getting hyperthreading to work
This is a discussion about getting hyperthreading to work in the Slack Space category; I was wondering I am upgrading from a P4 2. 4 533mhz to a 3. 06ghz with hyperthreading,I have been told that I must re-install my entire OS from scratch to get hypthreading working properly in Windows XP.

From what I understand you will need to reinstall the OS.
Easy peezy that is. here how to do it.
1) make sure HT is enabled in bios. Dont worry, windows will still boot, but only see 1 cpu.
Goto device manager>computer. Uograde the driver for "ACPI uniprocessor pc" force the driver for "ACPI multiprocessor PC"
Note that this may cause issues, but on my motherboard it worked fine, so give it a shot, nothing to lose in trying. After you reboot windows will freak out and find all your hardware again, so have your drivers handy just in case.
Most of the time this works just fine.

If you run into problems doing it that way though, do a reinstall of the OS and remember to enable Hyperthreading in your PC BIOS.
If I may just tell you of the method I used when I upgraded from a 2.53Ghz P4 to a 3.06Ghz one a few months ago:
1. Install new CPU
2. Go into BIOS and make sure HT is enabled. It should be by default but it is worth checking.
3. Boot into Windows XP.
4. Wait approx. 10-15 seconds
5. When the "Your new hardware is installed, please reboot" message appears do as you are told
6. After reboot your new CPU will be recognised as 2 - HT is now working.
No reinstallation of OS required, no user intervention required at all.
Let WinXP do the job for you!
