Help With 2500k OC

[pcexplosion]

I am trying to overclock my i5 2500k to 4.6 but i everytime i use prime 95 i always get a blue screen like 1 minute of running it,im trying to find out why its doing it.I dont think it over heats because on core temp its in the 40's.

mobo:MSI z77-gd55

ram:GSkill Ripjaws 1333

psu:Corsair TX750

Mobo settings:

cpu ratio-4.6

vcore-1.355

internal pll voltage disabled

intel turbo boost disabled

enhanced turbo disabled

spred spectrum disabled

EIST enabled

C1E support disabled

intel C state enable

overspeed protection enabled

Maybe your Vcore is too low. Is that the Vcore under load or the VID?

Check that your RAM is properly configured

First, i woukd like to say that i am not an expert when it comes to overclocking.

The blue screen could mean that the application crashed because you have an unstable overclock. You may be able to test it at different voltages and see if that helps. Your overclock might be different than someone else's because each CPU is different. If this doesn't work you may have to turn down the frequency.

I hope that this helps :)

How should i configure my ram beacause I dont think it can be ocerclocked and If I use the oc genie button it goes to 4.2 on 1.350,so should I rise the vcore

I would say so

Just research and find a good voltage to make sure that it will not damage your CPU and ruin its lifespan

how much vcore should i go up because i don't want to burn my chip

After some research I see others saying 1.35V, however I have seen others say to set the voltage at auto on msi boards. I would try it on auto.

[pcexplosion]

was that on z77 boards?

I think on z68. I am probably not the best person to ask about overclocking. If you search for i5 2500k overclock like I did, you may be able to find some voltages that will be safe to use when overclocking to 4.6

what are the temps for you cpu? idle temps and the temp for right when you turn on prime 95.

[pcexplosion]

with prime 95 load it was in the 40s

[pcexplosion]

is there anything i should enable/disable in the bios?

[AJRicho]

firstly disable EIST

disable intel c state

enable the pll voltage to around 1 volt

then try from there

I Changed it to 4.5ghz and now it doesnt blue screen

the max it hits is 70 c

[pcexplosion]

well it blue screen after an hour,would it need more power,I put 1.350 vcore

[pcexplosion]

its not stable on 4.4 or 4.5

[pcexplosion]

its not stable on 4.4 or 4.5

but it hasnt crashed yet on 4.3 with vcore 1.300 but on cpuz it says its only using 1.280.

What does Overspeed Protection do? We want overspeed :P

I'd disable it and try to Prime again.

MY 2500k can go up to 4.7 on 1.5v on my Z77-UD3H

[Wats]

its not stable on 4.4 or 4.5

Vdroop. You need more LLC.

[pcexplosion]

i disabled it it still bsods on 4.4ghz

[pcexplosion]

i dsabled and it still bsod

[pcexplosion]

MY 2500k can go up to 4.7 on 1.5v on my Z77-UD3H

of course you can get that high with that voltage but i dont want to fry my chip
