Overclock going bad/Motherboard Help

[Raider102002]

So about a week ago while playing FarCry 3 game would just close without a crash error, it would do this every 15-60min lowered my gpu clocks and still would crash so couldn't figure why it was crashing. So i played another game to see if it was game played AC2 and would also do it while playing that game. So then looked into the event view and saw i was getting a lot of warning called WHEA-Logger Event ID 19 and saw it was a cpu error so ran at stock was @ 4.2ghz @1.2v.

 

Finished the game AC2 with no more errors and crashes so tried OC today on auto voltage to see if it was a voltage problem didn't like what voltage auto was getting but 1.29v was testing to see if voltage issue. When i tested a bit, very little was just watching YouTube and downloading a game saw WHEA-Logger was getting warnings, went back to stock and warning stop. 

 

Then i decided maybe its the LLC so ran at auto voltage OC 4.4ghz high LLC atm and no warnings but i don't like the voltage 1.315v really high for 4.4ghz in my opinion getting 60c peaks with just minimal load on cpu.

 

So my question was my mobo or cpu going bad? or was it just that i had to set LLC higher ?

 

on side note old OC 4.2ghz 1.2v LLC regular 12hr Prime test pass can't remember if did a 24hr

 

Will be doing test to see what works

What CPU and motherboard are we talking about here?

 

Also FC3 crashes for me all the time too. Think that's just the game.

Just did a 4.2ghz LLC High 1.2v before i could even begin to test got warning

Nothing is going bad, if you get that error in the event viewer it means that your overclock is unstable. Now the error may only occur in games and not when you test it with prime. 

You just need to tweak around with voltage and LLC-settings to find out when your CPU starts being completely stable @4.2GHz. 

Also, disable Intel SpeedStep in your bios. It should be stable at around 1.2-1.3V though.

Okay thanks everyone for the fast response posting on phone running a prime 95 test 1.21v so far no errors while just starting PC will get back with results

Just wanted to give an update seems i found a good voltage 1.24v for 4.2ghz 

I did a 6hr Prime test i know its not 12/24hr one but didn't have time this week for it but the 6hr one i did pass with no error @ 1.21v but as soon as i did video it gave me warnings.

 

So i decided to bump to 1.215,1.220,1.23 and each time i went longer without getting the warning of  WHEA-Logger

 

​At the moment been gaming/ watching videos and no warnings for 6hrs longest i have gone for so seems stable or i am getting close to the right voltage for my OC 

 

Just again wanted to thank everyone for the help
