HELP i5-2500k irregular vcore cause overheat

post #1 of 10
Thread Starter 
Hi guys, tearing my hair out this last few week...my i5-2500k vcore reported in the bios is jumping from 1.3~1.5+ causing the cpu to overheat to 65c+ thus the pc had to reboot. My spec as follow:

i5 2500k with Hyper 212+
ECS H67H-i = all on auto setting. No vcore control whatsover
Cooler Master Silent Pro Gold 600W
4GB DDR3 1600mhz Winova Ram


Yea this is an itx MB since my plan was to build a gaming htpc using SG05 as the case. Since im stuck on this prob the build put on hold. I cant even install windows since its just reboot once start to boot from the CD...

The ram & psu came from my last pc so it should be working fine. Tried updating the MB bios also the same. Reseat countless times also the same. Tried the stock cooler still the same result...

The MB & i5-2500k bought new....maybe either of them defective?

Is everything in the BIOS currently set to the factory defaults?

try changing the voltages rather then setting them on auto u will roughly need 1.375 or 1.4 vcore voltage. setting the voltages on auto is a very harmful thing for the motherboard i would prefer u check the motherboards VRM i know the VRM issue are more in AMd but sometimes the intel mobo also face them
Hope that helped

Well the problem is i cant set whatsoever voltage to the cpu. It only come in a preset of +0.500mv,+0.750mv & so on. No option to decrease the value or set a certain value.

Disabling all the power saving options also still the same result..

i meant the stock voltages for 2500k are 1.3 i guess so give is a bump of +0.100mv

errr but the problem is bios reported my vcore 1.5v already & that caused major overheat while running on stock speed..

wont it kill the 2500k if i give it another bump? since its way over the safe limit...

Not sure why you bought a "k" series CPU with a H67 board unless you plan to upgrade the MOBO later.

As to you issue, Im not sure as to why it would be spiking your voltage like that, what PSU do you have?

I have a feeling it is either the MOBO or PSU that is defective.

Try +0.500 and then reboot right back into the BIOS and check the voltage. If it's lower, then we have succeeded. If it's higher, then I want to see the rest of the BIOS options.

Well the K was on sale that day same price for standard 2500 so just bought it maybe will pickup a zotax z68 itx in future if budget allow.

I have tested with my last build psu & a brand new Xigmatek NRP-MC802 800W psu so i can safely ruled out the psu. So thats leave me the MB & proc. Since nothing is connected beside mentioned above & a brand new 2.5 500gb wd hdd

Will test the setting later once reach home
