    Default CPU Multi Threading & Overclocking (beginner alert)

    I've fumbled my way through an i7 920 4.01GHz overclock & it isn't yet stable (blue screens after 4/5 passes of IBT on high) but it's progress as I couldn't get it to boot into windows for quite some time.. anyway

    I've been told that I have a better chance of stability & lower temps (they were a little high during the IBT test peaking at 85/86c & I have a Noctua NH-D14 & some very good case fans) if I use a 19x multiplier instead of the 21x I'm currently using it's also been mentioned that turning off the CPU multi-threading option will be very helpful in reducing temps & have little or no effect on game performance (the main reason for the overclock)

    Any input would be greatly appreciated

    Thanks.

    Other then getting better cooling the only way to reduce heat with out reducing cpu speed would be to disable HT dropping cpu multi will only reduce cpu speed.

    Now if you were only shooting for 4.0ghz then yes you could drop cpu multi and then up the bclk again to match the 4.0ghz speed.

    If your hitting 85-86c at full load with ht on I would guess disabling HT would drop temps to around 70ish. Also note that disabling HT will also allow you to reduce vcore as its not tring to push 8cores only 4.

    What BSOD are you getting. You can get a list of BSOD error codes and their corrections form the link in my sig.

    Also what motherboard bios are you using. If you could fill out your sig with your current hardware we would could better help you out.

    Thanks for the answer..

    4.2GHz would be the ideal but I would be happy with a stable 4Ghz that doesn't have temps like the surface of the sun, I'm certain that I don't have a HT option I can't see it anywhere in the bios (I can see CPU Multi-Threading however) as far as the BSOD errors I don't know, but I will be running some more IBT tests this eve so if you are still around later I will post back.
    How do I find out what bios I have..? (I inherited the rig & haven't really changed anything)

    Cpu mutli threading would be it. Intel calls it HT Hyper Threading.

    As for the bios version this should flash on the screen doring boot up or when your in the bios you should be able to press a key and it should show you. On Gigabyte boards your press F9 and it will show you. If you still cant find it in the bios you can run CPU-Z in windows and click on the "Mainboard" tab and it will show you motherboard model and bios version.
