T-birds and buses

[Guest]

Im a little confused, With the 1gig T-birds, are these prossesors running at 100MHZ bus with a 10x nultiplier, or are they running 133MHZ bus at 7.5x miltiplier. I was told to get 133MHZ ram for my new T-bird, but if Im not over clocking the chip, and its a 10x running at at 100mhz how will it effect me?

Any help will be appricated.

Somebody please correct me very quickly here if I'm wrong, but I think both options are in play.
The Tbirds of today and yesterday, run at 100Mhz FSB double-pumped to 200 effectively. I think the RAM is still (somewhat independently) clocked at 133Mhz though...

the completely new boards and the -C versions of Athlon Tbird available today have the FSB run at 133 pumped to 266, and DDR RAM running at that 266Mhz...

I think...

If you have a motherboard with the VIA KT133 chipset (Asus A7V, Abit KT7, etc...) then you have the option of running your memory asynchronously. The CPU will transfer data at 100Mhz DDR and the memory will transfer data at 133Mhz. PC-133 RAM is usually no more expensive than PC-100, so you should probably get it no matter what.

Yup as far as I know this is correct you will have a mem controller to disconnect your CPU external bus and you mem bus speeds...
