I have been using XTU for 2 years but i had to set windows factory reset. And after that I'm not able to undervolt my laptop CPU.
Unfortunately I don't remember which version I have been using. I tried
older client versions as XTU 188.8.131.52 without succes.
What happens is that when i just change number of any parameter without applying it the XTU crashes.
My specs are:
Lenovo Legion y740 15-inch
Intel Core i7-8750H 2.20Ghz
NVIDIA GeForce RTX 2070 with Max-Q Design
Win 10 Home version 10.0.19044
Bios version AVCN21WW(1.11)
Thank you for any advice
Hradaa, Thank you for posting in the Intel® Communities Support.
In reference to this scenario, as you can confirm in the link below, the Intel® Core™ i7-8750H is not listed under the supported processors for the Intel® XTU tool so, it is expected to notice this kind of behavior on a platform that it is not supported.
So, we recommend in this case to either use the Intel® XTU strictly as a monitor tool for your unit, or to uninstall it:
Since altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components, and may reduce system stability we advise to use the equipment at stock configurations with the default BIOS settings. Product warranties may not apply if the processor is operated beyond its specifications. Check with the manufacturers of system and components for additional details on this matter:
Any questions, please let me know.
