    Down .05 will be enough That should allow a much better thermal and it should'nt change the overclock. You should stil be able to boot up @ 3.8Ghz with the vcore at 1.25 If for some reason as in overclock, memory, ect. it won't boot into windows restart go back into bios and set the vcore up a bit. But if your cpu vcore is set to auto in bios, then you wont be able to drop vcore voltage any. You will need to reduce the multiplier, or bus speed or memory timings or memory voltage. For a good thermal cpu and system. Many options are in the cmos setup for that board.

    Mad Hatter I noticed that Gigabyte has bios updates for the board and cpu you have. F6 2009/03/31 has Enhance Core i7 D0 stepping compatibility
    and Fixes abnormal messages from EasyTune 6 and DES in Vista. Also F7 2009/05/11 Update for new CPU microcode
    What version of bios does your motherboard have? Here is the web page you can download bios updates for your motherboard If you don't have F6 or F7 than this is more than likely your computers heat issues. Go to the bottom of the page----> http://www.gigabyte.us/Support/Mothe...ProductID=2961 Download this english version from (Asia)China It's a faster download. When done your board will be at original settings and you will need to reset your overclock. You may want to go into bios first and write the cpu clock ratio and bus frequencies and memory bus frequencies, and timings down so you can set them to the new bios.. If it were me I would. Thats if you don't have the F6 or F7 bios.

    Ahoy,
    Ok i lowered the Vcore voltage is CMOS to 1.25XXX. System took abit longer to boot but im sure that isnt anything to do with this. CPU is currently 35c and the system is 41c and its very warm in this room, the CPU seems to be idling around 35/37c which as far as im concerned is a good step forward. I havent reapplied the CPU heat sink yet, mainly because i cant find my rubbing alcohol. Im hoping that when my extra long 3 pin fan cable turns up i might be able to get some more air flowing through it. Im also going to set the CPU fan to 100%, instead of being smart managed. With all the fans in this thing, it was never going to be a quite pc. I shall run prime95 torture test again tonight and will let you know what happens, as long as the alarms arnt going in the morning (and the thing hasnt crashed) then i shall be very happy.
    So thank you all who have helped, especially you Artdrivers. I shall post again tomorrow.

    Many thanks
    Mad_Hatter

    I am glad to see the improvement, and your welcome. Do you have the F6 or F7 bios? I saw somewhere you should only run prime95 torture test for 10min. Looks alot better already

    No idea what bios i have, shall check on that shortly.Prime95 for 10mins? Piff and pure nonsense, this system in its old 'oven' state managed 8hours 55mins (though all alarms were going). First thing i did with this system when i built it was to write down all the bios details in the motherboard manual, had to format a bios for an old system of mine and i was never able to get it to the same speeds again. Also just ran prime95 for about 3 mins and it got to 50c so its looking promising. I have to ask, what temps should i be aiming for with the CPU? As 36c is cooler than my old liquid cooled Q6600 system (overclocked to 3.6ghz). Oh and i have also turned on CPU throttling under heat in the bios (dont know its name, lowers voltage and power when the CPU gets to hot) and set SensorsView Pro to shut down the system at 75c, so i have a good few fail safes.

    Yeah D0 stepping should run cooler than C0 because you can keep lower volts like artdrivers was saying.

    10 min? That hardly seems long enough to catch stability issues. I have had Prime95 errors creep up after over 6 hours. As the system becomes more stable the chance for an error decreases significantly but its still there. Even a stable system at stock settings will EVENTUALLY give an error. Stability is not really a yes/no, its how long can you last. I guess if you don't do hardcore computation or gaming for long continuous blocks of time, then you can deal with a higher chance of errors.

    Personally I start Prime 95 blend mode and then immediately start Intel Burn test and let them both run for at least 12-16hours. Then I know when I'm doing heavy video encoding or gaming for many hours straight the chance of something going wrong is low.

    Same here Demonsavatar, my view has always been, if it can last over 10 hours under stress with no errors, then it can handle anything im ever going to throw at it, which is mostly gaming and a tiny bit of video encoding and editing.

    That 10 min was for initial overclock at Toms hardware. You are correct that wont test any stability issues where you alot of computations for long periods of time. But I also know that many cpu's have been sent to intels RMA department due to failure after a couple of months of overclocking use. I would want to avoid that.

    Well *touches wood* my last 4 pcs have all been overclocked and all torture tested, some for over 2 days and so far i have been able to sell / give away all but my last one.... which caught fire when the liquid cooling CPU block leaked all over the motherboard and fried it... hence air cooling for this one...that and i was fed up with replacing pumps at 20 a time.
    Also dont CPUs now have an expected life expectancy of something really stupid like 10-15 years under normal use? I know hard drives now have something similar. As i never plan to keep a pc for that long, id rather push it harder and get more out of it.
