Activate Hyper Threading Technology




Hyper Threading Technology is an innovation that enhances the performance of processors
significantly improved.
A hyperthreading processor reveals itself to the system as having two processors
but no additional arithmetic units. A 2 CPU is practically emulated, so it should
Performance increases of up to 40% are possible.
The second thread is only there to monitor the utilization of the processing units of the Pentium 4
to improve what at least some applications designed for multiprocessing
sped up a few percent. In addition, the parallel operation of several applications improves
the response behavior.
Intel itself speaks of a perceived increase in performance here.
The speed advantage of hyperthreading can only be used if you have an HT-capable
Operating system and software with threads or hyperthreading-capable software is used.

This technology was initially developed for Xeon server processors.
In the meantime, the Intel Pentium 4 processor has also made it suitable for desktop PCs, notebooks, etc.

While the correct settings should be in the factory when buying a new PC,
it behaves differently in the case of an upgrade. Some changes probably need to be made here
carried out so that the operating system recognizes the new HT processor.


The following are required for the successful use of HT technology:

  • A processor suitable for HT technology
  • A motherboard suitable for HT technology
  • The ACPI power management (APM does not offer any support).
  • An operating system that contains optimizations for this technology.


In particular Windows XP Pro and Home, Microsoft NET Server and Linux 2.4.x>. Windows 2000
also offer support, but benchmark tests show for various applications
only a small increase in performance.



After the processor has been replaced, Hyper Threading Technology and ACPI
activated. Most boards automatically recognize the new processor and take the first settings
automatically before - please check.
After the OS has booted, it initially does not recognize the new technology.
Now the Device Manager is called up via Start> Settings> Control Panel> System> Hardware.
After clicking on the entry Computer, the entry ACPI Uniprozessor should appear.
Right-click to update this driver.
(Do not search, but choose the new driver to be installed yourself).
Please use the ACPI multiprocessor PC in the list that appears.
After a restart, the processor should also have been recognized by the operating system.
(Please check whether 2 processors are listed in the device and task manager.


It is a little more difficult if after clicking on the device manager entry Computer
Standard PC appears.
This entry means that APM is installed on the system.
In this case, the above instructions will not work.
Here the OS can only be set up from scratch or the repair option can be used.

Using Registry Editor or its tips incorrectly can cause serious problems:
which affect the entire system and require a new installation of the operating system.
