Talk:Athlon 64 Overclocking Guide

From Extreme Overclocking

Some corrections.

"The AGP and PCI Bus' are tied together on all motherboards that I know of. They are also derived from the FSB (Or HTT in the case of AMD) frequency by a divider."

It is not the HTT it derived from, but the main/base clock that is fed to the CPU by the motherboard. This main clock is the basis for most clock-generation: so the HTT clock, using the (adjustable) HTT-clock multiplier; the core clock, using the core-clock multiplier. And also the AGP/PCI clock, in case no lock on it.

"NVidia NForce chipsets have whats called a PCI/AGP Lock. This keeps your PCI and AGP Bus at a constant speed no matter what your HTT bus is."

Yes it has, but sometimes it's switched off by default, and somehow (depends on bios) you have to activate it. (And again, it depends on the main/base clock, not HTT clock [which is a multiple of the main/base clock].)

There is also a few instances in the text where there is HTT written instead of main/base clock.
