Skylake Overclocking Guide [With Statistics] - Page 9

post #81 of 11364
Well, I've been running at 4.8 GHz for about a week now without issues. Playing games and such. Ended up raising the voltage by 0.01 twice after a BSOD from a starting value of 1.450v.

I would do overnight stress testing but the temps are a little bit out of control with just a D14 for cooling.
Will probably finish the water loop sometime this week for some nicer temperatures. After having finished that I'll see if I can push it further and will dive deeper into the BIOS.

For Darkwizzle

Username: shredzy
CPU Model: i7 6700K
Base Clock: 100MHz
Core Multiplier: 46
Core Frequency: 4600MHz
Cache Frequency: 4000MHz
CPU VID: 1.325V
Vcore: With manual voltage set, 1.328V at load.
Cache Voltage: N/A with Skylake, Vcore is tied with Cache Voltage
Cooling Solution: Corsair H100i GTX
Stability Test: Realbench, 8 hours.
Batch Number: Malaysia (Purchased in Australia) L523B541
Ram Speed: Stock was 2666MHz 16-18-18-35 2T, now overclocked to - 3000MHz, 16-16-16-36 1T
Ram Voltage: 1.350V
Motherboard: ASUS Maximus HERO VIII
LLC Setting: Level 5

So wanted to note to others overclocking on Skylake, with memory you NEED to alter your VCCSA (System Agent Voltage) for high memory clocks. Due to Skylake supporting 2133MHz DDR4 anything over that is considered a overclock for it. For example, when I clocked my ram to 3000MHz, 16-16-16-35 1T, 1.35V and ran memtest, I got some errors in the test. So I jumped my System Agent Voltage (VCCSA) from its stock 1.0500V to 1.0750V and wooo! Fully stable on memtest after 8+ hours (4 passes). So don't just assume your getting errors in memtest cause your DRAM voltage isn't high enough, play around with the system agent voltage abit. For LLC settings I recommend Level 5 on this board to be the real sweet spot, hardly any vdroop and spot on with voltage at load.

Also wanted to mention that I went through 3 different motherboards on this platform. First was a Asrock Fatal1ty Z170 Gaming K6+, second Gigabyte GA-Z170X-Gaming 7 and lastly ASUS Maximus HERO VIII. I have to give a BIG props to ASUS on their motherboards, I had ZERO problems with it and its UEFI is absolutely outstanding, its like they actually cared about their layout/design and features with this board, they really care about overclocking and getting the most out of your CPU. Was a real pleasure playing with this motherboard, I really recommend others to go with ASUS for their next builds, they have a permanent spot in my heart now. If you aren't planning to overclock, doesn't really matter what you go with.

I've tried 4.7GHz but it was taking quite abit more voltage to pass just a 15min Realbench stress test, was at 1.39V from what I remember just to get pass that point so I'd be thinking id need around 1.40V to get it stable. I've also got screenshots of my BIOS settings if anyone requests them.

Pics of my build if anyone is interested

What are your temps dude? Same setup I am aiming for. Are you delidded? And also what paste you using?

As you can see, some like intel XTU and HWinfo show that the core is at about 1.42V, a little high from what should be fine, but the ASRock tool that should read from the bios and CPU-Z show that the core is at about 1.28V, which sounds fine.

Which reading should I trust?

Is the voltage set to auto? if so it might increase it as you raise the multiplier. I've heard reports that CPUz needs an update before it will report Skylake voltages accurately. To be on the safe side for now I would assume the higher value is correct, If you feel the auto voltage is too high you can always lower it manually. Is there a voltage offset control?

I wouldn't add my settings to OP yet, trying to experiment with adaptive voltage currently. With same LLC setting on Level 5, turbo voltage set to 1.325V and offset left on auto I'm getting slightly higher voltage recordings while playing games/doing other tasks (not AVX). Got a BSOD last night while watching streams, was a d1 code so think it has to do with my ram stability, I bumped my system agent voltage 1 notch to 1.08750v and reran memtest last night again for 9 hours. Ill see how it goes today.

EDIT: Memory is unstable as hell even tho it passes memtest no probs....reverting back to my XMP profile 2666MHz 16-18-18-35 2T 1.20V and see how it goes.

Thanks matey,

Will be giving it a shot tonight if not Wednesday night when I'm off work.

I will be doing the same thing and leaving the Ram XMP profile as it is for now and tweak it later

Hi Guys,

Thought it was time to OC my 6700K, and wanted to thank you for the information provided for this new platform.

Need to do a few long (8 hours) stress tests, just been checking where I might be at, running the ASUS Realbench 2.41 @ 15 mins.

VCore according to ASUS sensor is 1.328, HWiNFO64 VID 1.255 ~ 1.309 (Same in CPU-Z)

BCLK 100MHz Ratio 47 (BIOS core voltage manually set at 1.285) with everything else on Auto...

Seems it Auto ups the voltage to 1.328, and VID (which I believe is what the processor requests, but doesn't necessarily get) fluctuates around that manual setting...


Same MOBO as shredzy smile.gif

H110i GT cooler Temps around 60 degrees

RAM at default, but will try XMP soon.


Might also try P95 for the heat too.


What else would you recommend?

Also do your voltages on VID fluctuate? and what does HWiNFO say for VCore on the ASUS sensor?

Max was 77C on hottest core after 8 hour Realbench stress test. Not delidded and using MX-4 with line application.

EDIT: Updated my settings as well (just changed ram settings) http://www.overclock.net/t/1570313/skylake-overclocking-guide-with-statistics-wip/60#post_24330821

Hello all, I just used AI Suite to automatically find out the overclocking potential of my 6700K on Maximus VIII HERO. But I am now quite frustrated with Vcore.




I was told that the CPU has been automatically overclocked to 4.8GHz with 1.398v max Vcore after running 5-way optimization. But the Vcore readings from CPU-Z and AI Suite differs...Which one is reliable???

Thanks for your quick reply. Just noticed that the ROG version of CPU-Z is out-dated althogh its official website claims that it is version 1.73.

Does Skylake CPUs have much higher VID than Haswell??? Mine is read 1.372v in UEFI and 1.369v - 1.376v bouncing in CPU-Z...I noticed that generally 6700K has around 1.3 to 1.4v of VID which is much higher than 4770K with around 1.2v...

EDIT: It's quite strange with VID readings in UEFI. Sometimes I saw 1.296v and sometimes I saw 1.372v...A HUGE difference handlebarssmiley.png

Yes it does, if you read this thread, everything stock in BIOs, people reporting their vcore jumping around 1.3-1.4V, I occasionally saw it hit 1.44V at a point. This chip seems to take more voltage than haswell, its cooler as well at higher volts over haswell.
