4930k dying? :/

[mechanicalfluff]

Seems like my 4930k is dying; but could it be the motherboard?

 

My original 4.7ghz overclock failed at 1.37v and it started to bsod. I have a large custom loop, temps are never above 62c no matter what i do, even with the 1080 in the loop.

 

Now, when I revert to "optimized defaults" it still gives me a bsod. I need to use 1.4v to make it stable at stock 3.5ghz - but that voltage is also stable at 4.2ghz. 

(^1.39v at stock clock = bsod. 1.4 is stable at stock 3.5 and 4.2 -- 4.3 fails)

 

Ran memtest on the ram on this board as well as my z77 mpower board, all is good.

 

Could totally use some experienced folks' advice

Hardware doesn't degrade, it won't use more voltages over time, if a overclock is stable day 1, it will stay stable until it dies. Have you tried updating the BIOS to the newest version?

i would say motherboard VRMs have gone bad

yeah, it's currently on the latest. I've even tried older (previously stable) versions in months past.

What would point you to that?

If i put all of the power delivery options at "extreme", it still bsod's. Is that a good indicator?

 

I've never had an overclock fail like this before.

Every other build i've done is still stable to this day

i would guess one or more fases has gone bad and arent provinding you enough amps to properly use the PC unless you crank the voltage, CPUs dont tend to fail in this way AFAIK and they just produce a critical boot error when booting if they die

i see!

 

So basically i'm compensating for the lack of power by applying voltage. By applying the voltage i'm giving it just enough to remain stable; picking up the "slack" from a bad phase

yah thats what im guessing so a new motherboard is what you need probably

Good catch  thanks

 

Heck, i'll even save it and grab a cheapo xeon on ebay and use it as a nas/transcoding box

now... to find an x79 motherboard... 

 

one that doesn't cost 1000 bucks

Overclocking does degrade the processor's reliability over time faster than if it ran at normal. However "normal" means whatever the manufacturer tested with. If you overvolted the part, then the degradation is faster. Think about it this way, if you ran a water pipe rated for 50 PSI and you inject a 60 PSI stream into it, you think it'll last as long as if you injected it with a 50 PSI stream?

 

So what I'm saying is, if you get a known working motherboard, don't be surprised that you can't overclock your processor to what you had it at before.

Used mobos of sockets that are out of favor cost so much.   Mobos are like the most expensive used part to get since they usually die the most often and as a result the working ones fetch a decent price.
