Hi Intel and the vast public,
I am working towards benchmarking on Intel Hardwares, may I know is there any possible ways to change the Intel iGPU core frequency on Windows 10? Previously, I have managed to change the core frequency for iGPU on Ubuntu 16.04.
Hi Raju, thanks and yea I understand how the GPU frequency throttles according to the usage, but in Ubuntu 16.04, I can set the GPU clock frequency to a fixed value. I was hoping I can do it for Windows 10 too, maybe some Intel folks can provide tools for this use case?
There is no API or GUI capability for adjusting these settings in Windows. Most boards/systems include support in BIOS for adjust these parameters, however.
Hi Scott, thanks.
I wonder if i can do it on Ubuntu 16.04, there should be a way in Windows10. Anyways, let's see I can find anything at the BIOS.
Ok, new day; new thoughts: Have you checked to see if XTU (Intel's eXtreme Tuning Utility) offers the capabilities that you need? I tend to ignore it as I am not an overclocker, but it may offer something...
Hi David, my query has not been resolved yet. I want to thank N Scott Pearson for the tip, I have installed and tried out the Intel XTU Software, but it does not allow me to configure my Intel iGPU frequency, it only allows me to configure the corresponding voltages.
May I get some help from Intel integrated GPU team?
And also thanks N.Scott Pearson!
In Ubuntu 16.04, this are the commands that I used
echo 800 | sudo tee /sys/class/drm/card0/gt_max_freq_mhz
echo 800 | sudo tee /sys/class/drm/card0/gt_boost_freq_mhz
echo 800 | sudo tee /sys/class/drm/card0/gt_min_freq_mhz
800 has the unit of MHz
To monitor current GPU frequency
watch -n1 "cat /sys/kernel/debug/dri/0/i915_frequency_info | grep Current "
