Question about CPU

[Tek-Buzz]

Hello, i've been trying to get a stable OC at around 4.2 ghz but failed,now i guess 4.0 is a good spot for i5 4690k for now, i set it to 4.0ghz with voltage to adaptive, is adaptive voltage bad?

I know it pushes extra voltage,max it pushed 1.279v at 4.0ghz, in aida 64, but temps are below 65c so should i still be worried?

Is this much of voltage gonna affect the CPUs lifespan?

I already had 1.211v by default in CPU-Z when all was at stock speeds tho'.

Now that i've set it to adaptive, it stay 1.211v at idle but at 100% usage it goes 1.279v but temps are below 70c so sgould i still be worried?


I just changed multiplier to 40.
Max CPU cache is at "AUTO"
CPU Input Voltage is also at "AUTO" which is 1.776 v

CPU Core Voltage is " ADAPTIVE"

Thanks for help!

Your cpu should be fine with that voltage and temps. What are your exact systems specs as I would expect that cpu to clock higher.

Specs: i5 4670k
ASUS Z97-A
Hyper 212X cooler
GTX 970

I expected the same, but with 1.3 v it can't get stable 4.4 , temperature is not an issue, i never saw it reaching 85c weather i set it to 1.275v or a little further about 1.3, i even put the voltage to adaptive, at 4.4, still it gave me BSOD, i don't think i'm gonna go over 4.0 for now, even after a couple of years, this CPU is still very good, at 4.0 it is above good as of today.

I'm worried about the thing that i set the voltage to adaptive, is it normal to run adaptive or i set to manual and try to decrease voltage.

But since temps are never going 75c i think i'm all good, or running high voltage shortens the CPU lifespawn even if temperature is good.

1.279v for only 4ghz? Something isn't right or you got a really bad chip.
If you are having so much trouble OC'ing i would switch to manual voltage for OC testing and go from there.
Start with 1.250v and see how far you can go from there.

My 4690k does 4.5ghz at 1.250v, but remember every chip is different.

It is in adaptive voltage, sure it's gonna go above to maintain stability, i can achieve stability by lowering the voltage a bit more,but why should i? i don't go 100% cpu usage in games, therefore cpu stays at 1.211 voltage exact same voltage when i had the CPU at 3.8 turbo.

I don't know why in CPU-Z even at stock clock the voltage was 1.211v.

BTW do let me know what temps you are getting shady, when stressing the CPU. 😉

100% Load for 10 minutes ( Aida 64)

CPU-Z

See that 1.211v Core Voltage? it goes 1.279v for a couple of seconds often then comes back to 1.211v , max it goes 1.279.

Here's my temps using AIDA64, i log everything with the stability test too.

Have you tried increasing LLC? This should help with voltage fluctuations, though it may also increase the voltage too.

Decent temperature, i think you have a very good CPU cooler

I didn't mess with anything else than core multiplier, Core Voltage ( set to adaptive) and vinput, just these 3 only.

 

[ShadyHamster]

I would set your cpu voltage to manual (also go back to stock volts and clocks) and increase LLC to ultra high or extreme and go from there.
Once you've found a stable OC you are comfortable with then you can re-enable adaptive voltage and adjust it to match the manual voltage.

As for my cooling, it's a custom waterloop, 1 360mm rad cooling both the cpu and gpu, powered by a D5 pump.

Well, my stock voltage was already at 1.211v with stock clocks, it stays 1.211v in 4.0ghz all the time, just when the CPU load goes 100% it goes to 1.279v but often, it doesn't stay at that for too long, it comes back to 1.211v then repeats after a while.
