i don't get it mine is lasting well and i hammer mine on the net and gaming. i'm going to see when i have to plug it in to mains cos it's usually around 2-3pm. i'm on default with the values changed and it's stable. i can't go up to 805 with SR because it keeps rebooting so have to keep it at 750. at present it's looking pretty good. going to look into what vi_ posted though
