Overclocking CPU, i5 3570 at 4.5ghz gets too hot !!!

Look at the posts by me below

Well you can't just overclock any cpu, some are locked.
What kind of cpu and gpu do you have?

i5 3750

GTX 670 sli

Asus p8z77-v LE PLUS

I'm finding that my mother board has an option for this

I followed this guy on youtube and did everything he did on his bios to reach 4.5ghz

I then ran this program called Prime 95 and had it stressing my cpus for about 5 minutes. I checked CUPID HWMonitor and these are the results that I got for the temps during this 5 to 6 minutes

Core 0 Value: 88c, Min 34c, High 89

Core 1 Value: 94c, Min 36c, High 101c

Core 2 Value: 91c, Min 30, High 96c

Core 3 Value: 84c , Min 32c, High 90c

Package Value: 94c, Min 36c, High 101c

So is that good to go or what ?

I followed this, please tell me what I have to fix lol I don't know what is going on I just followed what he did, and I know those temps are no good

@Hydrolex:

At that rate, your CPU will be dead tomorrow, come back when you buy an aftermarket cooler.

What's your CPU cooler?

Prime95 is just a stability test. 99,99% of the time your CPU will never reach these temperatures with daily aplications.

And 1 more thing. Where do you live? we are closing to summer and some countries are hotter than others. There are countries that atm have 10 degrees of celcius and they are others with 40...

If your room has a/c then don't answer my last question :P

edit: Last time I checked 3570 wasn't unlocked. Did you mean 3570K?

Yea 3750k

My cpu cooler is zalman, orange looking it was 50 bucks...

Voltage was 1.32 I changed it to 1.25

This one? CNPS9700 LED

YES !!!!

So after changing 1.32v to 1.255v, these are the results after 10minutes, I'm gonna post the max numbers

Core 0: 83

core 1: 88

core 2: 86

Core 3: 82

package: 90

EDIT: after 16 minutes, the numbers stayed the same... but as soon as I started playing with my web browser, the numbers jumped to high 90s

@Hydrolex: Why don't you back it down to around 4.2 GHZ. 4.2 is really fast to be honest. I was running 4.2 GHZ but I was running 2.4 GHZ RAM. I would suggest running faster RAM like atleast 3.0 GHZ and than see if your happy with the overall speeds.

Vcore is what making your CPU temp goes to the sky. Keep it lower and try to find the best o/c you can have :).

Remember that your CPU shouldn't be at 80-90 C for 24/7, But they are more acceptable numbers.

I wouldn't recommend pushing a overclock past 4.2GHz unless you have literally the best air cooling solution or a water cooling setup.

Those temps are not high when you consider the fact that that cooler is not that good.

Leave it at 4.2GHz there is no performance advantage to gain going past that especially for gaming... Hell in most cases there's no performance advantage going past stock speeds with a i5.

If the temp is to high you lower the voltage and maybe even the overclock. Personally running my 3570K at 4.5GHz, but I got a custom water loop to cool it.

I played ghosts multiplayer ,watch dogs and I got max 69 on one core, the rest were low 60s...How low can I go for the voltage ? at 1.25 temps def saw a decrease

69 is nice. You could try lowering your Vcore a little more in order to achieve somewhat better temps. Even if it goes from 4,5 to 4,4 or 4,3, you will not notice any serious performance hit apart from benchmarks...

His cooler is a great cooler by zalman made from pure copper. I have the same in a Q6600 and after 6 years its stil rock solid. It can make a Q6600 B3 stepping to reach +50% o/c...

thanks, played watch dogs and it was still the same numbers and watch dogs is a cpu whore lol

But you are right tho, Prime 95 is just meant to stress the hell out of the CPU, I don't do anything close to that other than playing video games, I don't think I will ever get close to 80 playing video games or doing regular daily things on my pc.

Vcore voltage is set at 1.255 for 4.5ghz, what do you recommend ? would 1.967 be safe ? I mean I went from 1.325 to 1.255 and saw a significant decrease in temps

Well I guess the 1.967 was a typo and you actually mean 1,1967. Vcore is the major factor for the temps.

Yes, max 1,2V should be OK for O/C. Dave from TechpowerUP (the guy that reviews motherboards) manage to reach 4,6Ghz at 1,2V.

But all the chips are not the same so try the 1,1967 or 1,2 Vcore and try to do the max o/c there. (4,5 or 4,4 should be fine)

I wasn't talking about build quality.

The 9700 was a great cooler 4-5 years ago but now in terms of performance i.e cooling ability its not good... Its average, in fact a 212 Evo can do better with a push and pull configuration.

Which is why I said in order to get CPU's such as a 2500K, 3570K and a 4670K past 4.2Ghz you need something like a Noctua d14 or a Be Quiet Dark Rock Pro 3 if you are going with air cooling.

Ideally you don't want your CPU pushing past 60c while you are playing a game since it will be at that temperature for extended ammounts of time.

Omgggg you are right, I.197 but I accidentaly set it to 1.967 and the computer shuts down, cant even turn it on :(((

Edit, fixed it taking the motherboard battery out

The reference to copper wasn't for build quility. Copper is better metal for cooling. The only downside is that its expensive too :P.

And also Ivybridge and Haswell are not so good as Sandybridge when it comes to o/c at air.

It is well known if you increase the Voltage the heat will also increase.

You could OC to 1.35V on 4.6Ghz easy if you own the proper cooling (Noctua/Corsair H cooling)

EDIT: make sure you own a good airflow case as well, CPU cooler couldn't do all the work alone.

Did you manage to fix it?

If not, try using Clear CMOS. Go to your manual at 2-15 to see the details.

Yes, thanks ! I took the mother board battery out...

But I found out something cool about my mother board. I tried when I tried to set t the voltage to anything under 1.230, and the number would show up as pink, different color than before, it used to show as red... So after I rebooted the computer, I would get that blue ERROR screen that said there is something wrong with my pcs software or hardware. As soon as I set it to 1.230, the number was red again and it booted properly, so I think the motherboard was telling me already that anything under 1.230 was no good, and the sign was that pink color.

Anyways, I'm gonna see what results I get from 1.230

The zalman cpu heatsink is very outdated by today's standards. I wouldn't be surprised if it's worse than a hyper 212+.

Get yourself something better from thermalright.

I went from a zalman cpu cooler the big model (9700 I think is the name) to a thermalright ultra 120 extreme several years ago and the difference was massive.

The difference between CM EVO and Zalman CNPS9700 LED are 3-4 C. Hyper 212+ is even closer. They are not so high to justify a change in the cooler.

Ok so 4.5ghz at 1.230 gives me, max numbers

Core0 71

Core 1 77

Core 2 72

Core 3 70

Package 76

Well thats a great o/c for only 1,230v!!!. Are these numbers from prime95?

Unless your talking about prebuilt PCs with locked bios,you can overclock pretty much any cpu.

Just have to do it like the old times,and increase the FSB instead of just increasing the multiplier with unlocked cpus

Yes, used Prime 95 and CPUID HWMonitor

Great! I think you have a nice o/c.

Temps on applications should barely go above 60 C.

Congratz on hitting such high o/c with Ivybridge CPU with only 1,23V! :)

Thanks man ! Time to oc the gtx 670s haha

Lol. That would be overkill xD

Don't forget you're doing here pretty much balls to the wall OC with a poor CPU cooler, you'd get better results using Noctua D14/D15 or Corsair H100i (unless you're fine with those temps)

And this is why you don't overclock based on youtube videos instead of doing some actual research

Ding Ding Ding Ding!

He got lucky with his chip. Mine needs 1.3 roughly for 4.5GHz. If he get a better cooler which lowers his temps... Maybe another 10C, then he can perhaps lower the voltage another notch.

Yea thanks, I honestly don't see a need to buy a cooler since the max temp for these chips is 105c... and you know I will have this CPU for maybe another year or two before changing.

That hydro H100 looks huge, and looks like a pain in the butt to install lol I don't know if there's enough room for me to install that!

Yeah you can do it that way. But I was just wondering what he had. You never know these days. I see all sorts of people buying K cpus with a locked mobo.

Glad he figured it out though. I need 1.26/1.27 for 4.5 =P

Get a corsair closed look cooler or downclock your CPU.

lol I wish you read all the posts before you made the comment, I'm all good now... the problem was voltage was too high

My computer shuts down after 10 minutes of being in sleep mode. ANY clues soldiers ?

I'm sorry but that's such a impractical way of testing thermal performance.

According to that chart the difference between a 212 Evo and D14 is 1.8c... Where in practical real life situations the difference is almost 15c between the two. So if the zalman is 3c hotter than a 212 evo according to that chart then you can just imagine the practical thermal difference would be anywhere between 10-20c.

By practical I mean on a cpu in a case with a GPU... Its the standard for testing any thermal performance, which is no surprise because that's the only logical way of testing.

Well no.

Your link goes to a CPU test with higher thermal TDP (Intel i7 950).

i7 950 from your test is not even close to i5 4670K. 130w TDP vs 84w TDP....

So yes the test is right, its just not for the 4670K. Thats why you are miscalculating and misunderstanding. Unless you don't know that CPU collers perform differently for each Thermal TDP and CPU architecture.

And yes case has an good impact on both GPUs and CPUs. But it doesn't make a cooler goes from 3c to 15c unless its passive.

And in the end as you can see he manage to o/c his i5 4670K to 4,5Ghz whle reaching only 70-77c to all cores at prime 95. And for Haswell o/c, we know that this is a great o/c with great temperature numbers.

Ivy Bridge, not Haswell @Coseniath, still great to reach 4.5 at 1.23 voltage though. Personally I need 1.3

What do you mean by Ivybridge, not Haswell?

3570K, not 4670K. 3xxx series are IvyBridge, 4XXX are Haswell (not including the 2011 socket CPUs here)

I know which CPUs are Ivybridge, which is Haswell, which is Sandybrige, which is Westmere, which is Nehalem and so on lol...

I was actually asking what Ivibridge has to do with the situation here, in which part of the thing I wrote you are refering to.

Well this doesn't apply to 115x socket CPUs either. Pentium and Celerons are named 3xxx for Haswell and 2xxx for Ivybridge.

ps: Since you are a mod, do you have any clue why I cannot edit my posts? (I can press edit but editing tools don't appear).

ps2: I just did it but I couldn't edit the previous post. I guess its a firefox issue...

Absolutely no clue.

No idea on that. I know if I put my computer in sleep mode, wake it up and change the settings to turn the display off, after not using the computer for awhile. It doesn't work. It won't work until I restart the computer.
