You can use /PAE with Standard Edition (/PAE is required to enable "no execute" functionality, for example - the bit flag used to indicate whether a memory page is not to be executed is stored in the extra 4 bits made available by /PAE).
However Windows Server 2003 x86 has an artificial (inbuilt) limitation that only allows memory addresses up to 0xFFFFFFFFF. If you use Windows Server 2003 x64 Standard, you can avoid this issue. If you need to use x86 edition, you need to install Enterprise Edition (and use /PAE switch) Cheers en From: Ziots, Edward [mailto:[EMAIL PROTECTED] Sent: Wednesday, 9 January 2008 12:20 AM To: NT System Admin Issues Subject: RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS Can we do the /PAE switch in Windows 2003 Standard tho? Usually only put this in on Enterprise Edition.

But there is a good reason to remove it if you have more than 16GB of RAM. Review the Raymond Chen blog posts posted previously... Cheers Ken From: David W.

From 4 - 16 the /PAE works but above that they told me to leave it off. ----- Original Message ----- From: Ken Schaefer<mailto:[EMAIL PROTECTED]> To: NT System Admin Issues<mailto:[email protected]> Sent: Tuesday, January 08, 2008 8:08 AM Subject: RE: HP DL380 G5 and Win2k3 R2 Standard not showing maximum memory in OS If you are running Enterprise edition, then add /PAE switch. /3GB switch is for virtual memory (per user mode process, not physical RAM) Cheers Ken From: David W.

Ran into a strange one this morning. I have a pair of DL380 G5's that I was adding 2 GB of memory to ( Have to add it in Pairs as I found out) and when I got the OS to finally Boot ( DIMM 1A,3A must match with DIMM 5A, 7A for the correct Advanced ECC configuration) the BIOS shows 4096MB of memory on the boot, ( BIOS 4/6/2007), but when I log into Windows I only see about 3.4GB. Checked the boot.ini ( there is no /3GB switch or /Maxmem statements) Any ideas has anyone seen this before?
