Critique My OC + Voltage Question

post #1 of 6
Thread Starter 
Hi,

I was playing around with OCing my new build today and I wanted to get your feedback on whether you think I'm pushing my gear too much. I don't want to do anything that is going to kill the longevity of my hardware.

Currently I set the multiplier on my I5 6600K to 44 so it goes from 3.5 GHZ to 4.4 GHZ. I also manual input a voltage value of 1.24 in my BIOS.

I've been running Prime 95 v 28.9 using a small FFT test for 1 hour with no errors. My CPU reached a max temperature of 76 degrees Celsius and tends to average ~70-72 in that 1 hour window. EVGA E-Leet is reporting a pretty consistent core voltage of 1.288V.

  1. Do those temps. feel too high?
  2. How does that voltage look?
  3. Does anyone know why the voltage under max load would exceed the manually input value in the BIOS?

Here is my gear:
  • I5 6600K
  • Corsair H100iGTX Cooler
  • EVGA Classified K MOBO
  • Corsair GS 600 PSU

max is 78, but thats not recommended for 24/7 use. if you want your cpu to last, recommended safe operating temp is 75

That's pretty warm, have you dialed back the voltage till instability to see if you can cool it down a bit? Not sure why your voltage is going higher than what you've set. Mine doesn't, I use cpu-z to monitor it.

not familiar with the i series or your motherboard, but c states or p states, voltage ofset , or v droop are all various settings in some bios'es which can cause the voltage to slightly fluctuate from a manually inputed voltage under various loads.

look for a bios feature like one of these and disable it.

that really seems like a hot running processor, considering you have rather low voltage and water cooling, but it is, what 4.4Ghz, so it does have the frequency behind it to create heat. im just surprised that it still makes that much heat with such low voltages.

So no one decides to help him but all of a sudden almost 8 months later the answers just start pouring in.

Better late than never thumb.gif Although help probably isn't super helpful at this point for the op it might help someone else.
