hyper-threading

descalle — Sun, 27 Mar 2005 06:45:56 GMT

hi,
i just have a PCG-K415S notebook whit a P4 532 533Mhz frontside bus processor,and when i read the cpu specification paper that came whith the vaio :
support Enhanced intel SpeedStep Technology and Hyper-Threading
Now the problem is that when i run PCMARK ( pc performance Analysis) it sais that Hyper-Threading is Available but Disabled !

Is there a way to check that hyper-threaing is enabled in win XP home with sp2 ?

Thnx and regards

Does the "intel inside" sticker on the laptop have a small HT on the right hand side? See
here.

Some processors which are HT-enabled dont have the benefits of HT technology because you also need a compatible motherboard/chipset. This may only need a BIOS upgrade.

When HT is enabled the device manager should show 2 processors.:smileygrin: :smileygrin:

Interestingly, Sony said in my info sheet with the K115Z that it has enhanced speedstep -well it doesnt and never will have. It only has Speedstep, so I think they are confused...

The difference is with enhanced speedstep the processor voltage and frequency change across a wide range, while speedstep simply changes the frequency from 3.06Ghz to 1.6GHz only.

It looks like the PC doesn't have HT.
PCMark usually is very accurate.

I would have a word with Sony, as it's been sold to you under the wrong pretence.

Kee-Lo the "PCMark usually is very accurate" I know for a fact that some Toshiba laptops have HT BUT the sticker was a normal one and have also seen this on my mates one. The best way to check is to press ctrl and alt and del until the task manager is poped up then click on the performance tab and if you see two process then it has HT. like mention already

if you see two process then it has HT

Do you mean the two boxes under CPU usage history?

Jep, that is HT.

But you can't compare this with a real Dual CPU system.:smileycool:
