Overclocking 8700 to 4.7 @ 1.20v normal??

[Filipe]

Hey guys, I am super newbie to this stuff literally started today! I have never OC'ed a CPU in my life, but with youtube everything is possible these days.
I have a I7 8700K, Gigabyte Z370 16RAM 3200 and watercooling, so my OC so far is:

Clock = 4.7
Vcore 1.20 (YUP that's right...)
C States disabled
XMP enabled to 3200
VCore Load = TURBO

So far the temp normal = 33C under stress 78C

Using the following benchmark tools:
Cinebench
Prime95
3DMarks
Monitoring using HMonitor

I didn't see much difference between 4.7 and 4.9 so decided to leave it at 4.7 to be on the safe side. My question is from all I've seen out there 1.20V for a 4.7 OC seems super low. Is this normal? Or should I bump it higher? Also, do I really need the C States disabled (if they are enabled I don't get as much performance).

Thanks in advance guys!

I’m running 4.8 on all cores @ 1.2 with MCE, - adaptive and LLC 6. When it’s clocked down it’s running some seriously low voltages.

Do you also have all C States disabled?

All the power saving is fully enabled.

if your stable! then leave it and carry on, the lower the voltage the better! sounds like you have a good chip, wonder if you could push 5.2ghz

have 5.1ghz on gigabyte ITX board, 4000hz ram , uses 1.355 voltage when underload and 360 Rad with silent wings cooling it down , 40-50c gaming, 88c rendering
