We have 2008 R2 server that started consuming 4x the RAM it was using 6 days ago. Went from 1.2GB to using 3.92GB. Issue started on 6.13.2011. Server was rebooted on 6.11.2011. The issue is that this server houses a 3 tiered application that is in development and the devs need assistance finding out what is consuming the extra RAM. But I know that neither Tasks Manager or Process Explorer will show all of the RAM usage. Totaling up Working Set or Private Bytes in Process Explorer never equals anywhere near all the RAM in use. So how do i got about finding where this RAM is being used?Lossless Audio Addict

The rest of the RAM is either FREE or assigned to the File System as Cache. Using Perform check the memory/Free memory. Read these article about file system cache. http://technet.microsoft.com/en-us/library/bb742613.aspx http://blogs.msdn.com/b/ntdebugging/archive/2007/11/27/too-much-cache.aspx

It is explained in the article http://blogs.technet.com/b/askperf/archive/2007/03/29/windows-vista-superfetch-readyboost.aspx. You need not worry about the missing memory, it is freed up as and when required/requested by applications.
