Your board ran a 3:2 fsb/dram divider since acroding to the ram timings it has no chance to run at 242mhz (effective ddr484) so if you want to keep a 1:1 ratio upgrade the ram or lower the fsb speed and/or loosen the ram timings to 3-4-4-8 to get to a stable 1:1 ratio which is recomended for intel rigs.
