Need Some Help I7 8700K

Hello, i need your precious advices from you guys! I have the 8700k since one years.. so i am looking to overclock it a bit. Overclock is new to me and I can say that 4.7 on all cores with an acceptable temperature like 70C or less in full load is my goal ideally. I do not try to push him to the maximum.

I have the asrock z370 killer sli/ac with a cryorig h7. Right now i am testing this on bios: i have put 46 on all the cores except the first i leave it at 47 ( not sure why i do that.. with the MCE at stock i never see it at 4,7 only 4,3 on all cores. The cpu voltages is on offset mode -105 ( i wanted to keep a lower voltage in idle ) and everything else is on auto.

I have tested it with stress test at aida64 and real bench for 15 minutes is look pretty stable, i still watch it if I need to increase the voltage. CPU Z give me on full load 1,200V and i have see it for a few seconds at 1,21V. For the temps in idle is 29C to 30C and in stress tests I have got 70C at 78C max, he often turned between 72C at 76C. The voltage and The temps is good for my speed? In the long term particularly is safe ?

Other question: I know the noctua nh-d15 and cryorig r1 is better than cryorig h7 and is the king of air.. and beats many AIO , if i get this one ( i am ok with that and is will fit in my case ) I will be able to lose 10C or more on full load at least on my current settings? it would be possible to turn the 4.7 in my current temps?

Last thing i have 32GB of ram ddr4 on 2400 mhz , 2 ram of 16GB that I put in dual channel and i have enabled the XMP profiles in the BIOS. The task manager of windows 10 is tell me 2400 mhz but in cpu z tell me 1200 i saw many peoples said it's normal he has to multiplied by 2 .. so 2400.. i just want to be sure. is fine?


Thanks guys!

Sory to tell you but thats a pretty mediocre PSU but no wonder when HEC is the OEM
Many of the capacitors are cheap second rate chinese Teapo capacitors rated at only 85c

Its not horrible or bad but its not great either so thats why it was cheap

Well i know is not made in gold but is do the job. Never had a problem with. On my old build i having the 550 Master watts with a i7 3770k after five years still working fine and the power is fine. I have see People with a more cheap psu than this.

So what you suggest for my questions?

CPU-Z shows you the actual RAM speed, not effective. Task Manager shows you effective. DDR is double data rate. Both are right.

H7 to high end air (Grand Macho RT) got me worthwhile drops on my old 6700. If you'll get "10c or more drop on temps" depends on too many factors for anyone to answer that, but maybe.

15 minutes is not nearly long enough to determine stability.

You had the H7 on your i7 6700? and you have changed for Grand Macho RT, what interesting results did they give you? 10C less?

Thanks guys!
Your doing just fine. keep pushing the overclock up to 1.4v and under 100c with stress testing whichever comes first.

wingman99: Okay and for the cooler? it's worth it for the temps to change eventually at noctua nh-d15 or cryorig r1 universal ?
