i7 4770K Safe Temps?

[xD6N]

hey guys i have just lightly overclocked my cpu, i have just ran prime95 for 10 minutes and have noticed that all of the core temps are around 50-55 degrees celsiues. it may sound a bit stupid but i am new to OCing so any responses would be great.

 

(H100i Watercooler)

(4.2Ghz OC)

 

Core voltage 1.279

[Prokart2000]

yes fine max i would go is 85c

[jameshumphries47]

i would feel save at arround 80*C 

[flibberdipper]

I would try to make it run cooler at 80C, and then at 85C I would really try to make it run cooler.

 

And you should NEVER use Prime95 on Haswell, since it makes the CPU's voltage go through the roof.

[Enderman]

You need to test at least an hour to get to the max temps

Also use IETU instead. It is better for your CPU

oh shit ok thanks for that information. im going to load up bf4 and play for half an hour and check the temps afterwards

Sounds like a good plan. If you want to stress it out, use Intel Burn Test.

[DudeWazap]

80°C would be the highest I would run mine at.

i took theese results from speed fan whilst i was playing

 

all of the cores averaged around 40 degrees celsiuess the highest anyone of them went was 44 degrees celsiuess. does speed fan have accurate results? and should i now overclock further?  core voltage remained at 1.2V which was what it was before I overlcoked.

On Intel it usually does. Take the voltage to 1.3v or so (no higher than 1.35v, preferably), and then see how high you can push the clock.

use realtemp to monitor temps, also go higher if you need too. Could get a solid 4.5GHz at 1.30v. keep temps under 85c.

Have fun OC'ing

You really shouldn't use games as a stress tester, if you don't want to use prime95, go google "cpu stress test", and download another program, the point of a stress test is to bring your cpu to its absolute limits beyond what would happen normally to see if it still can be stable. Games are normal use which means it won't actually "stress" the cpu.

 

Here are my own ways of OC'ing, may not be the best but its how I do things.

1. Go into bios and jump my cpu frequency up in 50-100Mhz jumps,

2. boot up into windows and run the stress test for ~5-10min

3. monitor the temperatures near the end (anywhere below 80 is perfectly fine 85 is acceptable)

4. if it doesn't crash/produce errors repeat until it does produce errors

5. Either up the voltage (most people go 1.3V-1.4V based on cooling) or reduce the frequency by 10-20 Mhz jumps

6. Rerun the stress test to see if I'm still getting errors

 

if you are uping the voltage, up it in small increments like 0.05-0.1V the 1.3V-1.4V is usually the ending result of voltage changes for overclocking

 

Once you reach a point where you can go "ya I want to run this for my everyday use" run the stress test overnight, if its still fine in the morning, congratulations you now have a stable OC'd cpu, if not keep fiddling with voltages and frequencies until you do.

 

Just note both higher frequency and higher voltage =  higher temperature

higher frequency =  more unstable

higher voltage = more stable

 

you must balance these three things to get a stable overclock you can be happy with

Thanks!

No problem.

ok thank you, i have just bumped up my OC to 4.4Ghz its currently on 1.249V on Idle. And the cores are all on 20 degreese celsues on IDLE is this acceptable?

[DeuS_CaNoN]

Overclocking is ALWAYS luck of the draw, 4.4Ghz seems like a modest-average overclock but you must ALWAYS run your stress tests to see if the overclock is stable

 

Run your stress test for 5-10min, if it crashes I'm going to guess you don't have enough voltage going into your cpu, up that to maybe 1.3V I see you have a H100i cooler so I wouldn't worry about temperatures unless you see 85 degrees on the stress test

ok i just stressed my cpu by rendering a 7 minute video max temp that i saw was 59 degrees celsiuess, this is ok isnt it?

[DeuS_CaNoN]

I still wouldn't use video rendering as a stress test, its not utilizing all the cpu, this might go over some people's heads but a cpu has multiple parts to it, L1/2/3 cache, Floating point calculators and an arithmetic calculators. Stress test programs tests ALL these parts to their maximums (your video rendering might only be testing the floating point parts to their maximums which why cpu usage will still say 100%). 

 

I suggest either continue running prime95 OR go google "cpu stress test" and download another cpu stress test program

No higher than 75C.
