PC crush caused by high CPU voltage?

[z281325341]

I built my own PC and recently been getting blue screens while playing planetside 2 at first i thought its GPU problem then i looked up on forums and i found out that it is a CPU intensive game and the corsair link software says my CPU reaches 70c sometimes and my GPU is always at around 75c. Anyway i downloaded CUPID and it tells me my CPU has about 1.85v is this too high so its causing CPU to be too hot? and what should i do?

Appreciate your helps in advance.

My Spec:
CPU and CPU cooler:I7 4790k (stock speed) cooled with with corsiar H100i
Motherboard:Asus Maximus VII Gene
Graphics card:Asus DirectCU 2 Overclocked GTX 780TI
RAM:Corsair 16gb ram
Storage:Crucial SSD 128GB as boot drive
Western digital black 1tb
PSU:Corsair RM1000

From what I know, the top voltage for a CPU is around 1.5V.

Based on that and what you're writing I'll give you a quick scenario:
-you're playing the game,
-the game is asking for resources,
-the CPU voltage is kicked up to 1.85V (that's kinda huge) to do an overclock,
-the CPU reaches 70 degrees and then you get BS.

What I'm guessing is that the CPU actually reaches 100 or more and since the system tries to avoid being damaged, it automatically goes to BS. You don't get to see this because stopping the system from melting has a higher priority than giving the temperature info to CPUID (or any other third party app) 😛.

I'm not 100% sure but it seems like this is the issue. It's probably caused by some automatic (or manual?) Bios or third party app overclocking. Good luck finding out which and turning it off 😀.

Thanks for the reply, forgot to mention i checked the voltage when i wasnt applying any loads to my pc so it was idle but the voltage was still at 1.8v and i returned everything to stock settings. :/

Are you checking in Bios after setting the stock settings?

I just checked the bios as you mentioned, the strange thing is that on my bios Vcore says aroud 1.1 however when i boot in my system, CPUID says 1.84 which is exactly the initial input voltage shown on the bios, this is really confusing.

You have an application that's setting the voltage higher. I'm not sure which one but that's the issue. Might be a virus, might be anything else. I don't have an Intel and I'm not too familiar with them or how they work. It may be a stock feature of theirs to automatically overclock under a lot of stress (supposition). You'll have to Google about Intel and this behavior and see if you have any app installed that might even remotely resemble an overclocking app.

At first I thought that this might be a bad cooling issue but then I saw that you have the Corsiar H100i which is an extremely good cooler!

To me it smells like either a virus or a "feature" of Intel (leaning towards the first). If you don't find a solution then ultimately reinstall Windows and see if you're getting the same thing in the same scenario.

Good luck my friend 🙁 !

Ok thanks a lot for helping, I will try to look for other solutions from intel support
