i5 2500K problems please help a newbie

post #1 of 3
Thread Starter 
right i just built my new rig and it cost me a pretty penny :-

COOLERMASTER HAF X
ASUS P8Z68-V
i5 2500K
Antec Kühler H2O 620
Corsair Vengeance Jet Black 1600 DDR3 8GB
Corsair Force Series 3 120GB SSD
Western Digital 2TB Caviar Green
VTX 2GB RADEON HD 6950
Powercool 850w Modular
200mm red led coolermaster fan x 3 and 2 x Akasa 120mm fan
Windows 7 Home SP1

right, when i use the asus ai suit it just messes up, when i try to OC manually it is never stable - I did manage to get 1 stable setting (thanks to the help of a friend) at 4.9Mhz - see pics.




but for some reason since we tried to make the system run at 4.9 when under load and idle at 1.6 instead of staying at 4.9 it kind of went ..... erm.... wrong and hasn't worked properly since.

we have reset back to standard and tried again but any time we get close it just blue screens on us.

what we did in the bios (uefi) on the asus p8Z68-v in advanced mode, we enabled manual mode and had it set to 100mhz and a multiplier of 49, diosabled power saving increased the CPU voltage to 1.475v (ish) changed the long and short term thingy to 230 , apll voltage to 1.9 vcore ofsett of 0.052, disabled speed step, spread spectrum, c1e1 and some other things, but have not been able to get it right as we got it at 4.9 running at 1.5 v but the stability was shocking aswell as the temperatures this time round.


has anyone got an asus p8z68-v and overclocked to a decent speed and would someone be able to help me to achieve this potential that i am after as i am new to overclocking and want to learn more, maybe even some step by step pics if it would help and not be too much trouble.


thanks in advance

I'm sorry to say, but if you can't get a stable OC to 4.9GHz at 1.475v, I really doubt it's going to happen with any voltage at all. I can have my 2500k at 5GHz with only 1.376v. Not all chips are equal... But TBH, anything above 4.2 isn't essential for day to day use and gaming, unless you are running some kind of really CPU intensive program.

EDIT: You should be able to OC to 4.9 just by changing your multiplier and setting your volts to whatever it is that chip needs, you shouldn't have to change anything else as sandy bride chips are designed to OC with all of their power saving features turned on, that's what turbo boost is.
I'm not sure how helpful this is, but try this: http://www.overclock.net/intel-cpus/...00k-lamas.html

This, kind of.

You shouldn't change BUS/ FSB for turbo, only multiplier. If your board allows to, up the multiplier's voltage (CPU VDDA on AMD boards).
