Hello you for posting on the Intel® communities. Troubleshooting I've tried: I've disabled the Windows features that the help file states are incompatible with XTU with no change to this inconsistency (Core Isolation Memory Integrity (HVCI)- Windows says "the page does you are trying to access has no supported features and is not available" Hyper-V is disabled Virtual Machine System is disabled). Note that the functionality will be restored or removed without any changes being made to my system or BIOS. However, more often than not, XTU will not allow me to apply the selected undervolt, or it will not allow me to make any changes to the Core Voltage Offset slider despite this being colored as active in the window. The undervolt has, on some occasions, been maintained after shutdown/restart. For reasons I can't explain, I have, sometimes, been able to apply the undervolt and the temperature drop and performance improvement is noticeable. The XPG Xenia laptop listed in my sig is one of these (LAPQC71A), and I have it undervolted using this method.I have a 12700KF processor that I am trying to undervolt using XTU.
Intel did a similar thing when they included the ability to undervolt the Intel CPU (right from the UEFI setup) on their white-box laptop, also known as the Intel NUC 9 Extreme laptop kit (LAPQC71*). That tells you the system is not stable and you need to change the settings.Ī large voltage increase could cause permanent harm, but I doubt this program would permit that, since it is a utility written and distributed by Intel for use on their own products. Identifying and mitigating the instability is part of the process, and indeed the goal of stress testing is to get the system to crash or lock up, if it is possible.
The worst you are likely to see with a program like this is instability, which is temporary (as soon as the settings go back to the stock settings, the instability will be gone also. You can make them persistent if you wish, but they can just as easily be backed out and things will return to the default settings. The changes one can make with the program are not permanent.
