    Hiii experts pls tell me how to overclock my intel e5300 in step by step as this is my first oc'ing.
    My config mobo-asus p5kpl-am/ps
    cpu-e5300
    ram-2*1 gb ddr2 800mhz
    hd-seagate 320gb
    smps-zebronics 450 watt.

    Go to bios, disable speed step, increase FSB by 10

    Start windows check CPUz

    Run Prime95 for stability..

    ^^wt happens if u overclock without disabling speed step in intel systems?

    Background:

    This is an old technology. It was initially deployed on the laptops to increase the battery life. The CPU chews up a major chunk of the battery draw (sorry GPU owners). It was then adapted to suit desktop CPUs and also made standard for the same.

    What it is:

    When the system is being used less (i.e. the CPU) the base multiplier is automatically lowered. This causes the clock speed to come down. (clock speed = FSB x multiplier). So when this happens, the CPU takes less power. And thus is more efficient.

    OC without Disabling Speed step:

    The reason we disable this feature, cause we are now manually setting / modifying the multiplier (and FSB), but if Speed step is also doing this dynamically, then we will never be sure what is correct. Is our manual setting working, or is speed step working.

    ^Is it possible to re-enable speed step after we reach desired overclock?, such that processor will only work at overclocked speed when needed?

    Great question...!

    Ideally you should be able to do it. But think about it. You want the system to run at a certain speed (your OC setting), and with Speed On (SS), they system takes over. So at times it might not give you the OC speed. And since the SS will also change the vCore, you might get stability problems. But nevertheless excellent question. I always leave it off.

    UPDATE:

    Read a few forums. People have successfully continued with SS on after OC setting are complete. It is a mixed bunch. You could try it, once you have stable OC.

    This mobo does not have much of overclock features. U can just get ur RAM to run at 533MHz and increase the FSB to ~290 but reach there in steps not at once.

    As far as i remember, i used to run my E5200 at 3.7GHz with speedstep enabled. So shouldn't be an issue.
    But ya, i did it with a SCCF, so if you are using a normal CPU cooler, keep an eye on temps and don't exceed 60 on load.

    Run stress tests like OCCT after every increase in FSB. Try incrementing the FSB in steps of 10 or 15 to be on the safer side. If stress tests fail in 10 minutes, go back to earlier FSB. Dats how you do it. :hap2:

    You must have had SS disabled, while doing the actual OC..? Also the OP can push in slight increments of extra vCore to keep the OC working...

    Yes, i had speedstep disabled while doing the OC. :)

    You need not increase the vcore unless the system becomes unstable. Its like putting in more voltage when it is not needed which might increase temps and power consumption while giving no extra benefit et all. :cool2:

    So, OC with default vcore until the stress tests fail. Then increment voltage and increase overclock. :)

    Yes, what you said makes sense. But many times motherboards come out of the box, with really high vCore set. Like mine came set at 1.4v for some reason. So I lowered mine to the absolute minimal the system could run at --- at stock, then started the OC. Of course only when unstable, and more juice is required, then push in more vCore.

    Though there is another school of thought. Many straight away push in 1.4v reach their desired OC, then start to lower.
