Hi all,

It seems whenever I see any reference to the 3400, it is stated to have a 400 FSB.

But the bios is set at 200 FSB. So which is it, 200 or 400 FSB?

What should the bios setting be for FSB?

Isn't it 2 X 200?

An FSB in the 'classical' sense doesn't really exist anymore on the K8-platform(i.e. Athlon 64/Athlon 64 FX/Opteron)...
Read this' ">http://forums.amd.com/index.php?showtopic=11141 for more info, especially part III.

Anyways, if you define the FSB as the connection between the CPU and the rest of the system(regardless of whether a memory-controller is involved or not), you could say the CPUs' Hypertransport-link replaces the FSB(or it IS the FSB if you like).
On the current Athlon 64 and Athlon 64 FX models, this Hypertransport I/O-link runs at 800MHz using a DDR-technology which results in an effective clockspeed of 1.6GHz.

Btw, the '200MHz'-setting refers to your processors base-clock. It's 200MHz for ALL current K8-class processors, so leave it at that value unless your planning to overclock.

Thanks very much Greyhound.

I figured that I just did not understand the ratings....which you so graciously provided.
