Thanks, Jeff. Excellent article!

I'm pretty sure only motherboards with the Intel 875 chip set will have
hyper-threading capabilities.

A few motherboard companies figured out how to "un-officially" do it with
the Intel 865 chip set.

There's more information about this at the usual places:

Both counts being hyperthreading's access through bios and the cpu it was
introduced on. Actually, the P4 3.06 gHz chip is the P4 that it was
introduced on, but it was also introduced on the Xeon 2.2 gHz AND became
part of the chip on some slower P4s, so I assume it was already built into
the production process, so I was kinda right and kinda wrong. As far as the
statements about hyperthreading, I feel ok about them. And while I know
that hyperthreading was a bios selection in the early Xeons, I'm not so sure
about the P4s, but I will bow to greater knowledge.

I pretty much gave up on constantly keeping up with CPUs when I got a system
together that would do most anything I asked of it. I somewhat got tired of
having arrows in my back all the time by being a first adopter and beta
tester. Now I get to work on music, not on computers! <g>
