i have a Compaq Presario 2568CL, and my info says HT supported, not enabled. how do i enable it, and are there any possible pitfalls in doing so?

[LeAnn Rimes My Angel]

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...gy/hyperthread/

I hope this helps.

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...

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)

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:

Here is straight-forward comment from them:

Technology a Bust?
Why would a speedier chip that is capable of acting like two processors have so little positive impact on test scores?

yeah well after all this i wasn't able to enable it. Guess the motherboard doesn't support it. i wanted to speed up my work in premiere, but i'm thinking now of just buying a good desktop and forking over the extra cash rather than tinkering around with the laptop.

I think I may have found a answer for you guys I am testing it, though I can't take the credit.. here is where I found it....
http://mindfulmusings.net/weblog/2004/10/1...ng-motherboard/
going to try it..
ttyl

ciao
I can email you the files you need it wouldn't let me attach them to the bottom of my post
by the way those files are for windows xp pro 2 not tested with any other oss may or may not work with other oss if un compat just revert the boot.ini to fix.

How do you find out if you have hyperthreading enabled or not? I have no idea, thanks

You Three finger salute, (press control alt delete) then select the performance tab...
then hold alt and press v then c then p if you don't see two graphs for your cpu usage, and you have a pentium 4 Hyper Threading processor you need to contact me or follow the advice on that page.. have a good day ..

[iGuest]

Replying to grnjdIt is easier then it sounds just check the device manager and see if it has two proccesors listed. If it does you have hyperthreading enabled.

[iGuest]

Compress something using 7z. If all processors goes up to 100% (or close to 100) then you are Hypertheading. If they stay at 50%, or out of balance but still cumulating to 100%you ar not hyperthreading.

/txtmngr/images/smileys/smiley4.GifThank you for the Device Manager tip !

I had an old AOL Optimized PC with a 2GHz Celeron & 400 MHz FSB.  Now running a 3.06GHz Pentium with 533 MHz FSB and hyperthreading ($35 on Ebay). Don't really care if the HT doesn't really help, at least now I can pretend I'm not using such an old piece of junk.

Enabling Hyperthreading - how do you do it?Enabling Hyperthreading

With XP and later (and maybe Win2000) Ctrl+Shift+Esc gets you to the Task Manager faster than Ctrl+Alt+Del.
