Technically, i don't know. Bit computer illiterate.
However, if you understand tech-talk from Intel, check this out.
As we have a lot of Intel computers folding in our house, we favoured the ones with HT. With HT enabled (in the bios) we can effectively run 2 wu's independ of each other. A single one with HT disabled will run faster.
First you'll need a HT enabled CPU, any 800mhz FSB Intel CPU and the 3.06GHZ with the 533 FSB will run HT. Second you need Windows 2000 or XP Pro although I've heard SP1 for home adds HT support.
As to what it does it tells the OS that your PC has 2 CPU's and in action divides the work between 2 "logical" processors which I take to be the ALU and FPU parts of the CPU and lets them have the work that they do best on SMP enabled applications although I'm likely wrong about that part and distributes the workload.
On SMP enabled apps you'll see a boost or when you run multiple apps at one time, on non SMP apps you won't see any improvement unless as I say you run several at a time.
It's basically free HP, if your CPU has it and your OS supports it, do it.
NOTE: You don't actually have two CPU's, it does in fact help and overall is faster and better to have HT enabled. You may or may not notice the difference, depends on the application.... like MS Word vs. UT2K4 You may notice UT play better, but if you're just using Word.... yeah, not much help

Get CPUID and post for us what it says, OK??? That Central Processor Unit ID program works well with Intel, from experience.

This is my processor specs. As you can see. I do have hyper threading on my system I dont think its enabled tho.
Technology : No
does not look like the CPU has TH
http://developer.intel.com/design/Pentium4/prodbref/
about 1/3 way down
the 2.66 dose not support HT
the board might, but without the CPU support, it will not work
And yet it says Yes up there in the features.
Oh well guess i dont have hyper threading...
