So your idea that IXTU decides " I don't have to do anything", is not how it seems to work. A wake from Sleep or Hibernate situation does not cause our settings to be applied, nor does a cold start after a shutdown. My point here is IXTU will only apply a change in settings when we manually tell it to do so.
I ran it once to apply my settings, and then manually exited IXTU. At no time after the restart of the PC, or before I shut it down, did I run IXTU. I can shutdown the PC, but not remove power (PSU not turned off), and the IXTU settings are not lost. On my desktop PC (Z170 board, Skylake processor, IXTU version 6.0.2.8) after applying changes via IXTU, and exiting IXTU manually (which means IXTU does NOT auto-start after any of the following situations), and restarting the PC (not a shutdown), the changes I made in IXTU are not lost. I'm wondering if the case where you lose your voltage settings is caused by the PC coming out of Hibernation, rather than just Sleep. Until after a few days, the default matches my active value again". randomly, after a sleep cycle.", and then later you said, ". You said the loss of your voltage settings occurs ". I have some questions about your situation:
You might want to include the version of IXTU you are using in your post, as I'm sure Intel Support will ask you about that. I'm not sure how to solve the wake from Sleep issue it seems IXTU is having with your laptop.
I have to constantly battle this by changing the voltage offset back and forth:ĭefault: -92.77 mV, Active: -93.75 mV, voltage is lowered by ~0.09 V. Until after a few days, the default matches my active value again:ĭefault: -92.77 mV, Active: -92.77 mV, voltage goes back to normal. It works well at first, and I'm getting a 20% performance boost when the CPU is TDP limited.ĭefault: 0.00 mV, Active: -93.75 mV, voltage is lowered by ~0.09 V.īut then, randomly, after a sleep cycle (close & open the lid), the default voltage is changed to match the active one and XTU interprets this as "I don't have to do anything".ĭefault: -93.75 mV, Active: -93.75 mV ( Screenshot), voltage goes back to normal.Īs there is no way to change the default manually, I have to change the voltage by just a tiny bit, and it works again.ĭefault: -93.75 mV, Active: -92.77 mV, voltage is lowered by ~0.09 V. I'm having a really annoying problem with Intel XTU when trying to undervolt the CPU.
