i found this about the emt64
The EMT64 chips are still 32 bit
chips. Intel will not have any 64 bit consumer chips until next year.
EMT64 (Extended Memory Technology 64) chips allow a P4 chip to
use the same registers that a 64 bit chip accesses, so that they can use
more than the 4GB that a non-EMT64 P4 can access. As a side advantage of
this, the chip can "execute" the x86 code, but it does so through emulation
using a 32 bit thunking layer. It does not run the 64 bit OS as a 64 bit
OS, but as a thunked OS. This is slow and clumsy at best. The point I am
trying to make is that the EMT64 bit chips *ARE NOT* 64 bit chips. They are
able to use certain functions of the x86 extensions that allow it to access
the same registers, but that is all. It is *NOT* a 64 bit chip, not will it
ever be. Intel has announced that it *WILL* produce 64 bit chips next year.
I want those who are considering buying a 64 bit computer to understand that
while the EMT64 can emulate execution of the code, it is *NOT* a 64 bit
chip. Never was, never will be.
Intel produces no consumer 64 bit chips.
The Prescott "J" model with the EMT64 designator is a Pentium 4 chip. Like
all other P4 chips, it is 32 bit. The EMT64 stands for Extended Memory
Technology, and allows the processor to use the x64 core coding to address
more than 4GB of RAM. It will emulate running the 64 bit code in Windows Xp
x64, but will run it in 32 bit mode only.
anyhow,.. you cant disable HT as far as i know, and i think your processor has it for sure.

Hyper Threading just makes your operating system think there's two cores while there's actually one and is used by INTEL. Hyper Transport is used by AMD is it is similar to the front side bus like pc eye said.
Since hes talking about a Intel, Hyper Transport is sort of a mute point!
You will find here that he was trying to understand how to "ENABLE Hyper Threading" on the Intel model cpu there. But you couldn't be expected to understand that.
!The actual method for enabling this is described as,
Hyper-Threading Technology1
Hyper-Threading Technology enables a single processor to execute two separate code streams (called threads) concurrently allowing a single processor to function as two “virtual” processors which significantly boosts computing performance to keep pace with today’s applications and operating systems. This increase in efficiency of the processor translates to greater productivity for the business owner and a richer digital media experience for the average consumer.
Enabling Hyper-Threading Technology requires a computer system with an Intel® Pentium® 4 processor with HT Technology, a chipset and BIOS that utilize this technology and an operating system that includes optimizations for this technology. Performance will vary depending on the specific hardware and software you use. http://www3.intel.com/cd/channel/re...1hg2/sales_tools/prod_photo_ad_copy/36124.htm
