Hi,

The other day I purchased a Pentium 4 3.0ghz Socket-478 800FSB. I have a SIS661fx Northbridge chipset and SIS946 Southbridge Chipset (I think). Anyway I have set hyper threading as enabled in the BIOS and when I run the Intel Hyper Threading test the proccesor passes, the bios passes but the Chipset doesnt. I have read over the internet and on the SIS site and they say the SIS661FX Chipset is Hyper Threading Supported. How do I enable Hyper Threading on this chipset? I have downloaded IDE drivers for it but no prevail. Any software I have to install?

Thanks,

Jeremy Dey

What manufacturer and model motherboard do you have?  If you are running Win2K or WinXP, do you see two windows in the performance tab of task manager?  That would be to me an indication of hyperthreading being enabled.

Hi,

Yes I own a Acer Computer. I don't know the motherboard model number but I do see two windows in the performance tab.

Then you don't have to worry about hyperthreading - it's working.  Try running a cpu-intensive task and you will see task manager hit 50% (instead of 100%).

At one time I saw it go over 50 though and reach 60.

That might  have been the rare case where both threads were being used simultaneously, which is what it is designed to do.
