help needed core i5 4670k problem

[REVENGED]

hi guys i need help
5sep i bought combo of asrock z87 extreme 6 and 4670k
it was running perfectly for 20 days on 4 ghz with 1.050v stability 100% tested (prime 95) (intel burn test) all passed without issue
now problem is that my pc restart randomly with blue screen error (whea uncorrectable) about 10 time till now specially when cpu is under heavy load now its happening even at stock setting everything at auto
so i think main issue is processor to confirm this i borrow friend i7 4770k and overclocked it 4 ghz his chip required (1.030) and its was stable
to me its looks like processor is faulty

i am using all of my other components from my previous build
ram gskill 4gb
psu antec tp750watt
gpu 760 evga 2gb
hard drive 500gb

so what you guys think my cpu is culprit (according to me it is)
my processor is still in 2 year 11 month warranty

ya i am lucky one these kind of thing always happen to me
there is also strange noise come from motherboard when i stress cpu using my 4670k
but no sound using friend 4770k

currently using Freezer 7 Pro Rev. 2.0
max temp are 70c max at 4 ghz using intel burn test
while 62 max using prime95

cpu is not even stable at 4 ghz at 1.150v while previously it was stable at at that clock using 1.050v

Revert to stock speeds.
Load setup defaults in bios and if soo then Update ur bios..
That will sure....help..
And stress test ur system on stock speeds and see if u get the same prob.
and then report back..!!!!

ya mate i already mention above everything at default setting when i stress cpu takes 1.2v on auto and still not stable after 40 to 50 min of prime it will crash (forget intel burn test)
btw i am running latest bios which are 7/03/2013

Bro then it can be ur Ram and PSU as well.
Check it with MEmtest...and try to change psu as well..!!!

4ghz on 1.050v dammmm

sir i dont think so i was running same ram and psu with my i5 750
didnt encounter any random reboots or any error for 4 years so i cant blame them


btw memtest pass without any issue for 2 hours

4ghz on 1.050v dammmm

at 4.4 it required 1.205v but problem lot of heat shitty cpu cooler 85c

 

[mave3]

Bro also check the CPu on another system..
that will also give u a good idea if the cpu is faulty or not..!!!

It is definitely your processor. However, before you go into warranty hassle, check it at your friends system. And all testing should be done one default settings.

ok guys today i did lot of testing
this is how it have gone so for
1:
by replacing friend 4770k in my mobo it stress ok for 1.5 hour then it crashed his 4770k was also not stable at 4 ghz 1.030v giving same error then next thing i did is replace my 4670k and place in his mobo(asus) overclock at 4.0 with 1.050v and stress it ran without any issue for 2.5/h no crash at all
2:
next thing i did is replace his 4770k with my 4670k in asrock z87 mobo and then i stress it with same clock/volt and it ran without any issue for 2.5/h

so conclusion is that mobo itself is the issue i think sometime it is not providing constant voltage to cpu which result in blue screen and the crash with same error (whea uncorrectable)
currently now its running ok with 4670k at 4ghz/1.050v
for 2 to 3 days i will check its stability if it crash again i will send mobo for replacement

so guys what you think is it possible that sometime mobo is providing voltage to cpu and sometime it doesn't

ok guys its started giving blue screen again
i am reclaiming warranty on mobo how long this process will it take

You MB Power Phase gave Up Simply On Stresss......!!

Now They Are Not Even Stable At Normal......

Reclaim And It Will Take At-least 15+ Days (I Guess)
