Hello i got i3 530 and just bought gtx 660
i think its bottlenecking because in bf3 i got big fps drops
so i want to overclock the cpu.
i never overclocked anything before i am new in this
Compuer specs :
4 ram
chiftec 550W
GTx 660 gigabye 2gb oc edition
i3 530
motherbaord : Asus p7h55-m lx
i went into my bios and i think my cpu locked or my motherbord is this possible , can i get tutorial to overclock my cpu?
thanks.

I looked at the manual for your board and it wasn't clear if there were any overclocking options for that board. You might be better off upgrading your cpu. Given the age of the system, it is possible a new board and CPU would be the best option unless you can pick up an 1156 i5 quad or i7 really cheap.

You need a P55 chipset board to do any sort of overclocking.
You ALSO need a CPU cooler.

So in short, you can not OC.
Nor would OCing that CPU help much, BF3 multiplayer needs quad core tech to not drop FPS.

What you basically need to do is raise the FSB / BCLK from default 133MHz to whatever you want, whilst keeping the memory at its rated frequency.

i3-530 (2.93GHz) = 133MHz(default FSB) x 22 (default CPU multipler). If you raise FSB to 166MHz, then you'll get a 3.65GHz CPU.

However, raising the FSB also raises the memory frequency. So you need to make sure that your memory can cope. You can do this by adjusting the memory multipliers (depends on your board but my old one had 6x, 8x & 10x (default) IIRC). Memory multiplier of 10 x 133 (default) = 1333Mhz. If you have a 1666MHz memory chip, you can raise it to 166 FSB x 10 (mem mult). If not, then you'll have to select the next lowest memory multipler, eg, 8 so you'll get 166x 8 = 1,328 MHz.

If you raise FSB to say 182MHz (x22), you'll get a 4GHz i3 - but then your memory will be overclocked and probably unstable - just move the memory multiplier down a notch again. If you have 1333MHz memory, you can use 6x and if you have 1666MHz, you can use 8x. Although this will result in slightly underclocked memory, you can compensate for that by lowering the CAS too (say from 9 to 8).

What you basically do is keep upping the FSB then check stability, then upp it some more, then check stability (Prime, etc), whilst making sure the memory stays roughly near or below its rated frequency. As you get past 3.6GHz, you may need to upp the CPU's VCore slightly. On my old i3-530, I could get it to 3.9GHz on stock voltage, and 4.2GHz with +0.1v. All CPU's are different though.

These might be of some use:-

and i dont see its saying overclock is possible :( 
also in bios i dont see option to change fsb and clock speed

Hmm. Doesn't look like you can do it on that "LX" board after all. That's odd as I had a Gigabyte H55M board that could. That's a shame. Looks like an upgrade is in order.

i managed to raise the fsb to 166mhz so my question now did i overclocked my cpu?
i need to do more changes ?
thanks for help btw

Download CPU-Z and see what "Core Speed" says in Windows. At 166Mhz FSB, it should be "3652 MHz". If so, then you've just gained a 25% boost. You could always gradually raise it higher. Many i3-530's have no problem doing 3.9-4.0GHz. Which would be a 35% boost. Make sure to run a stability testing problem like Prime or Intel Burn Test. If it crashes, either reduce the frequency slightly or upp the voltage slightly.

overclocking shouldn't be too much of a hassle given the right mobo - remember having one of the clarkdale i3's (550 i think) was a breeze to get it to 4.2 even with a relatively low-end msi H55M-ED55 mobo & a cheapo coolermaster hyper tx3. There's plenty of well-written guides to overclocking the lga 1156 cpu's out there, just be wary that unlike it's i5/i7 brothers, it was built on a 32nm process (the same process used in hex-core westmere-ep cpu's & later sandy bridge) so will be more sensitive to voltage. only very fine adjustments & amounts should be needed. http://www.tomshardware.com/reviews/core-i3-530-overclo...
