Yes many times regarding Multiple cores.

The other part of your question regarding the ram is simple if the Bios dont recognize more than 3 gigs of ram then nothing else will.

Read the following regarding using 4 gigs under 32bit os ++++ AT YOUR OWN RISK I ACCEPT NO RESPONSIBILITY IF YOU DAMAGE YOUR PC'S++++

When you boot the pc does the bios report 4 gigs of ram.

If it don't see 4 gigs in the bios then XP wont see it either.

If it does see the full 4gigs then follow this:

To enable Physical Address Extension (PAE) X86

1. Open Windows Explorer.
2. On the Tools menu, click Folder Options.
3. On the View tab, click Show hidden files and folders, clear the Hide protected operating system files check box, and then click OK. If you are presented with a warning dialog box, click Yes to continue.
4. In the root folder (for example, C:, locate the Boot.ini file and remove its read-only attribute.
5. Open the Boot.ini file, and then add the /PAE parameter to the ARC path, as shown in the following example for Windows Server 2003, Datacenter Edition:
multi(0)disk(0)rdisk(0)partition(2)\%systemroot%=" Windows Server 2003, Datacenter Edition" /PAE
6. On the File menu, click Save.
7. Restore the read-only attribute to the Boot.ini file.
8. For the change to take effect, restart the computer.

Example:

Original Boot.ini:

[boot loader]
timeout=0
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT=”Micro soft Windows 2000 Advanced Server”
/fastdetect

Change the Boot.ini to become:

[boot loader]
timeout=0
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT=”Micro soft Windows 2000 Advanced Server”
/fastdetect /PAE

Problem: The computer will not start after PAE is enabled.

Cause: Your hardware may not support PAE.

Solution: Start the system and run Safe Mode, which disables PAE. Then remove the /PAE parameter from the Boot.ini file.

To run Safe Mode:

1.


When you see the message "Please select the operating system to start," press F8.

2.


Use the arrow keys to highlight the appropriate Safe Mode option, and then press ENTER.
To use the arrow keys on the numeric keypad to select items, NUMLOCK must be off.

Problem: After PAE is enabled, the computer runs for a time and then displays a Stop error.

Cause: Your hardware may not support PAE.


For Vista 32 bit

Typing "cmd" in the "start" "search" space, and press Ctrl + Shift + Enter. This runs "cmd" in Administrator Mode.

Then type - "run" Type - BCDEdit /set PAE forceenable

This enables PAE but if you have DEP running then its already enabled

Also if you experience any problems if running a Creative Xfi sound card turn off PAE it has been known to cause problems.

Then type - "run" Type - BCDEdit /set PAE forcedisable
