Are these I7-4790k temperatures normal?

Dragalos · May 6, 2017

When I play games it usually is around 60°C but sometimes it spikes up to 70-78°C. I dont know if these temps are normal or not. Reapplied thermal paste around 6 times already.
When I run the CPU test of TimeSpy my CPU reaches around 80°C and in AIDA64 it goes up to 77°C after around 30 seconds.
Voltage under load is 1.299V.

My CPU cooler is Cooler Master Hyper 412S and the case is Cooler Master HAF912 Advanced Midi-Tower.
Motherboard: MSI Z97-G43
RAM:16GB Kingston HyperX Savage
Power Supply: XFX TS Series 750W
Btw I havent overclocked the CPU.
If you need any more info to help me just ask.

Thank you in advance.

Running at 1.3v is WAY too much juice for a stock 4790K. You should be around 1.1x under load. Are the BIOS settings in your motherboard all set to auto? That kind of voltage would have your CPU running at 4.5GHz or more (and that would be normal temps for that with your cooler BTW overclocked).

I guess they are set to auto as I never changed anything apart from activating XMP.
What do I need to look for? Like what setting shouldnt be set to auto?

Dragalos :

Here's a PDF download link to your manual: https://www.msi.com/Motherboard/support/Z97-G43.html#down-manual.

Look starting at page 3-20 and make sure every setting is as they state it is under the voltage topic. I've never heard of a motherboard overvolting out of the box as the factory BIOS settings are everything being on auto or default.

With that said, you definitely have something wrong with the motherboard controlling the voltage. Is this a new build or did this problem just start happening and you've had it a while?

Dragalos · May 6, 2017

10tacle :

I dont know how long it has been but I dont remember it having it before I selected an XMP profile to get my RAM running at 2400MHz. I've had this build since December 2015.
I'm gonna check the settings in the BIOS now and then come back if I find something that isnt like the manual states it should be.
Are the sites 3-20 to 3-22 enough or do I need to check more?

It would be the best to manually overclock it to 4.4 Ghz, that way you will get lower temps and less power consumption.
You can use this as a starting point

Dragalos :

Well that's where I would start since you said you are not overclocked (running 4GHz stock on all four cores). If everything winds up being set to auto or default on the voltage options, then you have a motherboard voltage controller problem and need to override it with a manual Vcore setting.

Dragalos · May 6, 2017

10tacle :

I've checked page 3-20 to 3-22 and everything is the same as in the manual.
In other forums I read that they have the same stock voltage for their i7-4790k.
Under load the cores are running at 4.4GHz.

10tacle · May 6, 2017

Dragalos :

Again, that is not a normal voltage for your CPU being stock. Also, 4GHz is the stock speed on all four cores. The Turbo boost to 4.4GHz is officially only on one core by default by Intel unless manually overclocked to hit all four cores or the motherboard itself does it (meaning that motherboard maker is out of Intel's official specifications for the chip). Something is not adding up here.

10tacle :

for me all 4 cores are running at 4.4GHz under load but when all 4 cores are under load they should be running at 4.2GHz right?

10tacle · May 6, 2017

Dragalos :

It's your motherboard then. For whatever reason, apparently MSI is doing an "auto tune" of sorts which almost always use more voltage than necessary. At all for cores at 4.4GHz you should be in the neighborhood of 1.20 volts +/- depending on how good or bad your CPU silicon lottery is. I used to have a link that showed Devil's Canyon i5 and i7 voltage reports from users but can't find it. Look at my sig and CPU-Z screenshot - I'm running my i5 4690K at 4.7GHz with 1.297v.

Get in there and manually set your Vcore to say 1.20v and see if it runs under a stress test. Then gradually reduce it in increments of .005v (1.195, 1.190, etc.) until you get the lowest voltage that still keeps your CPU stable. I am not familiar with MSI's BIOS (I only use ASUS) but they should have a setting for CPU voltage to be on "adaptive" or something similar which means the voltage will go to minimum when not in use then max out at whatever setting you have entered for Vcore.

I dont know how to post a picture if you tell me I'll post a picture of the settings in my BIOS and you tell me which setting to change as I'm a real beginner when it comes to changing voltages in the BIOS. ^^

Edit: I know how to do it now
Here's the picture:

Well I'm not familiar with MSI motherboard BIOS settings (every motherboard is a little different) and honestly would not feel comfortable guessing at exactly which settings to do. I'd recommend getting on MSI's support forums and get the real experts familiar with MSI BIOS "language."

I'd not want to tell you to do a setting that I "think" is the correct one and then it wind up being the wrong thing and ruin your system. The only thing I can do is give the basic guidelines on what needs to happen. Sorry this is not the answer you are looking for but I hope you understand! Maybe an MSI user here will get on and help since this thread is pretty active.

Dragalos · May 6, 2017

I posted a picture above and I'm pretty sure it is the CPU Core Voltage

10tacle · May 6, 2017

Ah - so at idle in BIOS it's showing 1.112v on auto. That's still high. That would be the line to change to manual and then manually enter a voltage. I do not see where there is an "adaptive" voltage setting which concerns me. But you can start with just testing the core voltage.

10tacle · May 6, 2017

I think I just figured out what the adaptive voltage setting is:

CPU Phase Control [Auto]
Controls PWM phase proportionally to the CPU loading. If set to "Auto", BIOS will optimize the CPU PWM phase automatically.

[Auto] This setting will be configured automatically by BIOS.

[Normal] Sets the normal power phase profile for CPU, it could provide a stable system performance and effective power-saving capability.

[Optimized] Sets the optimum power phase profile for CPU, it could provide the system with an optimum power-saving capability.

[Disabled] Disables the PWM power phase switching feature.

I would try both "normal" and "optimized" settings here and see what the voltage does both during idle and under load. It's like learning a new language when dealing with different motherboards.

Dragalos · May 6, 2017

10tacle :

At the very top there is an option to switch into advanced mode after that there is an option for ""Cpu Core/Ring/GT Voltage Mode" where i can select adaptive, manual and auto.

10tacle · May 6, 2017

Dragalos :

Okay so you want to set a manual Vcore (CPU core) voltage and then select adaptive. Again, adaptive *should* only go as high as your manual Vcore setting and then throttle down volts while at idle. This is the way ASUS boards work anyway. For what it's worth, my ASUS Z97-AR board never pushed my 4690K out of spec while at default settings.

Dragalos · May 6, 2017

10tacle :

This is what it looks like when I change to Advanced mode:

What should i change the voltage to? Is 1.2V enough or is it too low already?
Also you said earlier that it is on 1.112V on idle(what it says in the BIOS) in CPUID HWMonitor it says its 0.716 while idle.

Karadjgne · May 6, 2017

Cpu voltage and core voltage are different and will show as so under different software/bios etc.

Dragalos · May 6, 2017

Karadjgne :

OK thx found another entry in HWMonitor "CPU VCORE" when idle that goes to 0.056V i dont know if this can be correct

My 4790k is running at 45 multi at 1.200v Vcore on override mode and 40 multi for ring ratio (stock) at 1.80v. With a Cryorig H7 and fans at full blast, it will still jump past 80C within 30 seconds of launching a small fft P95 torture test, regardless of ambient temps, blazing past 90C shortly thereafter, pun intended. Often times, it'll thermal throttle within a few minutes and continually downclock to 3.8ghz. On the H100i custom loop that I macguyver'ed yesterday, it still pegs 83C on the hottest core at the same 45 multi. Damn H100i pump is so weak. I miss the pump speed control we used to have on the old Corsair Link. I think I lost the silicon lottery and/or the IHS TIM lottery. Corsair Link reports that my fluid/block temps are abnormally low compared to CPU temps. I've tried 3 different TIM's and countless application methods at this point. I think my CPU is just plain hot.

Auto voltages on my motherboard put my load voltages at 1.4V flat, and it overpowered every cooling solution I threw at it, including an AIO dunked in an ice bath, a la AwesomeSauceNetwork a.k.a. Bitwit.

I'd start with a multi of 44 and override mode Vcore of 1.95, and lower the Vcore by 0.05 for every stability test you run, until you hit the Vcore lower limit of stability. Or set the Vcore somewhere between 1.2 and 1.25 and just see how fast you can run the thing.

Oh, and make sure you have ample cool fresh air hitting the CPU cooler. Helps rule out variables like the CPU cooler sucking up super hot GPU exhaust.

What does the override mode do?

I went into the BIOS and tried to change the voltage but it doesnt let me. Do you know why that could be?
