i5-6600k Overclock questions

post #1 of 8
Thread Starter 
So I am trying to overclock a my i5-6600k cpu.

Current OC 4.6ghz@1.36vcore
Current Max temps are 65c at load.

Now when I go to bump the multiplier up to 47 I can't pass any type of stress test. I have increased vcore all the way 1.4v and still no avail. Am I stuck with my 4.6ghz, which Is still a great OC. I just don't understand why I can't get to 4.7ghz even with 1.4vcore. Guess I had a bad silicon lottery.

Any insight would be great on how to possibly further my OC

Yea it sounds like 4.6 is your max. even if you slam more vcore it doesnt mean you will hit the higher clock. its generally a pretty hard ceiling once you hit it. if at 1.4v it isnt holding 4.7 then 4.6 is your max. so just tweak your 4.6 as tight as you can. still a super solid OC though. my 4700k wont even hold 4.6 stable right now. i had to back it off too 4.5 until i can get it on water. 4.6 could only be held at like 1.38v and higher and i wasnt happy with the temps on air. so technically, you lost the lottery, but overall you really didnt do too bad. hope this helps biggrin.gif

I experienced the same for my 6600k. 47 multiplier just doesn't work , I tried 1.408v , LLC 4 LLC 5.
All error on x264 stresstest.
It didn't give me any extra points in chinebench R15.

Backed down to 46 multiplier 1.360v LLC 4 for 2 months before tried the bclk OC , now 46x 101.5mhz 1.376v LLC 5

It just bothers me with so much temp headroom. 46 multiplier at 1.36vcore and not even a 1.4vcore can run 47. I'm cooling with Hyper 212 EVO which is a decent cooler but by no means top of the line for air. I think one core hit 67c with my current OC. It was so promising and then poof, nothing. Would a delid, make any difference. I've read it allows for a lesser vcore needed to run the current OC, but I don't wanna take a chance if I can't get anything more from this chip.

I'm kind of disappointed with skylake, because there are a lot of i7 4790K's that can do 4.7 GHz at 1.30v and yet the i5 6600K struggles to get it stable at 4.7 GHz 1.3v-1.4v. Even 4.6 is pretty bad, need 1.36v. Maybe it's just me.

Eh not really. the problem is internally cpus tend to hit overclocking walls hard. like as soon as you hit the cap the next OC mark might be at an ungodly voltage or just unattainable. A delid wouldnt immediately give you a better overclock, it would aid in temp control assuming you were having issues keeping it in check but thats generally it. Its just simply silicon lottery and you got a 4.6 max chip. solid by all means, i can get the disappointment but there really isnt anything you can do about it aside from buy another chip and pray or go to silicon lotterys website and purchase a binned chip for a garrenteed overclock mark.

Yea, the new architecture doesnt really seem to do aswell at all with high overclocks, Silicon Lottery hasnt been able to find any 6700k's that do over 4.8 either. the 6600k so far has better results overclocking then the 6700k. my 6700k is unstable at 4.6 unless i put the voltage to 1.4v but my issue then was temps doing IBT stress testing. maybe get our hopes up for kaby lake later this year? lol

Early in skylake's release it's already known from Asus overclocking guide that the vcore fed to skylake cpu is not the real voltage the chip is eating, thus invalidate any apple vs orange comparison between haswell vs skylake

I prefer to compare how high the chips go stable within "safe voltage"
