In XP, Total Physical Memory shows incorrectly in System Information. However, the amount shown in "System" from Control Panel does show correctly @256MB, but the amount from Sys Info from Accessories/System Tools/System Information does not, and shows 192MB, i.e. at exactly 75% of actual total memory on board. I have 2x128MB with a 3rd slot empty. The modules have been removed and reseated, just to check that, but nothing changed. General info: I'm running an Athlon 750 on an Asus motherboard. I just changed the HDD and went from 98SE to XP on it. The HDD is from another computer which ran on P4 system. It is partitioned x3. I reformatted only "C" where XP was installed clean. I actually do not know if this Total Phys Memory problem existed on the computer before I upgraded, as I hadn't checked it for a long time. Is this familiar territory? I'm lost here and don't know why this would show up in this way.
