Is my CPU Overclocked ?

[Ray_]

i am not expert when it comes to turbo boost and OC
what i know is .

overclocking will set all cores to a specific speed , " we need to increase the voltage "
whether it was a single threaded workflow or multicore workflow
the speed of all cores will be the same . 4200 mhz for example .

and what i know about turbo boost is
1 core = 4.5
2 cores = 4.4
3 cores = 4.4
4 cores = 4.2
8 cores = 4.0
the turbo boost will work to the maximum limit while single threaded is needed
the turbo boost will decrease the speed as the used cores are increased

but this is not what i am seeing here . for example when rendering in cinebench
all cores are running at 3500 mhz , except core number 9 , its 4000mhz
i went to the bios and it was set to " by specific core "
i changed it to " sync all cores " without changing anything else

i ran the cinebench and the results were
all cores are running at 4000 mhz , but i didn't set any multiplier to 40 !
everything was set to auto and i didn't increase any voltage
all what i did since i bought the system is enabling the xmp profile for the ram
and multicore enhancement option was on by default

so my questions is .
is sync all cores considered as overclocking ?
even though i didn't increase the voltage
and i didn't add 40 multiplier , i left everything to auto .

should i be using by specific core or sync all cores ?

i saw someone on youtube doing a test on the same cpu
he was getting the speed about 2999 mhz .
but mine is 3500 mhz and core 9 4000 mhz out of the box
and when i change it to sync all cores , all of them are running now at 4000mhz
is my motherboard overclocking the cpu automatically ?

what is the normal speed i should be getting from this CPU without any OC ?
3000 mhz ? 3500mhz ? 4000mhz ? , on all cores while rendering .

My CPU is Core i7 6950x
Processor Base Frequency 3.0
Max Turbo Frequency 3.5
Intel® Turbo Boost Max Technology 3.0 Frequency 4.0

It's normal, 4GHz is the turbo frequency of your CPU, and regarding the BIOS settings , 'Sync all cores' is the better option IMO.

thanks taylor , so i am not overclocking anything here ?

Nope, everything stock

Thanks a lot , i appreciate your help
what got me worried is the cinebench results
by specific core i got : 1895 cb
sync all cores i got  : 2112 cb
so i was worried that the cpu is overclocked . thanks again
have a nice day .

Nope. What motherboard are you using?

Wait, you were worried that your CPU is overclocked? You bought a 6950x and you don't plan on overclocking it?

As i told taylor

lol , at least for now , maybe later down the road , i have a water cooling by the way
but i heard OC shorten the life of the cpu even if the temps are great .

No, it doesn't. At least not by any appreciable amount.

 

EDIT: At least assuming that you don't push core voltage over about 1.3 to 1.35 volts.

when all cores set to 4000 mhz , the max voltage is 1.217v " sync all cores AUTO "
when all cores set to 3900 mhz , the max voltage is 1.190v " sync all cores 39* "
when all cores set to 3500 mhz , and core #9 to 4000 mhz ,  the max voltage is 1.084v " this was the default setting * " by specific core "
which one is the best for 24/7 usage ? if i want the cpu to last +8 years .

Out of the box it was " by specific core "
where all cores runs at 3500mhz and core number #9 runs at 4000mhz
should i put it back that way ?
because i don't want to OC , It will shorten the life of the CPU

That's your chip and motherboard. I would pretty much do what he does and set the AVX offset number to 3 instead of auto.

 

For 24/7 use meant to last nearly a decade I would stay around 1.275 max on the core voltage. Once you set the voltage that you want, just start pushing up the clock until you find the highest that it is stable at with your temperatures remaining at or below about 70-72 c (on each core individually).

 

That should get you a nice, modest, 4.3 to 4.5 Ghz stable clock without any noticeable decrease in life span.

 

Yeah, you can do better and go further but that will be a nice, modest, OC that at least gets a decent bit of extra performance out of your chip.

 

EDIT: Only a quarter of the chips (roughly) can hit 4.4+ on water at 1.35 volts or less so if you are only hitting 4.2 to 4.3 GHz at 1.2X then don't be disappointed.

thank you so much i appreciate all your efforts
i watched the tutorial , it's pretty good , i will try it .
have a nice day .
