CPU's FSB match Motherboard's?????????

[sam1]

Hi. Amd Athlon 64 socket 939 CPUs have 2000 MHz FSB right? Do I need a motherboard that supports 2000MHz FSB too, to use all of the CPU's FSB?

If a motherboard only supports 1000MHz FSB, is it gonna only use half of the CPU's FSB?

2000Mhz is not really the actual bus speed... that bus rate is split into 4 parts using quad-data rate so the FSB is only 250Mhz or 200Mhz. what matters is you should match the kind of core that the mobo can support w/ your CPU's core.

So a motherboard like A8N-Sli or A8N-E supports venice core right? I think they support any core of Athlon 64s.

For example some websites say that A8N-E supports 1000MHz bus speed, but Athlon 64 socket 939s all have 2000MHz of bus speed, I was afraid of that 1000MHz would be unused. After reading at a random forum, a guy says that with Hyper Transport, Amd's CPUs run at double speed. So a motherboard with description of 1000MHz bus speed and supports Hyper Transport Technology, it is the same as saying this motherboard supports 2000MHz bus speed. Is this correct?

yes, that mobo can support all kinds of A64s. I think the 2000Mhz pertains to the FSB of the CPU & the 1000 Mhz pertains to the FSB of Hyper-transport
