[Swap] kb274598: A full memory dump cannot be performed on a computer with 2 GB or greater Ram

From: http://bbs.winos.cn/thread-25733-1-1.html

Symptom
If the ram of the following computers is 2 GB or larger, you cannot perform a full memory dump on these computers:
• Computers Based on Microsoft Windows Server 2003
• Microsoft Windows XP-based computers
• Microsoft Windows 2000-based computers
In the "Write debugging information" in the "Start and fault recovery" dialog box in "System Properties", only the Options "Small memory dump (64 KB)" and "core memory dump" are available, the "full memory dump" option is unavailable.

If you set the crashdumpenabled DWORD Value in the Registry to "1" to perform a full memory dump on a computer running Windows XP or Windows 2000, in this case, memory dumping is interrupted when the computer is shut down unexpectedly.

Solution
Important: We recommend that you consider the following before performing a full memory dump on a computer with more than 2 gb ram:
• On a computer with more than 2 gb ram, it takes quite a long time to create a full memory dump. This will shorten the overall normal running time of the system.
• Due to page file size requirements, it takes a very large system partition to perform a full memory dump on a computer with more than 2 gb ram. If this option is selected, the boot volume must have a page file that is large enough to accommodate all physical Ram plus 1 MB capacity. A full memory dump file requires additional space, because windows also writes a header in addition to the memory content. The header contains a Failover signature and specifies the value of some core variables. The header does not need the whole MB space, but Windows uses MB as the increment to determine the page file size.
• A full memory dump file is rarely required. In most cases, the core memory dump is sufficient for analysis. Consult your upgrade channel before performing a full memory dump in the production environment.
• If your computer's Ram exceeds 4 GB, you must configure the boot. ini file to start the computer that uses the physical address extension (/PAE) switch. For more information, clickArticleTo view the articles in the Microsoft Knowledge Base:

Windows Server 2003, Windows XP 64-bit Edition Version 2003, and Windows XP Professional x64 Edition
To modify the Registry to specify that you want to use a full memory dump file, set the crashdumpenabled DWORD Value to 1. For example, type the following information at the command prompt and press Enter:
WMIC recoveros set debuginfotype = 1
To modify the Registry to specify that you want to use the D: \ dump \ mem. dmp file as the memory dump file, set the dumpfile extensible string value to D: \ dump \ mem. dmp. For example, type the following information at the command prompt and press Enter:
WMIC recoveros set debugfilepath = D: \ dump \ mem. dmp
To modify the Registry to specify that you do not want to overwrite any previous core or full memory dump files, set the overwrite DWORD value to 0. For example, type the following information at the command prompt and press Enter:
WMIC recoveros set overwriteexistingdebugfile = 0
Note: After using these methods to enable full memory dump, the "Write debugging information" section in the "Start and fault recovery" dialog box in "System Properties" still lists "Small memory dump (64 KB)" and "core memory dump ". The full memory dump option is still unavailable. You must use the Windows registry to configure the full memory dump option.

All other versions of Windows XP (including Windows XP 64-bit Edition Version 2002)
You can solve this problem using any of the following methods:
• Place the maxmem = 2000 parameter in the boot. ini file to limit the amount of memory that Windows 2000 can access.

-Or-
• Use a Windows XP-based computer to create the "small memory dump" option or "core memory dump" option.

Windows 2000
For more information about how to solve this problem on a Windows 2000-based computer, click the following article number to view the article in the Microsoft Knowledge Base:
820361 (http://support.microsoft.com/kb/820361/) cannot perform full memory dump on a computer with 2 GB or greater Ram and based on Windows 2000

Alternative Method
You can solve this problem using any of the following methods:
• Place the maxmem = 2000 parameter in the boot. ini file to limit the amount of memory that Windows 2000 can access.

-Or-
• Use a Windows XP-based computer or Windows Server 2003-based computer to create the "small memory dump" option or "core memory dump" option.

Status
Microsoft has confirmed that this is a problem with Microsoft products listed in the apply for section.

More Information
in the Windows 2000 datacenter server help file, the following error indicates that a 4 GB memory dump can be created:
full memory dump: it cannot be performed on a system with 4 gb ram or with a physical address extension (PAE. This dump records all the content in the system memory when the system goes down unexpectedly. If this option is selected, the boot volume must have a page file that is large enough to accommodate all physical Ram plus 1 MB capacity.
