CPU Overclocking

[T99]

Hello community!

 

I recently built my PC and I have an i5 6600k equipped, and a Corsair H100i v2, Now, I overclocked it to 4.6GHz, using Auto Vcore from Mobo, and it never went above 1.23V.

 

However. There is one thing that is concerning me.

 

My CPU (AIDA64) Stress Test temps are way lower than i expected.. 39 degrees max.

 

Is this normal?

if its legit then you won the silicon lottery.

Go do some benchmarks, as long as the results are close enough to others there should be no problems. Also, Skylake generates less heat and you're using a liquid cooler

You can go to 1.35V I think without chip degredation over time. Set it to that and see how high the clocks can go @T99. I think you won the silicon lottery though

Isn't there a thing with skylake that the 6600k won't boot with a clock higher than 4.9GHz?

Never heard of that.

Can you post some HWMonitor screen shots during load please? Keep the mobo and CPU tabs open (you can colapse all the others).

Sure.

I just tried 4.9GHz at 1.44Vcore, it did post, but shortly after I entered windows a BSOD came.

all that proves is that you did not win the silicon lottery.

I Just got the system stable at 4.95GHz! It was set to 1.43Vcore. However 4.7 Posted and is stable at 1.37V.

wtf.

You lucky bastard.

[YubinTheBunny]

Are you sure it's stable? How long did you run the test for? 10mins? I only consider something to be stable if it doesn't bluescreen in a 24hr stresstest

Yes. I did run the test for 10 minutes and then attempted some more overclocking. But I just can't get past the 5.0 GHz barrier. I have now been running it for over an Hour and the temps never went above 60 degrees Celsius.

 

Do we have an idea why CPU-Z Validation keeps saying Unchecked? Everytime I validate it it is always "Unchecked".

[T99]

I know now. i can't run it in extreme OC mode.

 

Here is a CPU-Z Validation Link.

 

http://valid.x86.fr/g0exzh

[T99]

Well. For anyone that wants the AIDA 64 CPUID's screenshot there you go.

 

[T99]

Yes! I just got it over 5.0GHz! It's running 1.452 Vcore!

 

CPU-Z Validation:

valid.x86.fr/2kv7xr

 

(Still yet to test for stability, has test running in background for over 7 minutes now. Will update when it goes past 2 hours.)

 

EDIT: The highest temperature as of currently is 64 Degrees Celcius.

[T99]

The 5GHz just passed 2 hours of AIDA 64.

 

Highest Temp was 69 Degrees. but it is sitting arounf 65 66 degrees.

I bet this will crash in your next gaming session... AIDA isn't very stressful.

I wasn't planning to game on that anyways, dialed back down to 4.8GHz at 1.34Vcore.

 

I was just going to be how far it could push, and that really impressed me.

66C at almost 5GHz is very good result, i guess you cant be happier :-)

Allright. Then fire Prime95 and watch your computer actully get on fire (with the previous voltage, 1.34 isn't bad).

I ran prime95 for 24 hours (1.34V 4.8GHz) straight and turns out the temps are just over 50 degrees.

 

P.S. Turns out the CPU only utilized 1.308Vcore when I gave it 1.34V. That's a win win.

 

I ran GTA V and CS:GO (yes great benchmarking game) and they worked perfectly fine. I was able to play cs:go for over 6 hours straight without anything failing (Although my parents called me to dinner) and the GPU was cooperative as well. (GTX 980, If you are wondering)

What the... latest version on small FTT at 50C? What the hell do you have for cooling and ambient temps???
