MAXDOP setting algorithm for SQL Server

When setting up a new SQL Server, I use the following code to determine a good starting point for the MAXDOP setting: /* This will recommend a MAXDOP setting appropriate for your machine's NUMA memory configuration. You will need to evaluate this setting in a non-production environment before moving it to production. MAXDOP can be configured using: EXEC sp_configure 'max degree of parallelism',X; RECONFIGURE If this instance is hosting a Sharepoint database, you MUST specify MAXDOP=1 (URL wrapped for readability) http://blogs.msdn.com/b/rcormier/archive/2012/10/25/ you-shall-configure-your-maxdop-when-using-sharepoint-2013.aspx Biztalk (all versions, including 2010): MAXDOP = 1 is only required on the BizTalk Message Box database server(s), and must not be changed; all other servers hosting other BizTalk Server databases may return this value to 0 if set. http://support.microsoft.com/kb/899000 */ DECLARE @CoreCount int; DECLARE @NumaNodes int; SET @CoreCount = (SELECT i.cpu_count from sys.dm_os_sys_info i); SET @NumaNodes = ( SELECT MAX(c.memory_node_id) + 1 FROM sys.dm_os_memory_clerks c WHERE memory_node_id 4 /* If less than 5 cores, don't bother. */ BEGIN DECLARE @MaxDOP int; /* 3/4 of Total Cores in Machine */ SET @MaxDOP = @CoreCount * 0.75; /* if @MaxDOP is greater than the per NUMA node Core Count, set @MaxDOP = per NUMA node core count */ IF @MaxDOP > (@CoreCount / @NumaNodes) SET @MaxDOP = (@CoreCount / @NumaNodes) * 0.75; /* Reduce @MaxDOP to an even number */ SET @MaxDOP = @MaxDOP - (@MaxDOP % 2); /* Cap MAXDOP at 8, according to Microsoft */ IF @MaxDOP > 8 SET @MaxDOP = 8; PRINT 'Suggested MAXDOP = ' + CAST(@MaxDOP as varchar(max)); END ELSE BEGIN PRINT 'Suggested MAXDOP = 0 since you have less than 4 cores total.'; PRINT 'This is the default setting, you likely do not need to do'; PRINT 'anything.'; END I realize this is a bit subjective, and can vary based on many things; however I'm attempting to create a tight catch-all piece of code to use as a starting point for a new server. Does anyone have any input on this code?
