    Ok so I have an i73820 non K/X version of it so I know its locked for overclocking but after digging iv read these a way to but as iv tried I can get a stable OC the cpu I have now is the i73820 3.6 when I originally had it in my alienware comps old mobo it was clocked at 4.2 from the factory since then I have bought a different mobo brand for my comp for more reliability and want to get the cpu back to a stable 4.2 or better with low temps and im at a loss pls help I would really love this thing running like before

    Hi JP

    The 3820 can OC two ways....you can just increase multiplier up to 43 so 42x100 will give you 4,2GHz or you can change the base clock by using a "strap" of 125....so instead of the multiplier being multiplied by 100 it is multiplied by 125...this is usually for higher overclocks.

    If you are happy with 4,2 or 4,3 it should be as simple as setting multiplier to 42...43...

    Hey Arne

    thanks for the reply ok gotcha so lets say I wanted to go a bit higher with the strap method what should I do to achieve that I'm not sure if my ram can handle it or not thought I would ask before frying it. :P

    You won't fry it...no worries there...it might not boot but then clear CMOS and start again...

    72C at max load (prime) isn't so bad… you won't likely use any applications which would stress that CPU so much… - but I would not raise the Vcore more than you have it now…

    If that speed (4.2) is enough for you, you could try to lower the Vcore notch by notch until it won't boot and/or won't pass your prime… maybe you could save some more in temps...

    You're right to keep an eye on temps of course. 75 or 80 is a good ceiling. One thing...if you overclock with 125 strap you can't take advantage of speedstep...if you use 100 blck you can so if you go for 4.2 4.3 I would stay at normal strap and bclk. Speedstep lowers clocks and voltage when the processor is idle...a good thing... Try some manual voltages....reducing bit by bit...auto voltage often uses more than you need...if you find a stable manual voltage we can find a good ofset voltage and have lower vcore and speedstep at the same time...

    Temps are looking fine!

    One comment though... be careful with AiSuite installed and any other application (Core Temp in this case) which is reading the same sensors... - it may cause crashes later on... but as of now, it seems good...

    Try to use the system for whatever you have built it (your regular applications) and see where the temps will go, and also if the system is stable enough too...
