i7 4790k OC Help

[IVIazor]

Hey Guys!

I just have a few question regarding OC'ing my cpu, it currently runs at 4.3ghz while under prime 95 and i also have a hyper 212 evo cooler for it, i was wondering what would be a decent overclock for this, also also is there a crash course somewhere on how to do this on asrock mobos as i cant find a good tutorial anywhere.

 

Thanks in advance!

Overclocking is chip dependent so each chip varies on the amount of OC. Use Adia 64 for stress testing it will provide more accurate results and not overvolt. Keep your temps below 85C but basically increase the clock rate and so a short stress test. If it fails increase the voltage a little and try again, keep it below the safe 1.3V core voltage range.

4790k can usually hit at least 4.7Ghz, don't use Prime 95 on Haswell CPUs, use AIDA64 or Intel XTU to stress test.

I use nothing but xtu and mainly aida64. I have a special place in my heart for aida64 though.

Thank you all for your very fast replys, i just got it to get to 4.5 easily, but im looking at getting a liquid cooler soon, as my 212 evo is going to my friends pc, any suggestions?

H100i or h80i gt. I've had an h100i, noctua d15, and honestly the h80i gt is my favorite of all.

I used the guide over at Anandtech for mine.

 

I have 4.7Ghz @ 1.23v
Cooled by h100i
Ambient temp of ~20°c
Idle temp of ~29°c
OCCT load temp of ~70°c

 

4.7Ghz seemed to be my safe limit. After that I needed a huge jump in core voltage to get it stable at 4.8Ghz.

I use OCCT on a 5 min run to test them. Then move up.

1. In the BIOS, set the DRAM to XMP.2. Set the CPU to 4.0 GHz (40x multiplier) with CPU Core Voltage to Manual and 1.000 volts.3. Save and Exit, see if system boots to OS.4. If entering OS fails, go back to BIOS and adjust voltage by +0.025 volts and return to step 3.5. When in the OS, run the POV-Ray multithreaded benchmark and OCCT test for five minutes. If either tests fail, go back to BIOS and adjust voltage by +0.025 volts and return to step 3.6. Monitor temperatures during OCCT test. If the temperature is at the top of the users limit, stop overclocking.7. If temperatures are low, and both tests complete, then this CPU frequency/Core Voltage combination is stable and noted. To continue overclocking, go back to BIOS and adjust CPU multiplier by +1. Return to Step 3.
