But Windows XP SP2 and Windows Server 2003 Standard x86 have an inbuilt limitation that restricts addressing to 0xFFFFFFFF and below.

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?
