Checked KB and this forum, nothing useful. 4gb in 4 sticks working on startup
and memory check. All sticks checked ok and all swap configurations done.
Only 3gb showing in XP pro system and task manager performance. 3gb switch
set in boot and working for applications at 2.701mb. SP2. Latest bios level,
server MB supports 6gb.

That's normal. XP has a 4GB address space but programs can only access
3 GB if the /3GB switch is set.

Sorry, did not answer the question. XP sees only 3gb with 4 gb installed.

It did answer the question Windows XP can see 4 GB of memory space.
Unfortunately it cannot use 4 GB of RAM. Some of the address space is
reserved for other purposes. If you hunt around you can find tweaks to get
around 3.25 GB. Any more you'll have to get the 64 bit version.

This is not exactly the case. The remaining 1 or 2 GB are used to map the
OS into the user space. So, in fact the extra space is far from unused.

That sure sounds like "reserved for other purposes" to me!

Thank you, the article was helpful although it pushed my expertise. I seems
like SP2 is causing the low reading. It was not clear if the memory is being
used and not reported by sys properties or just ignored. The condition of
4gb or more was met but /pae was not. We have SP2 but not /pae in boot.ini.
We do not understand why with 2gb, 2gb is reported. With 4gb, 3gb is
reported, although it may be that some drivers act differently with 4gb and
SP2 changes the reporting to avoid a compatibility issue. Since we are not
running PAE, I am not sure why we have the problem.
