Can you set a pagefile more than 4GB?

Memory dump of the entire system:

1. Create or set the following registry value:
Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters
Value: CrashOnCtrlScroll
Data: 1

Note You must restart the computer for the changes that you made in the register settings to take effect.

2. Right-Click on the "My Computer" icon on the desktop and select "Properties", then click the "Advanced tab. On the "Advanced" tab, click "Settings" under the "Performance" header. Click the "Advanced" tab, then click "Change" under "Virtual Memory". Set the pagefile to be located on the partition where the OS is installed, and set it to be equal to Physical RAM + 50 MB.

3. Also in the "System Properties" window on the "Advanced" tab, click the "Settings" buttun under the "Startup and Recovery" header. Make sure "Complete Memory Dump" is selected (see 3a if this is not in the list). You can change the location of the memory dump file to a different local partition if you do not have enough room on the partition where the OS is installed.

3a. If the "Complete Memory Dump" option in step 3 is not available, you will need to manually set this registry value:

Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl
Value: CrashDumpEnabled
Value: 1

4. You will need to reboot for these changes to take effect.

5. The next time that the system is exhibiting the problem you were asked to dump the machine for, hold down the RIGHT CTRL key and press the SCROLL LOCK key twice to cause the machine to bugcheck and create a memory dump. After the box comes back up, you'll find the resulting memory dump file in %systemroot%\memory.dmp that can be analyzed
