ram.  I researched the chipset and it's capabilities. 

 

1. Supports up to 8 gb of ram 

    a.  supports memory mapping

    b.  Flex mode(allows symmetrical, Dual Channel mode for unmatched sodimms)

    c.  Dell Bios A09 supports 6 gb of ram (2 gb slot a, 4 gb slot b)

         there are ideas on ideastorm to get Dell to write bios for 8 gb(please promote)

    d.  supports up to 1 gb of Turbo Cache Memory

2.  Windows x32  vista sp1

     a. Reads 4 gb of ram, uses from 3.2 to 3.5 gb.

     b. Supports Turbo Cache Memory (vista only)

3.  Windows x64 vista sp1

     a. Reads total installed minus any motherboard usage

     b  uses all that is read  (my bios shows 6 gb, windows shows 5.5 gb)

     c. Supports Turbo Cache Memory (vista only

     d. Supports 64 gb of ram (IIRC)

According to CPU-Z my unmatched set of 6 gb (2gb x 1, 4gb x 1), is running at Dual Channel, symmetrical mode.  Using Flex mode and memory mapping, Unmatched sets run as symmetrical Dual Channel instead of Asymmetrical mode.

This is using Dells x64 Ultimate disc (dell not supported) All the latest drivers from each manufacturer, all the latest updates from MS. 

You should be happy with the 4 gb, even with only 80-90% being used.  You will be glad when you decide to install x64 in the future, which is where it is going.  Companies are taking notice of the big interest in x64 in the last year.

          

 

 

Hi

 

My model is DELL XPS M 1530 balck 2.4 GHZ 3 mb l2 cache bios version is A08

 

because these model comes with windows vista only i manully installed Windows XP haveing 2 slots 2 * 2gb = 4GB

 

Thank you for sharing your knowledge with us even though we dont get these much knowledge if we call to DELL Customer Care

 

now my system is updated with sp3 with windows xp  Stll Have any Chance to Enable it ?

 

Thank you

Nope. With 32-bit OS, it is not to be had. Very few users will ever be able to take advantage of even 3.5GB in 32-bit Windows as the OS will not use more than 2GB for any one application.

Some peole dont really know that there are such thing as super computers that already use way more Ram than 8BG... But hey never mind. we all have to learn sometimes..

 

 

32 bit OS Like Vista SP1 will report 4GB ram but only use 3.5/3.2 reason is 32 bit only supports max 4GB ram total that includes your video memory 4gb + whatever your gfx has so you should see gfx allocation is slightly larger then the memory it originally supports

 

64 bit OS has a total different approach in fact it can support more than 8GB ram try about 32GB and then some more obviously the hardware technology on consumer computers has not quite reached that potential yet but I have seen server operating with more than what I stated. In fact Their Past Supercomputers.

 

I could baffle you with tech but I get bored easily

would you really need to use 16.8 million terabyte of ram in a 64 bit machine if they let you?
