Is my CPU temp safe enough? (Haswell 4770k OC to 4.2)

Hey guys, I'm ocing for the first time and I need to know if this temp for my haswell is too hot for daily use.

Specs:
i7 haswell 4770k
Evo 212 cm cooler
Msi z87 gd65
8gb gskill ram 1866 MHz (running at 1600?)

The temperature is idling around 39-40 and the p95 stress test is pushing it upwards of 79....sometimes a little under that.

Frequency is 4.2
Ring ratio is 4.1
CPU voltage is 1.050
CPU ring voltage is 1.025


Feel free to ask me questions if I need to elaborate on anything else.

  1. Hello,

    I've just OC'd mine to 4.2GHz using a similar board - MSI G45.

    Put the frequency to 42
    CPU Voltage Core - 1.175
    Cores - Fixed mode from dynamic.

    Leave everything else to auto. My idle temp was around 28-30 degrees and under stress using AIDA64 60 degrees.
  2. I'll try it out, thank you!

    I didn't mess with the CPU ring ratio and just left it at 3.5, and I changed the cpu frequency to 4.2 with a fixed CPU core and everything else is auto. It idles around 31-32 and under full stress load it's setting at 65ish. Not too bad huh? Although...shouldn't my CPU ring ratio be right under my frequency for the gd65?

    Yes that is perfectly fine! Quite good tbh.
  5. Thank you for your help. One last little bit, for future reference...when should I start getting worried about my CPU's temp getting too hot?

    I would say around 80 degrees is the danger zone, people seem to be ok with 70 degrees but I would say 65 degrees is where I would like to keep my temperatures at under full load.
