i7 3770K Overclocking Experiences

[areuz]

Hey there,

I've recently upgraded my rig into a better, huge case, and did a custom watercooling loop for the CPU (GPU after a upgrade, not enough cash atm.).

After overclocking the 3770K to 4.4GHz at 1.24Volts /It's still kinda unstable... but I will work on it later/ I've noticed that the temperatures with this kind of cooling loop are really high.

There are some details though, the CPU temperature is not as high when I use Aida64 than when I use either IntelBurnTest or LinX. I will attach all of the stress test applications along with all the information needed.

 

Aida64: Temperatures were in range of 70C° ± 4C° and peaked at 77C°/ The TDP was in range of 80Watts / Voltage was pretty stable at 1.234 - 1.24Volts <- All of this according to HW Monitor and Aida64's CPUID monitor.

IntelBurnTest: This was the weird part, after it allocated all the RAM that It needed, It went from stable 65-70C and 78Watts to whapping 80C°± 4C° along with a 99Watt TDP! / Voltage was still in the same range as in the Aida64 test.

Linx: Pretty similiar story to IntelBurnTest, but 1-3C° lower temps, a little lower TDP, more PC lag, and some PC Freezing and me having to force shut it off... Pretty unstable application in my opinion, not the first time this has happened... I don't even have a screenshot of this one, but I remember what the results were when I ran it a week ago, after playing some more with the OC.

 

Rig:

CPU - 3770K @ 4.4GHz & 1.24Volts

RAM - 16GB Corsair Vengeance @ 1800MHz

Cooling loop: XSPC EX420 Rad - 35mm thick, FPI 19; 13/19mm or 1/2ID 3/4OD tubing  ; D5 Pump ; XSPC RayStorm Waterblock ; 3x NF-A14 FLX fans <<With this loop I think I should get lower temps.

If you have a 3770K and it's overclocked I would love to see your overclock as well as the temperatures, wattage, cooler, and everything else. All of that can help

Thanks in advance,

I seem to be missing the screenshot where you could see the voltage...
Instead here you can see my GPU and its overclock too

Thanks for the quick answer

Could you please tell me what cooler you are using and run a stress test and use something like that ThermalRadar or HWMonitor to show the load temps?

Also, 1.135V is really low for a i7 3770K @ 4.4GHz, you must've gotten a CPU right from the middle of the wafer

I'm using an H100i, and yeah I got pretty lucky with the voltage

Load temps used to be 63C max, but after I remounted my H100i this year for some reason they now go up to 67C even though I properly cleaned the thermal paste and replaced it with MX4.

It might just be my H100i needing to be replaced or remounted...I will be changing my case within the next month so I will take that chance to remount it again.

 

Actually now that I think of it...it might be because it was really warm this summer...I will see how the temps are this winter

So.. You with your insane voltage luck probably can't help me

I would need a similiar voltage and frequency, and the results with that setup... Unless you want to set your CPU to 1.25Volts ofcourse

Sooo.. Waiting for somebody else's specs.

1.25V is alright.

[areuz]

1.25V is alright.'m 

Yeah, it's still in the acceptable range.. But the problem is, that it goes up to 80C° with my triple 140mm cooling loop. I'm asking If that is even close to what It should be.

You could try remounting the CPU block, changing paste, fan swapping. 

 

When i ran my 3570K at 4.7GHz 1.36V Intel Burn Test was only at about 80-90C. And that is with the H80i. 

 

Not too sure what else you can do.

its probably the thermal interface material on the cpu die. i run mine at 4.625ghz on 1.36v on air cooling and it stays under 75c. it has been dellided using cool laboratory liquid pro

Yeah.. that's what I'm probably gonna do. But the fans are totally new and the paste was applied 2 weeks ago (I used MX-5)..

I never realized that it was the CPU's fault. I also had a H80i, I ran at around 4.2GHz (I don't remember the voltage) and It was allways like 80-90C°... It was strange, but I though that It's the H80i's fault...

 

But hearing all of your guys' responses, I now know that it is the CPU's fault. I will try to get a replacement unit, and update this thread after.
