Well I've build already 4 of the E's and dozens of the DLx and none had let me down and all are used being OC'ed (400-500FSB range depending on CPU and cooling)... you just got some bad luck there mate... maybe you got ya bad board back as RMA (I had a shop owner who did a sort of trade behind the scenes, he just gave back my damaged board. But I nailed him as I put a small marking on the sticker and immediately recognised my own board...)
