Maximum memory on Windows 2003 Server?
Posted on 2006-11-30
I've been looking at this on and off for the last few months but keep seeing different answers. So can anybody give me some firm answers on this, with references if possible.
If I am building a new server with an Intel based 32bit processor running Windows 2003 R2 Standard Server what is the maximum amount of memory I can put in it that will be used? I have this idea in my head that 4Gb is pretty much the maximum limit. Now I know there are a lot of ifs and buts, so here are the scenarios I have in mind -
1. A server running lots of different applications that in total could use 10Gb RAM. Will 10Gb of physical memory be used if I put it in or is anything over 4gb a waste?
2. Probably the same answer as above; if I havea server to act as a terminal server I want lots of memory for people to use, can I put 10Gb in there and it will be used?
3. A dedicated Exchange server - more then 4Gb is pointless I assume because the maximum that can be used by one process is 2Gb (or 3Gb with the /3gb boot.ini switch)? On the subject of that, is the /3Gb a good or bad idea with SQL or Exchange on 2003 Server Std.?
4. An SBS server doing a bit of everything that coule use 6Gb if it was there?
Is PAE a good or bad idea in the abvoe scenarios? I think I remember reading it can be a bit hit and miss as to which apps it works with?
Thanks very much,
