I have X5DAE board and using 6pcs 1GB Samsung modules is one of your recommended memory, but it only reported 2.8GB in Windows 2000, why?
Please make sure you have newer BIOS(later Rev. 1.0c) from our web site and using Windows 2000 Advanced Server (For up to 8GB physical memory support) then add /PAE in the end of last line of your C:\boot.ini).
