All that has been proven is Windows can't consistently report one piece of information from one location to the other. I indicated earlier that Vista SP1 will show memory installed and not useable memory as well. which will start this conversation all over again then. ;) I wonder what memtest would show? Also, I know we're speaking of Windows mostly here, but this isn't a only limitation so much of Windows or 32bit operating systems, but more a limitation of x86. As a side note, AMD doesn't support /PAE, and I haven't put any time in to finding out what AMD does in these cases.

Importance: High TO all, ( Ken I hate to say it, but I have seen this with me own eyes, and the /PAE switch does enable you to see the 4GB) I have proven that the /PAE switch has worked on a DL 380 G5 system with 4096 MB of RAM at post. Running Windows 2003 R2 SP1. Before putting the /PAE switch in the boot.ini the memory available to Windows ( via MSinfo32.exe and winver was 3.4GB) After putting the /PAE switch in the boot.ini the memory availbile to Windows ( via Msinfo32.exe and Winver was 4GB) The system I tested on was built with 4GB of RAM already in the system, and when it was finished being built showed 3.4GB of RAM available to windows. I don't think this would change if you just added 1-2GB of RAM to a 2GB system to bring it up to 4GB. If someone else with the same architecture can confirm my findings please so we can settle this matter once and for all.
