I tested my chip on another board and the FSB is still no more than 470 to post (reboots in BIOS) and also ~ 455 - 460 FSB max for 24/7, all I can say its good chip, but bad scaling with fsb, 450 fsb with 1.3v FSB voltage and 1.5v PLL, perfectly for 450 x 8.5 with 1.225v in BIOS for 150 loops of Intel burn test, but no more, and not the chip for me Wthis is with L845B.
