There is no such limit using a 32bit Windows OS. What you observe is a practical average given modern hardware. But I have a HP ML330 in my house that "loses" about 64MB of memory when using standard Windows Server 2003 x86 edition, not ~600MB.
Read the links and comments from: http://blogs.msdn.com/oldnewthing/archive/2004/08/22/218527.aspx Or buy/read the Windows Internals book by Mark Russinovich/David Solomon Or read the articles on memory management here: http://www.microsoft.com/whdc/system/kernel/wmm.mspx (the memory management whitepaper is well worth reading) This seems to come up every Rnd() months on this list :-) Cheers Ken From: Jeffrey Showen [mailto:[EMAIL PROTECTED] Sent: Wednesday, 9 January 2008 12:14 AM To: NT System Admin Issues Subject: Re: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS I thought a 32-bit OS was limited to 3.4GB of RAM unless you use the Physical Address Extensions in the boot.ini file. The file is a protected file in the root of C:\ (or whatever your boot partition is) so you will need to unhide protected OS files onder folder options. Open boot.ini with notepad and add the /pae switch to the end of the last line (starts with "multi(0) disk(0)rdisk"... etc) and then reboot. You should then be able to see all your memory.
