Hey
I just got a new Intel CPU that supports hyperthreading but while
benckmarking I noticed that it isn't enable. Does anyone know how to enable
it. I am running XP Pro if it helps.

You are aware that Hyperthreading will actually slow your system down in
most cases, are you not?

It is great for multitasking but its true what Boby said

Depends on the OS and program design. In Windows, Hyperthreading probably
isn't the best idea. In Linux or other modern operating systems,
hyperthreading works as advertised.

Granted, but the OP is obviously using Windows. The OEM shipped his machine
with HT disabled for a reason.

I understand that. I was just giving the OP some options if they want to
fully utilize their hardware. Not everything can be solved with Windows.

I take it you never tried to import 750,000 lines of text into an Excel
spreadsheet and use the computer for some other task? The above task
basically locked up my computer for about 2 hours. Upgrading to a HT
CPU did not improve the import time but did make the computer usable
while it was doing the import.

I have no problem doing that on my computer. I frequently deal with
datasets that have twice that many lines.

I will admit that when I used to have an Intel processor, it was
problematic.

With my AMD Athlon 64 X2 dual core with hyptertransport and direct connect
architecture, I have no issues.

With Intel, the (lack of) FSB is what hobbles it and brings the system to
it's knees.

Exactly why hyperthreading is so good.

It's not about speed--but other than for gaming we don't really need
speed most of the time. It's about not bogging things down when we do
something compute-intensive.

It also makes it much safer to actually use your computer while
burning. In the days before hyperthreading it was much easier to
starve the burner.

Not true, in fact, it only slows your system down in a few cases that
most users might run into.

Many machines ship with it disabled for support reason and not for
performance reasons.

Of course a dual core is preferable to a single core, but so is HT.
When I built the computer dual cores were not available from Intel and I
needed to be able to do more than one thing at a time with the computer.

What was bringing my computer to its knees was the MickeySoft OS and
Excel. I can do similar projects with AIX with no problems but
unfortunately the project was to create an Excel spreadsheet so I had to
use Windows XP and Excel.
