HT (Hyper-Threading) is a technology Intel made to enables multi-threaded software applications to execute threads in parallel. In other words, it makes the CPU work about 25% faster for certain applications. You have to buy an Intel CPU that specifically identifies it supports HT.
 If you look at this picture, you will see a small H and T in the upper right of the logo. This specifies it has HT. Here is an article on Hyper-Threading: http://www.intel.com/technology/hyperthread/ I hope this helps.

This specifies it has HT. yeah that's what frustrates me. because my sticker doesn't say HT, but when i run the Tweak-Xp Processor Check, it says it is. could it just be a glitch? |

Sounds like something is not right.

For enabling hyperthreading one goes in the BIOS....but of course your motherboard has to be able to handle HT!!!! (/me kicks shopkeeper of Pc-Clinic... darn non-computer people!). So I got a inferior CPU with HT support....and of course a inferior motherboard of 1994 without HT support...and they told me them both had HT support! (Mind you, I bought it 4 months ago). Info could say you have a HT support processor, but if you can't find where to activate it you might have a non-HT motherboard....good luck!

Hey dude, I don't have and never come across a Hyper-Threading PC... But I think these may help... http://mindfulmusings.net/weblog/2004/10/1...ng-motherboard/ QUOTE 1) Download and install Windows XP Service Pack 2 2) Find the following files (normally in your c:windowsservicepackfiles) - ntkrnlmp.exe - halmacpi.dll and copy them to your c:windowssystem32 folder. (This is considering your new motherboard has ACPI support. I know that these files will support non-ACPI computers as well, but that has not been tested) 3) Open up boot.ini in your text editor and find the following line: multi(0)disk(0)rdisk(0)partition(1)WINDOWS=”Microsoft Windows XP Professional” /fastdetect /NoExecute=OptIn (or something of this sort) and replace that line with: multi(0)disk(0)rdisk(0)partition(1)WINDOWS=”XP Professional MP” /fastdetect /kernel=ntkrnlmp.exe /hal=halmacpi.dll Make sure there are no line breaks in that line. (backup your boot.ini and your hardware profile if you want, that might be a good idea) http://support.gateway.com/s/issues/2-1625912705.shtml http://www.devhardware.com/forums/t31312/s.html http://echeng.com/journal/index.php?p=968 http://ng.csharpfriends.com/top/ng/group~3...-___/index.aspx |

go to www.cpu-z.com and download the CPU-Z program. That program will identify exactly what kind of CPU you are using as well as all the extras that it has enabled like MMX, SSE and hyperthreading.

Right Hyper-Treading not only found in CPU, even if you have CPU with HT supports it still requires a compatibility with mainboard, some board don't support Hyperthreading, there is a mainboard that really designed for HT. In short to enable hyperthreading you must have the two, CPU and the MaindBoard. |

If you fail to enable Hyper Threading, don't cry your eyes out because of it! Take a look at this online article from the PCWorld magazine:
http://www.pcworld.com/news/article/0,aid,107492,00.asp Here is straight-forward comment from them: QUOTE Technology a Bust? Why would a speedier chip that is capable of acting like two processors have so little positive impact on test scores? |
