Memory Upgrade on Older PC
originally shipped w/ 128M (ons stick) and Windows ME
upgraded two years ago to Windows XP pro and added 128M to open slot. Last week i purchased two 256M sticks. inserted, boot up fine, Bios recognizes 512M, crucials memory tester recognizes 512, but "system properties" only shows 256 and speed doesn't seem as improved as i would expect. furthermore, when i try to go back to old RAM (128 X 2) - same deal, BIOS sees 256 but system properties only sees 128!??? I have scoured the net for a solution with no luck. can you help!!!????
