Q & A: the maximum RAM supported by SBS 2003 R2

Postby chicagotech » Sat Dec 16, 2006 10:34 am

Q: What will be the maximum amount of memory supported by SBS 2003 R2?
A: For SBS R2, the same maximum amount of RAM as SBS 2003 SP1, which is also the same as Windows Server. You can use the /PAE switch in the boot.ini to get 4GB RAM to recognize.

Note: you may be benefit from the /PAE switch in combination with AWE
configured on a SBS 2003 running SQL in AWE mode. Please refer to the following links

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.
