2500k OC Help Please!

post #1 of 20
Thread Starter 
Hello I'm having trouble OCing my 2500k to 4.0ghz. I used this guide as a reference:
http://www.overclock.net/intel-mothe...-oc-guide.html
My specs are:
MB MSI|P67A-G43 (B3) P67 LGA1155 R
i5 2500k
CM 212+
12gb 1333ghz ripjaws


Even at 1.3v and 35 adjusted cup ratio, i keep getting a fail (computer restarts and message appears saying overclock setting has failed)
thanks for any help

you may just have to push the voltage higher remember the max voltage for the 2500k is 1.375v. some chips just need more voltage than others.

I'm having to use between 1.344v and 1.356v to keep it stable at 4.8GHz.

Bump the voltage, or use offset mode with 0.010-0.025v as the offset.

Question to DSP1, I thought you could go higher than 1.375v with a 2500k? I see people running 1.4v for their 5GHz OC. Is the limit really 1.375v?

ok thanks i'll try it right now. how come in the guide he could set it to 1.3? is it b/c he has a better cooler?
i feel silly. i went back into bios settings and found that it was already set at 4.0...this is after i had set it back to defaults after failed oc settings. what is the temperature range i should be under during stress?

ummm..... no

i have had mine to 1.5 but i wouldnt reccomend that for everyday use. 1.45 should be safe for everyday use(depending on cooling) but you shouldnt have any issues OCing to 4.0

please fill in your system settings under your control panel as well. it will be easier for readers to check your specs without having to jump back to the first page

try these settings:
multi- 40
bclk- 100.0(make sure it is manual and not auto)
vcore- 1.3
pll- 1.7
vtt- 1.14
enable pll overvoltage
LLC(load line calibration) if on a number scale:5 if on a setting: high/extreme

the LLC accounts for vdroop. vdroop is the voltage drop under load.
use cpu-z to monitor your vcore when you start prime95. how fardoes it drop under load?

if you get a blue screen:
101 is vcore related- up vcore
124 can be vcore related but can also be pll or vtt- increase vtt(no more than 1.2) or pll(no more than 1.9)

post your results after trying these settings

Correct, that's what Intel published and do you think a) they'd publish a number that would kill their chips and b) they wouldn't build in a little fudge factor?

So much wrong information and fear about voltage on this, an overclocking site.

Thanks for clarifying max voltage. After a failed config I decided to run as default. After visiting the forum and going back to adjust settings, i found that the multiplayer was already set to 40.
Under load I get max temp 51. Idle is 32; is this suitable?
Thanks everyone for all your help!
