been asked by sister in law to overclovk her 8700k on a STRIX gaming f board full water loop
What volts should be a starting point for say 4.7Ghz as not done any oc for years
 
i dont have a 8700k but i have it's little brother the 8600k and i've been running it at the following speeds and volts

4.5ghz @ 1.245v
4.8ghz @ 1.285
5.0ghz @ 1.315v
5.2ghz @ 1.360v (but ran insanly hot even under water)

correct me if i'm wrong but doesn't the 8700k turbo up to 4.7ghz anyway, if your using a asus board it will have multicore enhancement enabled in the bios which will allow the 8700k to turbo all 6 cores up to 4.7ghz anyway, you can manuly set the cpu multiplier at x47 just dont go too crazy with the volts i'd say someware in the region of 1.265-1.275v at 4.7ghz for your chip should be fine, but you'll have to test and if its not stable just creap up the volts until it becomes stable and definatly keep an eye on temps if they start to spike you may have to delid to regain temp control, and if deliding dosnt work you unfortunatly you've lost the silicon lottery :(

hope this helps

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!
 
by the looks of your overclock filipe i recon its the processor running at it's max turbo speed the 8700k has a base of 3.7ghz but will turbo up to 4.7ghz, the volts seem super low but your max temp does seem on the toasty side, have you applied a x47 multiplier in the bios, either way if the chip is stable at 1.2v then leave it where it is and enjoy, if the load temps exceed 85 degrees i'd stop and look at delidding before proceeding with anymore overclocking
 
should have mentioned my 8600k is at 5.1ghz running at 1.325v seems stable in some games but other crash to desktop i think i'm almost there getting it stable and my temps are around 74 degrees, thats after a delid as well, bought a delid die frame off ebay to run the chip naked to see if the load temps will drop from 74, after it arrives i'll post my results

dam you have a good chip, 1.2v is super low but as always keep an eye on those load temps if it gets too hot look at deliding :D
