Well with that said, I noticed a performance increase when I turned hyperthreading off. It looks like im not the only one with this issue I hope dell has some answers for this issue, Its depressing to know that my company spent almost 6K thats incncluding the 20" lcd screen for this pc, and my home pc with a P4 2.

Depending on your operating system, hyper-threading can optimize your systems behavior when running either multi-threaded applications or simply running multiple applications simultaneously.
Windows XP takes full advantage of this by supporting the technology. Windows does not have native support for it but it can be utilized in that environment as well.
However, when utilized under Windows Pro, realize that this operating system only supports a maximum of 2 CPU's. So to enable it with that OS will likely not yield any benefits and may actually have a negative impact depending on the application s. In order to enable this feature in Windows , simply apply the multiprocessor kernel by going into device manager, and under computer, change the processor type from UniProcessor to MultiProcessor and reboot.
Hope this makes sense Cheers Steve. BarbaryLtd 2 Bronze. Yes windows hasn't realy got a way of reporting it correctly. X Donate Contact us. New posts Trending Search forums. What's new.

Archived from groups: microsoft. There are, however, several graphics programs which I use which apparently perform better with HT turned off. Corel Graphics Suite 12 is the most notable fo these. Well not to SP2 yet; waiting to see what happens with that stuff! All software and hardware patches installed and updated; checked monthly.
No problems at all, and I don't see a point in disabling it. What you should do is set the affinity on the application that performs poorly with HT enabled. Force that application to only see the first processor and not the second one.
There was also a neat application I read the other day in here that keeps the affinity settings. Thanks for the reply. I will trouble you with one more question. Asked 16 years ago views.
Systems Deployment OS Provisioning. Posted by: Francoisracine 16 years ago. Why are you saying Sysprep is not a good option? This option is the one use with MS OS deployment? Can we exchange our point of view? Why disabling HT? Are you recovering a uniprocessor image on the HT machine?
Posted by: olivier 16 years ago. No more problem like that with unattended setup. But I don't care. Yes, disabling HT allows me to use uniprocessor image on the pseudo-dual-cpus computers. Personnally, I prefer unattended setup but there is no way to reinstall a big bunch of computers with no need to physically move to those computers RIS F So the HAL would be uniprocessor or multiprocessor?
What is happening when you reenable HT? No issue with uniprocessor computers using a HT image taken with HT disable? After reenabling with the bios, Windows or XP recognise it with no problem. Posted by: auxiliary 16 years ago. Francoisracine, Are you meaning that you like unattended over RIS because you have to push F12 on the machine to boot to network?
If so By default, RIS causes the client computer to display a prompt that tells the user to press F Rename Startrom. We can make unattended by using RIS. If you remove the F12, how will you slect which computer would start a RIS or not? However it is really interesting. What I say is: It is not efficient to have to move to a computer to press F
