Tbird Question

[Twinhead]

I have a Tbird 1.2GHz processor, and I am planning to get Abit KT7A motherboard which has 266MHz front side bus feature. How can I know that if this proccessor is suitable for this motherboard? Or every Tbird processor can fit into any 266MHz FSB motherboard? Thanks.

yes Every Tbird fit that mobo

The 1.2GHz will work fine with that board.

You can run it at 100MHz FSB too. (200FSB double pumped)

Some people like to lower the multiplier and run at 133MHz fsb, which is 266 DP'd

In my experience this works fine, as long as you get a good cpu. 🙂

One more question here.
I know that I can set my FSB to either 100MHz or 133MHz, but not 200MHz.
How can I set it to 200MHz?

 

[compuwiz1]

Uh, you missed the point.

100MHz = 200MHz bus internally on the cpu
133MHz = 266MHz " " " " "

You will not find a 266 or 200MHz fsb on any board.

oh...ic

so for my 1.2GHz processor, if I use 133MHz FSB, is the multiplier 9x?
Thanks

You got it! 🙂

I think i also read that you cant use the newer 266 fsb &quot;c&quot; Tbirds in older non A mobo' like the Kt7.
Does anyone know about this.

You're not exactly correct about &quot;100=200 in the cpu&quot; - it is never 200, the clock pulse is 100 everywhere. What happens is that it is &quot;double-pumped&quot; (DDR) so that both the rising and falling edge of the clock pulse are used for data transfer. So, all the clocks are based on 100mhz but data flows as if the clocks were 200mhz.

you need to unlock the cpu before you can change the multiplier. Dont even try 133MHz fsb with that cpu locked at 12x multiplier(12*133=1596)
