Normally, I'd guess, it's more annoying if it reports less memory.
The computer has 256 MB installed, but some programs report 768 MB.
Windows XP Control PanelSystem shows 256 MB and so does Task manager (261616 kB). System Information, Total Physical Memory shows 768 MB. The Mainboard module in SiSoftware Sandra shows 256 MB in Bank0/1, Bank2/3 Empty, Bank4/5 512 MB, together 768 MB.
As I understand it, information about installed memory is reported by BIOS. Is there anything in the BIOS or on the mainboard that is not correct configured?
