Overcloking Intel i5 4670K with Hyper 212 evo

[Spov]

Hi,

This is my first time overcloking. What should I try and overclock to with an intel i5 4670k + Hyper 212 evo cooler?

Also my idle temps are (checked from Bios) :
* Cpu = 30 - 35 Degrees
* Motherboard = 25 - 30 degrees
Are these idle temps alright ?

Best regards

Those idle temps are good, i get similar temps with my fx 8350 and the same cooler. Download Hw monitor so you can measure your temps while in windows, this way you'll know if anything is getting too hot

Hi,

Thanks for the reply. The Asus suite 3 already comes with utilities measuring your temp's in windows. Also what do you think I can overclock to?

Temps are about average, depends on your ambient temperature as well. You could likely OC to 4.2 stable and have relatively good temps. Don't forget about your voltages either.

Go for 4GHz at first, then run prime 95 to get your cpu at full load and check what temps you get. If it's still stable then maybe try 4.5 GHz but i wouldn't go any higher than that

I'd also consider just trying a quick high clock to test your chip. Something in the range of 4.4/4.5ghz at about 1.250 volts. If you can be stable then that gives you a good starting point and also lets you know if you chip is above/below or just average.

I have the same chip/cooler in a MSI z87 g45 motherboard. I tried 4.4ghz at 1.250 and I would boot but instantly crash as windows loaded up, then I pulled back to 4.3ghz, booted into windows, ran the intel tuning utility stress test and BSOD came up within 10 mins, then I went down to 4.2ghz, tested and it was fine. I slowly moved the voltage down, got it to about 1.220 stable, any lower at say 1.210 and it will BSOD after a bit of stressing.

Thats with leaving the ring/cache ratio to its default of 3800 (38x) mhz. I'd say my chip is average at best as I seen people claim they can get 4.4 or even 4.5ghz at voltages well below 1.200. 1.250 voltage was my treshold as I did not want to run at or too close to 1.300 as this will be my 24/7 clock.

As for temperatures running at 4.2ghz at 1.220 volts, I'm in the 58-65C under load and highest I've seen it go is 68C. Idle its around 40C.

Also just a heads up, with haswell, if you use adaptive voltage, certain stress tests will pull extra voltage and may overpower your cooler. I know its been said Prime 95 does so, I used intel burn test which did it for me. I had I believe set voltage to 1.220 when I was testing, I had CPU-Z open and saw my volts shoot up to around 1.320 and my temp shot up to 96C real quick and then I stopped the stress test as I did not want to hit 100C.

This is good to know... I actually gave up OCing my 4670K to 4.4GHz on the Hyper 212 evo due to this issue. I had no idea Prime added Voltage during burn-in. Now I'm no longer terrified to OC to a stable 4.2 lol
