No offense, but he said in his second post that he is running it @ 10X133 now for 1333mhz. So he is already running @ 133 FSB. He is not running @ 13 x 100 and trying to set to 133mhz. I understand what you are trying to say, but I think by reading his posts, that is not what his problem is. Plus he says it post and gets into Windows before it crashes, he wouldn't get that far @ 13 x 133...🙂
