overclock @4.4 now need help

[Im_Infinity]

i just got a 4.4ghz overclock on my i7 4770k i did a small ftp test on prime and temp reached 92c on one of the cores now i know in a real scenario of just 100% usage it only hit around 60c is there any suggestions you can offer me

If I was to overclock, I would get the 4790k, which is basically a 4770k with a better heat spreader that has a different compound between it and the die itself. I'd blame it on the poor heat dissipation of the 4770k

when i built my computer i was on abit of a budget and didnt look at a 4790k but now i wish i did but with the new skylake there is no difference with my getting a 4790k now i might aswell be getting a skylake

ok i just ran a cinebench cpu test and passed with hottest core hitting 64c

Well then you're okay, the synthetic test that prime does is a much higher load than any real world scenario would put on the CPU, even higher than Adobe rendering

Which version of Prime95? Run version 26.4, not the latest version. I'm guessing you'll see much different results.

That is the way Prime95 (new versio) works. It loads the CPU with basically every instruction possible thrown at it. It will make the temps much higher than any real world scenario. Prime95 is no longer a real good stress test because of that though the older versions still work fine. Use IBT, OCCT or the like.

Not to worry.
You are fine.
The cpu will downclock or shut off if it reaches a dangerous temperature. That is about 100c.

Prime95 is not a good test, I like OCCT better since it more closely uses normal instructions.

The metric to monitor is Vcore. You do not want it to exceed 1.3v for long term use.
At that vcore, you will not have a big cooling problem.

When you reach the max oc for your chip, back off a notch.
Implement adaptive voltage and speedstep so that your multiplier and voltage will be reduced when the cpu has little to do.

i tried 4.5ghz at 1.25v got into loading windows then blue screen so i put it on 4.4 at 1.25 and got into windows and now im just on the benchmark stuff

edit: i did manage to get windows on the loading part at 4.6ghz with 1.25v but i was met with bluescreen so i guessed i have a below average chip

my version of prime is 28.7

That will give you a much higher temps. If you run 26.4 you will see a more realistic temperature scenario. I'd bet you see at least a 20 C drop.

do you have a link for prime 26.4

ok just tried occt test on small one lasted about 2 minutes before crashing really not sure what to do now

 

[weberdarren97]

Do it again and when it crashes again, turn it back on and go into BIOS. Look for the CPU temperature while in BIOS, if it's higher than 40 Celsius then you have a problem.

 

[Im_Infinity]

i went straight to bios after crash and it was showing 37c on the cpu

 

[Im_Infinity]

ok im running the division which tends to get my cpu between 90-100% load and seems all fine it was just the stress test with occt that made me crash

 

[weberdarren97]

I would see that as warm but not hot, so you should be okay.

 

[Im_Infinity]

ok max temp on division was 61 but average of 50-55

I think you're fine

 

[Im_Infinity]

so should i be fine to just leave it on manual 1.25v and 4.4 and just play

 

[weberdarren97]

Just leave it the way you already have it set and "you'll be set"

Get it? Bad joke, moving on...

 

[Im_Infinity]

well if i experience a crash or anything ill come back to here and post thanks all for the help

 

[weberdarren97]

No problem, it's what I do
