    my new system specs and i need help of mild OC

    EP45C-DS3R(F5) / Q9450 / 1gbx4 G.Skill PC2-8500 / HD4850 / 320gbx2 Seagate RAID0 / Tt ToughPower 600w.

    currently i only adjusted the RAM timings to 55515 @ 1066 and still running stock on my CPU, and i want at least lil OC ;)

    tnx!

    How much do you know about overclocking? Have you read the sticky?


    Also try reading this:

    Overclocking basics

    The most basic thing that you need to know is that you increase the FSB to increase the CPU speed. RAM speed is linked to the FSB though by a factor that is adjustable so you will need adjust that factor as well. Additionally, you will need to increase voltages.


    If you don’t know what the FSB, the multiplier and effective and real FSB and RAM speeds are read the following bit:

    Let’s start with definitions of the settings that you need to change.


    The CPU speed is derived from the FSB multiplied by…. the multiplier!

    FSB (Front Side Bus): The connection of the CPU to the northbridge*, usually 200, 266 or 333 MHz for current Intel CPUs. As four bits of data are transferred every clock cycle (i.e. every Mhz), Intel markets these as 800, 1066 and 1333 respectively because of that. These higher frequencies are also often referred to as the effective FSB.
    The FSB can be adjusted upwards and downwards and is only limited by how much the motherboard and CPU are capable off.
    * chip on your mainboard connecting the CPU to everything else, a higher FSB means more bandwidth and is therefore better for performance

    Multiplier: This is locked and can only be decreased but not increased to a setting higher than the stock value. The difference between an E8400 and an E8600 CPU for example is the stock multiplier of 9 for the E8400 (resulting in 333 x9 = 3.0GHz) and 10 for the E8600 ( 333 x10 = 3.33GHz)
    Because the multiplier is locked on all CPUs but the Extreme Edition CPUs you can only overclock your CPU by increasing the FSB.
    The multiplier is called “CPU ratio setting” on Asus boards.

    RAM: DDR RAM (no matter whether DDR1, DDR2 or DDR3) actually runs at half the speed it’s quoted at (i.e. 333 MHz for DDR2 667, 400 MHz for DDR2 800, 533 MHz for DDR2 1066 etc.). As it transfers two bits of data per clockcycle these higher effective frequencies are commonly used though.
    RAM is backwards compatible, meaning that you can always run faster RAM at a slower speed (e.g. 1066 RAM at 800 or lower) but also faster, RAM can be overclocked like the CPU itself.
    Relationship between RAM and FSB speed
    The important thing about RAM when overclocking is that it needs to be able to run at least as fast as the speed of your FSB (I’m talking about the real MHz, not the effective values). So if you want to overclock your E8400 to 4.5 GHz (500 x9 = 4.5GHz which would be high but is possible) you would need RAM capable of running at 500 MHz (DDR2 1000) so you should get DDR2 1000 or better RAM.
    You can also run RAM at a higher speed than the FSB, there’s a setting called “system memory multiplier” on Gigabyte boards in the BIOS for that. If you have a FSB 333 MHz CPU (1333 quad-pumped) and DDR2 800 (400 MHz) your BIOS will likely automatically cause it to run at DDR2 800 which is the 2.4 system memory multiplier (333 x 2.4 = 800). If you increase the FSB to 400 now, RAM speed will also increase to 400 x 2.4 = 960! To prevent that you can change the system memory multiplier to 2.0 and have the RAM running at DDR2 800. Remember to alwys check the system memory multiplier when changing the FSB!

    The A, B, C, D at the end of the system memory multiplier indicate at which FSB the multipliers should be used. Always take the one closest to your FSB, rounding up.

    So for starters, set the FSB to 400, the system memory multiplier to 2.0D and CPU VCore to 1.325V and see if that is stable.

    tnx for the quick reply

    simple 3ghz only and i want is fitted on my system specs, no more trial, just a 24/7 3ghz.

    thanks again

    My settings will get you 3.2GHz as the multi of your CPU is 8. If you want to you can decrease the FSB so you only hit 3GHz.

    3.2ghz no problem, but how about the rest, Advance settings etc. after changing the FSB.
