I have CPU Pentium 4 506 2660 on the motherboard GA-8I945GMF and 4Gb RAM. In
specification of this motherboard is text:
"4 DDRII DIMM memory slots (supports up to 4GB memory) *
* Due to standard PC architecture, a certain amount of memory is reserved
for system usage. For example, 4GB of memory size will instead be shown as
3.xxGB memory during system startup."

When computer is starting I see only 3.24GB in BIOS.
Windows Server 2003 R2 Ent x86 see only 3.24GB.
Windows Server 2003 R2 Ent x86 with /PAE key dont start quite.
Windows Server 2003 R2 Ent x64 see only 3.24GB.

Please help me! I want to use all of 4Gb.

You may have a bad chip on one of your ram sticks.
To test this:

(1) Install only two sticks (because of dual channel)

(2) Boot your system and see how much RAM is listed.

(3) Install the *other* two sticks

(4) Boot your system and see how much RAM is listed.

(*) One the of two configs will have a different amount of RAM
listed             than the other if you have a bad chip.
(5) If so, take a stick from the known good pair and install it with
one     of the sticks from the known bad pair.
(6)If the one you installed first comes up good, then try the other        
stick from the "bad" pair just to be sure, but it is probably             bad.

I know my wording is about as clear as mud, but you should get the idea.
If you need further clarification, do not hesitate to ask.

On 32-bit systems, the PCI bus consumes from half a GB to three quarters of
a GB of address space.  So 4GB of ram will almost always report  as less
memory.  Your motherboard specification is telling you that you simply won't
wee 4GB of memory, so testing your memory is a waste of time.

There isn't much to say if you can't see the full memory from x64. This
is a limitation of the hardware you're running.
