2 GB RAM - Detected Only 510 MB Tags: Memory RAM Last response: January 9, 2013 12:14 PM in Memory Share hybridbhau December 31, 2012 9:37:24 AM Hi My system has 2 GB (DDR2) RAM installed but the system only detects 510 MB and even uses 510 MB which leads to performance bottleneck . The worst part is that my BIOS says 0 MB Physical Memory but it displays the its FSB . I have tried re-inserting the RAM and clearing CMOS by the jumper but it didnt had any effect . Please help .
