I have recently installed a 1Gb memory module. Startup information recognizes it, but Belarc, SiSoft and Crucial read it as 512mb, not 1Gb. Then I get the blue screen!!!! Could I have knocked something?
Ditch999. I have been able to change Memory modules before, without having to touch BIOS. I have 2 modules, and have tried using all modules in my two slots, but still the 1GB plays up. Have gone back to my original layout, 250+700. Suspect 1Gb may be a bummer - it's off E Bay!!
