Hi

Here s my specs:

Gigabyte GA-P35 DS3L
Intel E6550 2.33 Ghz (Stock cooler)
2x1 gb Kingston 800Mhz + 1x2 gb Corsair 800Mhz (Total: 4gb)
Sapphire HD 5830 Extreme
Seagate 320 GB
Feel Hurricane
FSB Bluestorm II 500W


I want to OC my E6550 but i have no exprience about overclocking. I searched e6550 OC a lot but cant find similiar to my specs.

How far can i go with these specs? and Is there anyone help me step by step?

I am reading the manual of your mobo. If u want to OC with just the stock cooler, DON'T push too hard. And first plz turn off some power-saving features CPU Enhance Halt and CPU EIST Function (if there were enabled, both are in Advance BIOS Features).

Disable CPU Smart Fan Control (in PC Health Setting) to gain full cooling if u don't mind the noise.

You are multiplier up locked so you can only go faster by increasing the FSB. If none of that made sense to you then you need to do more reading/research. You have a good board and a decent chip, but that stock HSF is going to hold you back. I think your stock FSB is 333MHz. Try to slowly raise it by five or ten MHz and see how stable it is. Whatever you do don't raise the Vcore.

bah..check your temps with realtemp;If they're OK,feel free to add some vcore.
a)lower RAM speed
b) raise fsb
Not sure if this will help any but..It should give you an idea what it can do.

One thing I know about 775 on Giga..If one RAM strap doesn't work.. try the next letter
Conroes like 75% of all the fsb voltage you can give,Wolfdales like 100%
juice the nb voltage

It turns out to me that the FSB tweaking is a good solution. But if it is raised to a limit (say 360Mhz 'cause it will raise to 2.5Ghz) and if your system is unstable, tweak some CPU voltage up (but very carefully, 0.0125V each time) to secure your achievement. If u could boot your system by 400Mhz FSB, set FSB & DRAM ratio to 1:1 if u use a ddr2-800 memory. (if less than 400 FSB don't set the ratio)

I would set the ratio to 1:1 anyways. Even if you hit 360FSB, your ram will be at 720 which isn't far off of 800MHz anyways. It's slightly better to set it to 1:1 as you wont' have to worry about what your ram is running at now, it's always double the FSB. If you are running 2:3, or 4:5, it can take a bit to figure out if you have OC'd the ram. This does assume you have DDR2-800MHz because if you have DDR2-667 and you try to hit 360/720MHz your ram might have issues.

nd if your system is unstable, tweak some CPU voltage up (but very carefully, 0.0125V each time)

Honestly on a stock cooler I wouldn't up the Vcore at all. They can barely handle the heat the stock chip puts out, upping the Vcore is only asking for trouble. Buy the 212+/evo and don't worry about the problems with the stock cooler.

As i said im really a beginner for overclocling

there are my current bios settings:

now how should i start which values should i change?

Seems that u haven't turn off some power-saving functions(CPU Enhance Halt ,CPU EIST Function and CPU Smart Fan Control ) . That may affect your OC.

What @4745454b told u is that to enable CPU Host Control and tweak up the Host Freq. by 10 or 15 Mhz. Set PCI Freq. to only 100 Mhz if available.

Tweak your Vcore by .0125v each time if u find it unstable when the Host freq is tweaked up a little bit.

As I said, if you are this new you should be reading more. You need to know what EACH one of those values mean so you don't accidentally hurt your computer.

Seeing as you are just going to ignore me, the FSB adjustment is probably under CPU host clock control. Set that to enabled. After that you can probably change the 333MHz value. I'd start with 340 and see if you are stable. If you don't understand what the means this is more proof you need to read more before you do this! You'll need to change the System Memory Multiplier off of auto and set it at...I'm not sure what values you have there. Read the manual or play with it some.

From the last screen none of that pertains to OCing. It was suggested to turn off C1E and EIST. You should probably do that while testing the OC so you don't get any funny values. But once you have your OC you should probably turn them back on so that you can save a bit on temps/electrical use.

From the second screen I would enable the temp and fan warnings. You want to know if things are getting out of hand. Notice also that before you are stressing your CPU your stock fan is already allowing the CPU temp up to the mid 40c. You don't have a lot of temp room here.
