Okey.. I have now done some more testing with the LLC on level 4.

Before I changed to LLC 4.. I had an stable 4.6Ghz @ 1.40v, ring Auto, no XMP. Did 50 loops, 16 threads and normal.. in custom x264 stress.
Which you know from earlier post.

So now I started to lower the voltage after I changed to LLC 4. 4.6Ghz @ 1.39v + LLC 4 + XMP, was no go. Crashed after about 6 loops.
What I did then was that I went back to the stable 4.6Ghz @ 1.40v (no XMP), but this time I used LLC 4 aswell.. and it worked just fine, 50 loops, 16 threads, normal.

Tried today again with failure.. this time 4.6Ghz @ 1.39v - LLC 4 - No XMP. Not stable.

With all this done, I watched the voltage closely as I have change the LLC which changes how it works with voltage etc.

When running with LLC on Auto and setting the UEFI/Bios voltage to 1.40v (4.6Ghz). I get an reading in HWiNFO64 showing that current vcore is about 1.42v, maximum = 1.44v and average = 1.42v. So with the LLC on auto I get and "much" higher voltage then used in UEFI.

So now when I'm running with LLC 4 and the voltage in UEFI set to 1.40v (4.6Ghz) I get the current = 1.37-1.39v, maximum = 1.408v and average = 1.38v. It's sometimes going up to 1.39v sometimes at current reading, but only for 1sec at it's peak.

My try at 4.6Ghz @ 1.39v + LLC 4 is getting current voltage at 1.37v, maximum = 1.392v and average = 1.38v.
I'll add two pictures showing this.

Right now.. I pretty much have no clue what to do next. I dont belive just yet that I can't go lower then 1.40v on my 4.6Ghz overclock.
Can I use some other level of LLC that might help? Or am I missing something? I'll take all the help I can, Thanks.


4.6Ghz @ 1.40v - LLC 4 = STABLE



4.6Ghz @ 1.39v - LLC 4 = NOT STABLE

Try 1.408v in bios first with LLC4, and if still unstable then try 1.424v
You will crash if the minimum vcore in windows is too low during load. Watch the vcore when stress testing, and observed if crashes occur when it drops to too low a voltage (or stays at that low voltage for "too long"). You will have to increase voltage in bios to keep above that level in windows during load, if you want to keep the same LLC level.

Btw, 4.1fps for 6700k at 4.6GHz feels abit low, could be its barely stable & more vcore needed.
Can you check others' results? I think people are getting around 4.5-4.6fps for 4.6GHz, but I'm not sure.

Hi,
I've still problems with my processor temps. While playing Witcher 3 (after ~15m) or using IBT (after 2m) it reaches 80°C.

My current settings aren't so high as your (at your settings, e.g. 1,35V and 4,6Ghz I'd burn my processor).
CPU Model: I7 6700k (delidded with arctic mx-2 between processor and heatspreader and between heatspreader and Kraken X61 LC)
Base Clock: 100.00
Core Multiplier: 43
Core Frequency: 4300.00
Cache Frequency: 4100.00
Cache Frequency: 41
Vcore in UEFI: 1.27 <- Adaptive with +0.03 offset (hwmonitor and cpu-z show only VID, not vore)
LLC Settings: lvl 5
FCLK: 1Ghz
RAM Speed: 3333mhz (I bought those)
RAM Voltage: 1.36V (UEFI: 1.352)
VCCIO 1.15V
VCCSA 1.15V
MOBO: ASUS Z170 PRO GAMING
Turbo: enabled (when I disable it, cpu-z shows stock 4,0ghz)

I tried with to raise or lower IO/SA Voltage, disable or enable XMP, lower Vcore to e.g. 1.23V (unstable as hell), set offset to auto, set voltage as manual, change LLC to 1 or 7, reapply thermal grase, update UEFI to latest version etc. Nothing works.
Do you have any idea what's going wrong?


edit: I resetted my UEFI (ram to JEDEC 2133, voltages auto etc.)
and after a short period with Intel Burn Test:

I'm feeling totally f...d by Intel. A man spends his hard-earned money for "unlockable" processor and receive that. Laughable.

I have a gigabyte board, not a asus like most of you.

when I set the VCORE in bios to 1.40, i will see 1.386 in CPU-Z. When I look at hardwareinfo64 or coretemp, i see VID and its way lower than 1.40, hell right now, vid is at like a 1.25.


is VID the true vcore, or am i looking in the wrong spor in hardwareinfo64?

your issues are temps. Not sure why your hitting 80c in the witcher at that low clock / voltage, im at 1.4v/4.6ghz and not delid'd and never see it go over 70c.

could be you used too much thermal paste or too little? heatsink not making good contact, or just a crap cooling solution?

Can it be possible that unlucky i bought worse "piece of silicon"?

I don't think that I gave to little thermal grase. When I delidded, I applied approximately the same amount of mx-2 (looked not much for me) but the temps were still high. I used computer entire next day (to let the paste "burn" and reach optimal properties) with benchs and games but it didn't helped. I cleaned processor and reapplied paste with more amount. The same.

I was thinking about my cooling system but it looks fine and it sticks to the heatspreader. I tighten the screws to the end. Nothing is loosely connected.

The only question is that, the liquid on it never reaches more that 35°C. I know that my radiator is big (280mm) but shouldn't temps be higher under load, when processor has 80°C?

MX-2 is crap between the heatspreader and die, you need to use a liquid metal or worst case something like thermal grizzly kryonaut.

Are you totally sure about that? I'm using mx-2 for years on multiple GPUs and CPUs, on my old, delidded ghraphic card (gtx 570) I had it between die and radiator (without heatspreader) and it worked perfectly.

Liquid metal is conductive. Won't it break something on die?

Also which one liquids metal could you recommend (performance and application)? Coollaboratory Liquid Pro should be fine? Not all are avaible in my area.

edit: Liquid Pro shouldn't be used on glin. Isn't die/heatspreader made from it? It looks that.
edit2: one guy here also applying mx-2 on die: (15:50): https://www.youtube.com/watch?v=XXs0I5kuoX4
