System Center 2012 Configuration Manager: The original RTM version of Microsoft System Center 2012 Configuration Manager installs Microsoft SQL Server Express 2008 R2 Service Pack 1 (SP1) when you deploy a new secondary site. The minimum supported SQL Server version is Cumulative Update 4 for SQL Server 2008 R2 Service Pack 1 (SP1).
System Center 2012 Configuration Manager Service Pack 1: System Center 2012 Configuration Manager SP1 requires Cumulative Update 6 for SQL Server 2008 R2 Service Pack 1 (or SQL Server 2008 R2 SP2).
You must manually install the Cumulative Update for SQL Server 2008 R2 SP1 on the new secondary site after the site is installed. More information here : http://support.microsoft.com/kb/2688247
Hope it Helps ,
