2550k + Gigabyte z68x-ud3h-b3 Can i overclock it with just....

i dont know about the oc but dont mess with the pcie frequency, it will fry your card
dont use stock cooler to oc
if you dont want to adjust voltages then dont overclock..?

If you want to OC buy an aftermarket cpu cooler(air/liquuid) You can overclock the cpu by increasing the cpu ratio multiplier and also invreasing the cpu vcore not more than 1.35V. Let the dram(memory voltage) voltage set to auto. Download and run cpu-z and hw monitor in cpuid.com to monitor entire system and the core temps of the cpu. down load and run wPrime and or prime95 one at a time for about a minimum of 2 hrs, and if the system does not crashed, then your oc'd cpu is somewhat stable. While running the wprime or prime 95 you have to run also cpu-z and hw monitor to monitor the system and the core temps. Temps should not be higher than 75 deg Celsius, higher than 75 deg is dangerous to the CPU and will shorten the life of it. Don't hesitate to buy a CPU cooler because it's a good investment to prolong the life of an O'Cd CPU.

You can overclock a 2550k to 4.0GHz easily on a stock cooler.
Use the bios not Easytune and stock voltage.

my temps in windows are now arround 27-30 degrees celcius,

so if i get u straight, i dont need to set my pcie freq to manual? back in the day when adding up the multiplyer it would automaticly do so for your pcie

and i can leave my ram timings as it is on auto ?

and my final question ,

doing so will only overclock my pcu in turbo mode (wich is ok with me)

then i can just do the multiplyer and it will say in windows 3,4 ghz ( 4 ghz) under stress it will go to 4 ghz?

ill do this is ur sure , if ur sure im sure  

Here a link to a guide used for overclocking sandy bridge CPU on gigabyte boards.

To answer you questions. You don't need to mesh around with you ram, more like you shouldn't until after your OC CPU.

Make sure to enable Real Time Ratio Change in OS and Turbo Mode if you don't want to have it running at 4 GHz all the time.

ive read it before , the thing is .

whats wrong with just upping the multiplyer .
i have done that now ,

my multiplyer changes all the time in cpu-z . depends on the cpu usage .

now i put it to 4 ghz , so in My computer is shows

3,4ghz 4ghz (being turbo mode)

i left every other setting in the bios as it was ram voltages everything just the multiplyer .

this seems to work when is tress my cpu it goes beyond 3.8(the normal turbo mode)

this is what i wanted nothing more.

will this result in damagE?
so yes

how ?

At this moment right now im playing battlefield 3 , the multiplyer is 40x and its using 4 ghz when i play, when i quit it goes back to 3,4ghz or even lower

i didnt change ANYthing in the bios but the multiplyer do u understand me?

tell me what i did wrong

Ok overclocking my pc made it go all messed up,

there are a few things i do not understand from the tutorial u sent me , first of all.

what is a retail cpu ?. i have a 2550k

Make sure you DISABLE all of the following advanced CPU features (to stabilize multiplier and voltage):
C1E-DISABLE (With some boards like ASUS please keep C1E, EIST, and C3/C6 enabled at the moment, MSI and Intel boards you can turn these things off, but I am guessing Asrock will need it on as well)
EIST-DISABLE
C3, C6 States-DISABLE
CPU Thermal Monitor-DISABLE

Do not touch BLCK right now as it always needs to be lowered as you overclock higher, at stock or low OC (under 4.3 GHz you can increase BLCK no problem). Make sure you make note of Stock VID/Vcore/VCC (found under voltage options). Upon reboot if the system boots into BIOS check the new VID under voltages settings or CPU Vcore (VCC) under health monitoring, take this value and compare it to this:

Stock-4GHz on Stock VID
4.0-4.3GHz 1.300v-1.325v
4.3-4.5GHz 1.325v-1.375v
4.5-4.8GHz 1.375v-1.450v

i cant find these settings eather in my bios

This thread is done, i have finally gotten the awnsers i need,

It is not possible to overclock just the multipplyer , the vcore will go along with it and overburn ur cpu thats all i needed to know thank you
