I've seen several people asking about OC'ing the GA-Z170X-UD5 TH, so here is my settings.

Stable Overclocking The GA-Z170X-UD5 TH to 4.8 Ghz.

1st, Many Thanks To Jerivalu and his Installation Guide.

USE Jerivalu’s GUIDE 1ST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

BIOS Version F5.


DO NOT USE THE GIGABYTE OC TOOLS IN WINDOWS!!!!! USE ONLY MANUAL BIOS SETTINGS!!!!!

I STRONGLY SUGGEST YOU HAVE YOU HAVE A VERY GOOD CPU COOLER OR A HYDRO SYSTEM!!!!!


1. All settings are changed in the M.I.T. section of the Bios.

2. Go to Advanced Frequency Settings.
Change the CPU Clock Ratio to "47".
Change the Extreme Memory Profile to "Profile 1"

3. Go back to Advanced Frequency Settings, then Advance CPU Core Settings.
Change the Uncore Frequency to “46”.
Change the Turbo Ratio for each Core to “48”.
Go back to M.I.T.

4. Go to Advance Voltage Settings, then Advance Power Settings.
Change CPU Vcore Loadline Calibration to “High”.
Go back to Advance Voltage Settings.

5. Go to CPU Core Voltage Control.
Change CPU Vcore to “1.39v”.
Change CPU VCCIO to “1.150v”
Change CPU System Agent Voltage to “1.250v”.

6. Save and Exit Bios saving new settings, reboot and go back into Bios.
Go to M.I.T and you should see the changes on the main M.I.T. screen.

Anything above these settings caused reboots or lockups in OS X and BOSD in Win 10.

So far, no issues in OS x or Win 10 while gaming for several hours last night.

Good luck and may the OC Gods smile upon you!

Everyone needs to use extreme caution on these overclock settings and also realize that no two chips are the same (what vcore works for you may not work for me for stable etc). For my chip the cutoff point was the 4.5 and 4.6ghz range for low vcore and low temps. On 4.5ghz I was able to have use 1.31 vcore while 4.6ghz needed 1.36. The v-core difference in temperature under load was over 15C different and personally I'd rather have my chip run cooler/near stock voltage than have the extra 100mhz.

Hey, Jerivalu. What version of Clover are you using? I'm running 3526.
I'm still using 3423 from multibeast and as I use this machine for work I'm erroring on the side caution- if it ain't broken....

Try using handbreak to encode a movie or video for say 1hr or more. Handbreak maxes your multi core use and is a decent way to measure stability; P95 in Windows is way too much and unrealistic for skylake.

I used terminal and ran this command 8 times to max all cores for almost 2 hrs with no issues. yes > /dev/null &

Cool. My settings are similar. My vcore goes up to 1.4V but with water cooling my idle temps are in the mid to upper 30's. Full load is a different story... Mid 70's. So far I haven't fried a cpu I my 7 years plus of OC. More often than not the PC becomes obsolete before the CPU gives out :). I don't use it 24x7 as I have othe low power PCs and Macs that do the everyday chores; this rig is for video encoding and processing.
My rig is as good as it will get; I wish I could get sound out my Radeon display port, but I think that is just asking too much. I am using a Bluetooth headset with a USB Bluetooth wart. Worked OOB.
Thunderbolt will be my next long term objective.

so ignore me
Sorry in advance for the newbie question.

I tried this guide on a new build (my latest build was last year on Yosemite) and I get the following error in verbose (-v) mode when trying to initially install. "This version of mac os x is not supported on this platform" I think it might be something to do with the USB stick but I have tried two USB sticks and all the rear USB ports.

Motherboard: Gigabyte Z170X-UD5 TH
Processor: i7 6700K
CPU Cooling: Corsair H110i GTX
Memory: 4 x Vengeance LPX DDR4 8GB (Tried with only one stick)
Graphics: AMD R9 290x (Tried with and without this card)
Storage: Corsair Neutron XT SSD 480GB
PSU: SeaSonic 1250W

Using the latest unibeast and OSX (11.11.5?) downloaded today

Any help appreciated :)

EDIT: Added PSU

Hi, I had the exact same message initially but it was because i was trying to install an El Capitan installer from September which did not support this hardware.. Are you 100% certain that you delete and redownloaded El Capitan from the app store today?

I formatted the intel SSD in OS X like you stated, I unplugged everything but the intel SSD that I formatted. I formatted the 167 GB portion of the drive to NTFS and left the 200MB EFI boot partition alone. Installed Windows 10, plugged everything back in and followed the steps to installed the NTFS EFI driver in OS X but I can't seem to boot from the Windows 10 partition through clover boot menu

I had a tough time with this, and I eventually figured out what I was doing wrong.

#1 - Start over. Reformat the window drive in OSX using Jerivalus' instructions. Shutdown and physically disconnect the other drive. In your "BIOS Features" make SURE you've set "Windows 8/10 Features" to "Windows 8/10" and NOT "Other OS". I did NOT use the "WHQL" option or enable "CSM Support". Save settings and reboot. Make sure your Windows 10 USB or DVD is loaded.

#2 - When setting up windows, delete the 200MB partition, and the one you created in OSX. Click "New", choose the full size, and Windows will automatically create several partitions - just go with it. Next->Next->Next finish. Once you are in Windows run "msinfo32.exe" and make sure that BIOS Mode doesn't say Legacy.

I'm completely new to this kind of overclocking. I've seen several guides, but none of them make me feel very comfortable with too much tweaking. I bought a 6700k and an OC friendly board (Gaming 6) with full intentions of OC'ing - I'm @ 4.4Ghz now using the board's built-in profile for my chip...and it's working very well. I'm wondering just how much better performance can I squeeze out of it without putting things at risk OR constantly using too much power (bad voltage settings).

It's not really that crazy/hard, it just takes a little time. Using the prebuilt motherboard settings your chip is most likely running hotter and higher voltage than necessary.
Here is a very basic idea of my process.
  • I do my overclocking stability test in windows using the Intel Extreme Tuning Utility.
  • Basically I load up the multiplier I want in the BIOS (eg 45x for 4.5ghz), and I started with a Vcore of stock (1.30 on the 6700k) and make sure to put your CPU Vcore Loadline Calibration setting to “High”.
  • If you are undervolted too far for the overclock, your computer wont even boot to windows so you know you'll have to raise the vcore 0.01 at a time. (For this chip, be weary of going over 1.4v- and you would only need to go that high if you are doing a pretty big overclock. It's always better to undervolt when testing than overvolt and fry your chip)
  • Basically once you get into windows you stress test the computer with the utility and see if it crashes or not. If it crashes then you know you need more vcore. Again every chip is different so you'll have to test out what works for yours.
  • In my case with my chip I could boot into windows with 1.30 but when it came to the stress test the computer would crash so I put it up to 1.31 and it was stable again with a max load temp of ~50C. I did put the OC to 4.6ghz but it required me to up my vcore to 1.36 and my temps were up to ~70C (wasn't worth it imo).

I fairly heavily overclocked my old 2700k, I experienced only small inconveniences in 4 years of use. My Z170x goes up to 4.7 GHz now, otherwise it would have been about as powerful as my old overclocked Z68/i2700k...
Idle at room temp(lower twenties), about 60 celsius under load. At least 10 degrees cooler than my former system. And very quiet with a Fractal Design R5 case & Noctua D15 CPU monstercooler.
Now only if I could get the TB3 ports working. And the shutdown fixed.
