@Dashrender said in SQL Server Express Edition Ram upgrade - suggestion.:
Where does the above mentioned caching come in?
The two biggest places are disk caches and application caches. For example, does all of SQL Server get moved into memory or only part of it? Does all of the database get moved into memory, or only part of it? (That last part is the part that gets capped at 1GB.) Do all of the OS components get loaded into memory, or loaded from disk as needed? Do the log files stay in memory?
