i got a weird problem that is, i cannot use 12.5x multiplier with 240fsb to OC to 3.0Ghz.
when i do this, the system juz cannot past the post and reboot then default itself to 200fsb.

but i can boot and running stable with 333Mhz fsb with 9.0x multiplier (3.0Ghz). it's so weird.
then i go testing with 12.5x multiplier and an increment of 10Mhz which gives 210Mhz fsb which result in 2.6Ghz but same thing happen, cannot past the post and reboot itself, then default the fsb to 200.

i didn't touch the voltage setting just letting it to be auto. why would this happen ?

i even tried to download with original 12.5x multiplier with 150Mhz fsb but same thing doesn't past post and reboot itself.

i think i've found the problem that is .... my motherboard can only boot with 200 / 266 / 333 which is (800 / 1066 / 1333 FSB)

dunno why but it is weird, i tried manual set the voltage and even try underclocking at 100fsb (1.25Ghz) and 150fsb (1.5Ghz) but it is still the same.

why am i locked to 200 , 266 and 333 Mhz ?

i tried updated to latest bios, still same. i only have pci-e speed and i locked it at 100mhz, i think this board auto lock pci speed to 33mhz.
