Things You Never Thought You Needed to Know – How to Break 5G on Z270GT6 Chapter

Class is back in session!

For all you techies who are always on top of the tech news, you will know that BIOSTAR recently released wonderful news of Korean gamers having broken the 7G barrier using liquid nitrogen overclocking on the BIOSTAR RACING Z270GT6 motherboard. This certainly is a huge milestone for all you overclockers out there! The BIOSTAR RACING Z270GT6 instantly became a huge hit amongst overclockers and is now highly recommended by many veterans in the field!

Hence, we decided to check out just how well the Z270GT6 runs! Does it really live up to its reputation? Or is it merely an urban legend?


Model RACING Z270GT6
CPU i7 7700k
Graphics BIOSTAR GTX 1060
Memory DDR4 2400 8G X2
Radiator Assassin
Power Supply GP600P
SSD BIOSTAR G300 240GB (given as a bundle with the Z270GT6 Motherboard)


Why Z270GT6?

Given the availability of today’s technology, the natural choice is to go for the latest 7 series i7 7700k CPU and a CPU that is able to be overclocked to a relatively high frequency with a stable full load as well as a Z270 motherboard. Nonetheless, many reviewers have merely shown the motherboard overclocking test, and none has yet to perform a full stability test.

We overclock in pursuit of higher frequencies with high stability that is able to withstand full load operations. In order to achieve such an effect, it is without a doubt that we need to have a suitable CPU. However, we often overlook the motherboard material and design. In this aspect, the BIOSTAR RACING Z270GT6 is definitely well-deserving of its rave and praises.



The Overclocking Process

With the platform set up, let us look at the following specific overclocking process:

1) Reboot your device and enter the BIOS by pressing Del before the startup screen.


2) Entering into the main menu interface, adjust the Core Ratios Mode option to All Core.

Some overclockers decrease the nuclear in pursuit of higher frequencies, however, that is not required in most cases.


3) Our objective is to run 5.1G. Now, for a quick revision, the FSB X frequency needs to be equal to the main frequency, and in the main menu interface, the CPU Base Clock is FSB. However, since the advent of the Kaby-Lake CPU, the frequency is generally locked at 100 by default.

Core Max OC Ratio is the CPU multiplier, and since we want to go over 5.1G, that multiplier should be set at 51,100 x 51 = 5100MHz (or 5.1G).

In order to optimise the CPU’s performance, we will need to adjust the CPU ring frequency to match the CPU frequency formula. Nonetheless, for increased stability, we will only be setting the Ring frequency to 4.5G. Enter 45 for the Ring Max OC Ratio.

For memory frequency, first set the memory profile to custom profile. In this demonstration, we will only be using 3200 frequency memory, since we don’t want to risk overheating in the internal components to affect the stability. Hence, we will be setting the memory ratio to 3200.

Now, we will proceed to enter the voltage configuration menu to set some of the power supply parameters.



4) Firstly, we will set the CPU Load-Linne Calibration to level 6 and select the overcurret protection option under Over Current. However, CPU Switching Frequence and VGT Switching Frequence CPU and CPU core is the power supply PWM frequency, where the frequency is usually set the highest, CPU PWM frequency is set at 500KHz, the nuclear PWM frequency is set to 450KHz.

Afterwhich, we will set the CPU voltage. Set the CPU power supply voltage mode CPU Vcore Over Voltage option to Override.

For the option of CPU Vcore Adjust Voltage for the CPU voltage option, one will usually have to slowly understand the inner workings of the motherboard to know. However, we have managed to understand the inner workings for you. Set this to 1.36V.

Next, the DRAM Voltage for the memory voltage. Since we are going for 3200, DDR4 1.5V has generally no problems, the voltage over 3230 should not be a problem either.

Now we’re down to the CPU internal memory controller, or the IMC voltage regulation. The voltage is generally the optimal CPU voltage, not too high, nor too low, otherwise it might affect the stability.

Next, just hit Esc to return to the main menu, then enter the CPU Power Management menu.



5) Follow the values entered in the image above to ensure power protection settings as it determines the amount of power consumption before CPU perfromance drops and this is usually set to the maximum number.

Finally, hit F10 and press Y to save and we will enter the the system for AIDA pager.



In Closing

Thanks to the excellent power supply of the BIOSTAR RACING Z270GT6 Motherboard, we were able to overclock to 5.1G with a high standard of stability.

We hope that the BIOSTAR Blog was again, able to bring to our readers valuable information and tips on how to perform certain tasks, and in this case, how to break 5G on the BIOSTAR RACING Z270GT6 Motherboard. We trust that with this information, you will be able break 5G with 7700K – so long as you’ve got the proper memory!

See you guys next time in out next lesson time! Peace out!

  1. I’ve tried to follow these instruction step by step, but i cant find most of volt setting on my bios, its seem you’ve got different version than mine, so what version did u use on this tutorial? Can u upload “exported version” of this setting ? so i can simply import it to my bios, thank you 🙂
