Overclock degraded over time?

[MsTrMind]

Hey all,

 

Its been a while since i've been on the forum. 

A while ago (easy 2 years ago) I bought my 4670k and Z87-a.

Stable overclock running since I bought it, 4.5Ghz @ 1.25v; I let it run and it was 72h Aida64 stable (I went on weekend, and let my pc run :-) )

Over time I slightly upgraded my pc. 

gtx780 classified (EVGA) stock speeds

8GB of extra ram (now 16GB - 1600Mhz)

 

Everything was running fine (I only played Dota + small games, nothing too crazy).

I recently moved, and bought a new monitor (3440x1440). 

 

As I'm here, my pc slightly became more and more unstable. First it was after 2-3h of Dota that I got random crashes to desktop. Until now, where I'm at the point that the pc gives me random BSOD (sometimes 1h, sometimes 3h, ...) or again crashes to desktop. 

 

Now I'm running back on stock speeds, just to test, PC just passed 24h of Aida64 with no problem. 

 

When I take a look at the eventlogger, I see that every minute I get a WHEA-Logger event 19 popping up. 

 

Did I break my cpu?  Known problem? 

 

Every driver is 100% up-to-date, nothing is overclocked anymore (XMP is also turned off)

 

EDIT: updated my system

Degradation due to prolonged overclocking/overvolting is a known thing. It's unavoidable, and every CPU/GPU will succumb to it eventually.

Yeah, I knew that, but already after 2 years?! And this fast?

More voltage on stock speed? Its on system defaults

Well thats the thing, I'm able to get 2 hours on 4.8Ghz @ 1.4v on Aida (didn't test longer), 10h on 4.5Ghz @ 1.25v on Aida (didnt test longer). 

Stock gets 24h with no problem, but I have the weird eventlog things happening...
