    Hi all,
    I was just putting my 40gig storage HDD back into my pc and I was browsing in the bios and I saw that HyperThreading Transport was disabled. I know what it means but is it usefull? I use my PC mostly for gaming. Proc. specs:


    Intel Pentium 4, 3215 MHz (16 x 201)

    Northwood HyperThreading

    D1
    x86, MMX, SSE, SSE2.

    L1 Trace Cache: 12K Instructions
    L1 Data Cache: 8KB
    L2 Cache: 512LB (On-Die, ECC, ATC, Full-Speed)

    on Socket 478

    Should be enough I hope.

    [offtopic]
    Just a quick other question, would it be usefull to OC my system to 3.8 and the ram to 200mhz (pc2700@166mhz it is now) Will it give me more FPS in 1024x768?[/offtopic]

    Deva :)

    for soem things yes for others no. hyperthreading logically splits the CPU into 2 parts and it's supposed to help with multitasking and certain multithreaded applications. However as implemented on P4s it slightly slows down a few thigns(fraction fo a percent) for the sake fo it though, turn it on, it's more helpful than detrimental. Now HT on something with a shorter pipelines is a diferent story... far more effective...

    yes... I skimmed DFI's forum as well apparently it's a common issue for something to not be able to boot up for a few times... turnign it on and off fixed it.

    I have HT on my processor (P4 3.0 GHz) and if I have it turned off things are alot slower, so I just keep it turned on. Intel claims that it makes your processor 30% faster. I found that it helps even in games and alot with multitasking.

    30% is bull ----. it makes some thngs slower in reality(fraction of a percent), the only things HT really improves on are highly multithreaded. it helps more than it hurts though. and yes, it should help while gaming as it would help compensate for interuptions(EG: virus scan at 2am etc.)


    after neabling it thuogh, hwo many cores does ctrl+alt+del recognize? it should show two line charts for CPU useage, otehrwise it's not working, check and verify that it has two charts.

    Yes, it does show 2 cores, on several programs.
