Is WindowsXP required to run a hyper threading CPU?

    I’m still running Win98SE. Yeah….I know...I know..... I am considering upgrading my P4 1.8A to something faster. Will I have to upgrade my OS as well? Was o/c-ing the 1.8 to 2.4 but it’s not completely stable. My m/b is a Gigabyte GA-8IEXP (ver 2.0) which has the 845E chipset and 400/533 FSB support. Also, running Crucial DDR PC2700 512MB memory. The Gigabyte website says the m/b supports the P4-Northwood 3.06G (533FSB) Hyper Threading CPU. I don’t do a lot of multitasking, but I do a lot a CD burning and game playing. Would this upgrade be possible or worth the dough? Really not interested in upgrading my OS or m/b. Just looking for a quick and cheap CPU upgrade with bang for the buck! Any feedback would be appreciated!

    The CPU will still run.

    But you will not get Hyperthreading support without Windows XP, Windows Server 2003, etc.

    BTW, the impact on CD Burning is 0. The impact on games is mixed.

    I'd still upgrade to XP as 98SE is very dated [​IMG]

    Chris: Thought I read XP was required. I just don't keep up with PC hardware the way I used to. Man...I used to have it bad, was O/C-ing even before the Celeron 300a@450 was popular. Ya' know, come to think of it, I don't think I've spent a dime on my PC since I started seriously upgrading my HT a couple of years ago. Anyway, that's exactly what I needed to know. Thanks Chris!

    More importantly, unless something has changed recently you need Windows XP Professional to get hyperthreading. Windows XP Home does not support hyperthreading.

    My error. I know I read it once and it appears that, according to the articles you linked, there was some misinformation. Glad to hear that isn't the case.

    Hyperhtreading really shows it's stuff when your doing multiple things. Burning a CD while surfing the net and running a media player all at the same time for example. Hyper-threading basically lets the OS make real use out the spare processor cycles.

    True, but on the other hand, in some benchmarks, HT can slow you down as well.

    HT makes -some- difference, but it doesn't make a night and day difference, and in many cases, it makes very very little difference.

    Does 2000 support hyperthreading? My 2000 box shows it as dual processing in the hardware settings, and software like Tmpgenc detects as hyperthreading- so am I not getting actual horsepower out of it?

    Supposedly not. Open up the Task Manager (right-click the Task Bar). On the Performance page, do you have two CPU graphs?

    Windows 2000 will think a hyperthreading processor is two physical processors. I don't know the full explanation but hyperthreading is not recommended for Windows 2000.

    That's correct. XP understands the difference between separate logical processors (hyperthreading) and separate physical processors. 2000 does not. In some instances, you may see a performance boost with hyperthreading enabled in 2000, but because the thread scheduler thinks that 2 CPUs are installed, you may run into performance hits. Intel recommends disabling hyperthreading on Windows 2000.
