Problem with Hyper-Threading

Rambotnic · Jan 12, 2007

Hello, it´s been a while since I last visited this forum, but something is bothering me. I downloaded "Hyper-Threading Technology Test Utility" from Intel´s homepage and ran it(I was simply bored :ohwell:

). The results differed from what I expected:

Although Everest and everything else point to that I have 2 virtual cpu units, this test utility says that my chipset and bios have problems with HT. I have attached my computer information and the test results to this post.

If If someone has encountered the same problem or has a simple explenation for this matter, then please help.

you must make sure hyperthreading is enabled in the bios..

Did you install the Intel chipset drivers? (inf utility) I don't know how the check tool reads the info but it might be dependent on the drivers.

Rambotnic · Jan 12, 2007

In BIOS I had the HT option at auto(it only offered auto or disabled).

Do I need it even if have VIA chipset?

No, you need the 4in1 or Hyperion drivers for VIA, or whatever VIA calls them nowadays.

Rambotnic · Jan 12, 2007

I have them installed. But if everest shows that I have HT working, do I really have any reason to worry?

Check the task manager, if it shows 2 graphs for CPU usage it's working.

Rambotnic · Jan 12, 2007

Yup, it seems to be working, thank you

!
I think its my crappy mobo that caused this misunderstanding.

I'm sure it's related to the VIA chipset.... One other way for reality check is open task manager:

Look at the performance tab where you see the two virtual CPU useage graphs
Run Prime95 - one of the CPUS should be near 100%, the other near idle
Run SuperPi while Prime95 is running - now both CPUs should be near 100%
... great stress test too!

That's how my 865 and 915 intel chipsets and Northwood/Prescott behaved.

cheers

Why Prime95 and SuperPI, why not 2 instances of the same program?

Honestly, I've never figured out how to run two instances of Prime95... any hints?

Also, when running the two together, I've had one or the other fail and one still running - leads me to believe there's more silicon coverage.

Ok, I tried running the Prime95 and although the graphs differed from eachother, they both wondered around 60%.

Also I tried Systool-s PI calculation test(2 parallel tests) and the performance was better with HT enabled in BIOS, so it must be working.

Sasqui · Jan 13, 2007

Hmmm... I just started running it now on my Core2, and it's about 60%/30% between cores (SMP)... I remember on my 630 Prescott seeing one at close to 100% and the other around 0% (w/ HT) - maybe the VIA handles it differently.

DantheBJm has me wondering about running Prime95 twice at the same time - will he answer?

Rambotnic · Jan 13, 2007

Maybe he used different versions.

The test requires you to have an intel chipset to pass. Since you have a VIA chipset it's failing you.

Thank you, and sorry for cauzing so much buzz from nothing

Just make a copy of the extracted Prime95 folder, name it something different, then run 1 instance from each folder.

No worries, it was a good question.
