We’re overclocking the Intel UHD Graphics 750 up to 1750 MHz in 5 minutes or less using the ASUS ROG Maximus XIII Hero motherboard.

I’ll speed run you through the BIOS settings and provide some notes and tips along the way. Please note that this is for entertainment purposes only and most certainly not the whole picture. Please don’t outright copy these settings and apply to your system. If you want to learn how to overclock this system, please check out the longer SkatterBencher article.

Alright, let’s do this.

UHD Graphics 750 Overclock Settings

When you’re entered the BIOS, go to the Extreme Tweaker menu.

Set AI Overclock Tuner to XMP I. This will increase the system memory frequency to its XMP rated speed. In our case that’s DDR4-4266. Increasing the system memory can have a significant impact on the performance of the integrated graphics. For example, in our tests we saw an improvement of up to 30% in CS:GO

Set Max. CPU Graphics Ratio to 35. This will increase the maximum boost frequency of the graphics cores to 1.75GHz.

The way to calculate the frequency is by first halving the base clock frequency, then multiplying with the graphics ratio. In our case, the base clock frequency is 100MHz and the graphics ratio is set to 35. So, the graphics frequency will be 100 MHz divided by 2 multiplier by 35 resulting in 1750 MHz.

Note that this doesn’t fix the graphics ratio to a specific value. When idle, the graphics frequency will enter a low power mode and reduce both its operating frequency and voltage.

Set CPU Graphics Voltage to Offset Mode. This will ensure we are still using an adaptive voltage, meaning the voltage will increase and decrease according to its frequency and workload following the V/f Curve of the graphics cores. Using an offset will affect all points on the V/f curve.

Set Offset Mode Sign to +

Set CPU Graphics Voltage Offset to 0.350

In adaptive mode, the CPU will interpolate the required voltage for a given frequency between the base frequency and our set maximum frequency. If our base frequency is 350 MHz at 0.4V and our maximum boost frequency is 1300 MHz at 1.05V, then the interpolated voltage for 1000 MHz will be somewhere between 0.4V and 1.05V. If the V/f curve is linear, that would be 0.86V

In our case, since we increase the maximum boost frequency and the offset, the base frequency is now 350 MHz at 0.75V and the maximum boost frequency is 1750 MHz at 1.4V. The interpolated voltage for 1000 MHz will be somewhere between 0.75V and 1.4V. If the V/f curve is linear, that would be 1.21V.

Then save and exit the BIOS.

UHD Graphics 750 Overclock Performance Result

To make sure everything is working as intended we re-run some benchmarks and check the performance increase compared to the default settings. Higher is better; and all are higher. Compared to stock, the GPU frequency increased by 35% from 1300 MHz to 1750 MHz and the memory increased by 100% from DDR4-2133 to DDR4-4266. The benchmark performance increase ranges from +31% in 3DMark Night Raid to +60% in CS:GO.

When running Furmark GPU Stress Test, the average GPU clock is 1750 MHz with 1.398 volts and an average memory clock of 2133 MHz. The average GPU temperature is 36 degrees Celsius, and the average GPU power is 25.19 watts.

And that’s it, thanks for reading and see you next time!
