Specs:
OS: Windows 10 Home (64bit)

BIOS: v.1504

 

CPU: i7-6800k 3.4ghz.  OC: (4.4ghz -- 1.45v)

RAM: 16gb 3000mhz G.SKILL Trident Z RGB (set to 2133hz -- v1.36)
MOBO: ASUS x99 Strix Gaming

AIO: NZXT Kraken x62

GPU: MSI GTX 1080 Gaming X 8gb
PSU: Cooler Master 1200w 

Monitor: AOC 3840x2160

SSD: Samsung 950 Pro (256gb)

SSHD: Seagate 2tb 

Case: Phanteks p400 tempered glass 

 

At the time of the CPU spikes i was running cinebench r15, CPUID hw monitor and dual intelegent processors 5

Well.. Which cooler do you have? Critical info

1.45V is that a typo? that's way too high for that CPU.

What cooler are you using?

 

It's pretty common for core temps to vary by 15-20% across cores, as active threads are switched from core to core, but those temps are crazy high for a 6800k.

 

1.45V is also extremely high, and what is causing your temps. Did you set that manually or is it on auto voltage? Turn it down to 1.35V at the most and see how your temps fare.

no typo, running at 1.45 look at the image ^^

Well the reason you are running so hot is the safe max for that CPU is 1.4V You either need to lower that or be prepared to kill it sooner rather than later.

 

EDIT: I've not owned one but I've heard the 5820K overclocks better than the 6800k so if this is a recent purchase you could change and see better results.

I think his point is that it's way too high, dial it down by at least 0.1V.

NZXT x62

and it was auto tuned to 1.425v but last time i had it there it was flaky. kept getting IRQL_NOT_LESS_OR_EQUAL from windows a q-code BF from my mobo, which to my belief is low Vcore.

And yes, 1.45v is too high for that CPU. You might wanna go way lower than that.

I recommend lowering the voltage, maximum 1.4v

Auto overclocking is rarely stable in my experience. Do it from scratch.

Not necessarily, it's usually a RAM issue. It could also be OVP being triggered by those crazy voltages.

 

It's a crazy unnecessary voltage for that CPU, you should be able to get it to run stable at 4.4GHz with 1.37/1 .38 at the most with that mobo and cooler.

Not related to cooling just to grab your attention.

He should but if he lost out big time on the silicon lottery and requires those settings for that frequency then he needs to accept defeat and lower that voltage.

[MrJarhead]

if youre going to overclock please read up about it before doing so, this is how people break things. never allow cpu voltages to be automatically done, you should always manually set them.

I dropped it to 1.35v and the temps were 72-86
Proceded to run Cinebench and it crashed:

Clock_Watchdog_Timeout and then BF low vcore error occured.

Ill try 1.4 and see if that keeps it cool and stable

thanks again for the help on this one.

Crashing indicates an unstable overclock, theres more to it than adding voltage.

thanks ill take a look. ^-^

the Mobo Qcode was for the vcore voltage too low. ^^

Mobo codes aren't always accurate by any stretch, and each one can mean multiple things. What it specifically means is that the CPU isn't receiving enough stable voltage, not necessarily that VCORE is just set too low. That Qcode usually means the LLC is off, not that VCORE is too low.

Noted thankyou ^^ gonna bench again with core voltage at 1.375 and a 0.025 offset brb

lowsest max core temp 75`C (167`F) 

highest max core temp 92`C (197`F)

idle is average 40-45`C

That's still too high for my liking. Do some monitoring during real world usage. Otherwise consider a custom water loop.

yeah it is about 5deg above what i would consider max, ive just adjusted my AIO setting for higher performance. ill rebench if i dont see any temp improvements ill slowly adjust my offset and try to keep it stable ^^

I said real world because these synthetic tests are great for stability but not indicative of real life temps. Open the monitor software, use the computer as you normally would for a day, then before shutting down check your max.
