If a SS database is moved as it is from a 32 bit installation/OS to 64 bit SS/OS under the same load conditions, does it require more RAM memory or the same should suffice for equivalent response/caching?

    Accepted Solution

    It should be same provided both the servers have the same set of applications supported..
    SQL Server should use the same amount of memory..

    You don't need more momory; if your system, applications and sql server were running fine on 32bit edition, you won't need to add more memory when you upgrade to 64bit. I did the same upgrade and everything just work great, and even faster than before ! So keep everything as it is now. Cheers !
