Sorry, not entirely true. There seem to be a common misunderstanding about the O/S allocation of RAM.

E.g. WinXP can only allocate 3GB RAM for the O/S, which is often enterpreted as the whole system can only make use of 3GB RAM in total. Actually, XP can only use 3GB RAM for the O/S, any remaining RAM is kindly allocated to applications with a max of 32/64GB for 32/64bit versions of the non-server O/S. The rest

So if I put 4GB in an XP 32 system, XP could potentially access 3GB for itself, but the extra 1GB (generally unreported) will be used by other applications?

The 4GB story is coming from the first release of Vista not reporting the correct amount of installed RAM (e.g. 4GB or 8GB showed up as 3GB), which, quite understandable, lead to a great deal of confusion among guys like us.

I'm pretty sure that Vista still reports 4+GB as 3.25GB or something similar.

Both Vista32 and W732 run smoothly on +8GB RAM, same with XP.

Do you have a link for this, or have some way of testing it, because everything you say here (at least if I'm reading it right) goes against what I've read elsewhere. http://msdn.microsoft.com/en-us/library/aa366778%28VS.85%29.aspx
