Is this safe? i5-3570k @ 4.2 GHz 85 Degrees 1.200V

[oiCorrupt]

Hey guys so I was messing around and final found a solid overclock at 4.2GHz with
+0.005 after messing with it I went down to -0.005 voltage and now I'm getting about the same temps but my voltage is at 1.200 80% of the time is this safe how high can that get? and will it change when I have more programs installed etc?

This was after 30 mins of stress testing?

 

[oiCorrupt]

You should test it for about 2-3 hours and of course if you have better cooling system then you can go ahead.

Ok so if I run the stress test for 2-3 hours and it doesn't crash I will be golden or what am I looking for and is the voltage ok or too high?

Being at 85 C at only 1.2 volts seems really high. Is this 85 Degrees Fahrenheit or Celsius?

Never mind it looks like Celsius from the picture. I would look into your cooler or thermal grease because those temps seem kinda high to me. At 1.2 volts you should be getting low 70s or high 60s but being that this is an Ivy Bridge CPU you might have one of those poorly lidded CPUs that get really hot.

Being at 85 C at only 1.2 volts seems really high. Is this 85 Degrees Fahrenheit or Celsius?

Yes is says Celsius C and has the Fahrenheit next to it. High as in what temperature or voltage? and it was running at 90-91 Degrees Celsius half the time.

 

[ScienceMathsLover]

How do you reach to this frequency and voltage? Do you pick it manually?

The temperature. Your voltage is awesome for that clock speed. You might just need a bigger cooler.

Really? that temperature seems to be fine according the the Asrock mobo overclock guide not to mention its ivy bridge whihc runs very hot and maxing out is it 105 degrees

 

[oiCorrupt]

How do you reach to this frequency and voltage? Do you pick it manually?

Yes as I stated I put the voltage in fixed mode to -0.005

The 105 is your TJMax which is the point that your CPU begins to throttle to prevent damage. You want to keep your temps well under this to increase the life expectancy of your CPU. You can run at those high temps if you like and if you don't usually do any thing CPU intensive then you probably be fine.

My point though is that voltage correlates to temperature and that at 85 C I would expect this if you were north of 1.35 V but not for 1.2 V. This is a sign that your cooler is not very efficient or that you have too much thermal grease. But, Ivy Bridges are known for the temperature issues so this could just be par for the course. If it was me I would not like those temps and see what I could do to lower them.

For example I have my system clocked at 4.2 GHz at 1.48V (Yes I know but it is an i7 980x which needs lot of volts) and my temps are at 77c Max and 73 Average under Prime 95.

oiCorrupt,

Your screenshot shows that you're running Prime95 version 27.9.

Do NOT run any versions of Prime95 later than 26.6. Here's why:

Core i 2nd, 3rd and 4th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95 run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces unrealistically high temperatures. The FPU test in the software utility AIDA64 shows the same results.

Prime95 v26.6 produces temperatures on 3rd and 4th Generation processors more consistent with 2nd Generation, which also have AVX instructions, but do not suffer from thermal extremes due to having a soldered Integrated Heat Spreader and a 35% larger Die.

Please download Prime95 version 26.6 - http://windows-downloads-center.blogspot.com/2011/04/prime95-266.html

Run only Small FFT’s for 10 minutes.

Your Core temperatures will test lower with v26.6.

Core temperature is 5C higher than CPU temperature due to sensor location. Intel's Thermal Specification is "Tcase", which is CPU temperature, not Core Temperature. Tcase for your i5 3570K is 67C. Tcase + 5 makes the corresponding Core temperature 72C.

The relationship between Core temperature and CPU temperature is not in the Thermal Specifications; it's only found in a few engineering documents.

The relationships between Ambient temperature, CPU temperatures, Core temperatures and Throttle temperatures are shown below for your processor. All values are based on Intel documentation.

3rd Generation 22 Nanometer: 3570K (TDP 77W / Idle 4W)

Standard Ambient = 22C
Tcase (CPU temp) = 67C
CPU / Core offset + 5C
Tjunction (Core temp) = 72C
Tj Max (Throttle temp) = 105C

Standard Ambient temperature is 22C, which is normal room temperature, and is the reference value for Intel’s Thermal Specifications. Knowing your Ambient temperature is important because Ambient directly affects all computer temperatures.

What is your ambient temperature?

Your method for overclocking is wrong. If you pick frequency and voltage manually, the oc will be unstable and will produce more heat. Clear your CMOS to restore to factory settings and just refer this page:
http://www.overclock.net/t/91/ultimate-overclocking-guide
If you do overclocking appropriate method, you can go far away with less temps.

Do as I tell in that threads link

ScienceMathsLover,

Respectfully, your advice is misleading and inaccurate. The link you posted to Overclockers.net is to a Guide which does not apply to the i5 3570K.

The thread for that Guide was started in 2004. The last post ended in 2010. The i5 3570K was launched in the 2nd Quarter of 2012.

So what should I do?

First try a different Prime Like stated above.

Then I would pull my heat sink an look at the thermal grease. It should be thin and not going over the edges. Also I might look into getting an after market cooler. I like the Cooler master Hydro but there are many good ones out there. Look for reviews on Google.

I do have a H60 and I just re-applied thermal paste is good

 

[JimF_35]

If you have an H60 I am wondering if the pump is running at full speed. Do you have the pump plugged into the fan header or direct mulex to the PSU?

Thank you for the information! This seems a little rough to do. I have the new prime 95 and restored the UEFI Defaults. You asked for the ambient temperature by that do you mean standard temps not stress testing on my normal core clock with defaults restored?

 

[JimF_35]

the "ambient temperature" is the temperature of the room.

The latest version is 28.5. The version in your screenshot is 27.9. Please do NOT use these versions. All you need to do is download and run 26.6 instead.

Run ONLY Small FFT's for just 10 minutes.

About ambient temperature, here's some information:

Standard Ambient temperature is 22C, which is normal room temperature, and is the reference value for Intel’s Thermal Specifications. Knowing your Ambient temperature is important because Ambient directly affects all computer temperatures. Use a trusted analog, digital or IR thermometer to measure Ambient temperature.

Here's the temperature conversions and a short scale:

Cx9/5+32=F ... or ... F-32/9x5=C ... or more simply ... an increase of 1C = an increase of 1.8F

30.0C = 86.0F Hot
29.0C = 84.2F
28.0C = 82.4F
27.0C = 80.6F
26.0C = 78.8F Warm
25.0C = 77.0F
24.0C = 75.2F
23.0C = 73.4F
22.0C = 71.6F Standard ... or ... 22.2C = 72.0F
21.0C = 69.8F
20.0C = 68.0F Cool

With conventional air or liquid cooling, no temperatures can be less than or equal to Ambient.

As Ambient temperature increases, thermal headroom and overclocking potential decreases.
