I recently bought a Thunderbird 1.2 GHz chip to upgrade from my Duron 700. I run a Gigabyte GA-7ZX(-1) motherboard. As i understand it the TBird 1.2 came in two flavours: the one with a 9x multiplier and the other with a 12x multiplier. If i run my motherboard at 100 mhz FSB it detects a 900mhz chip. that means to get 1.2 ghz i have to put the FSB on 133 mhz. Right?
My system won't boot up if i switch to 133 FSB. Not even a POST. If I run it at 112 mhz , it boots up normally but at 1008 mhz. i've even flashed my motherboard to the latest bios on Gigabyte's site, nothing helps!

Please! Someone help me!

Hate to be the one to tell you this, but the Gigabyte GA7-ZX-1 motherboard is based on a KT133 chipset, which only supports the 100 MHz (200 Double-pumped) FSB, not the 133 (266) MHz FSB. It will actually do 133 for it's FSB, but that option was only in there for overclocking, so you would be overclocking the AGP and PCI cards way over what they are designed to take, which is why it doesn't POST at 133.

You would be better off getting the 1.2 GHz with the 12x multiplier and 100 MHz FSB, or a newer motherboard based on the KT133A or one of the new DDR chipsets.
