Undervolting core i7 8665u on Dell possible with Intel XTU but not with Throttlestop

[hitsov]

Hey @unclewebb, I really love Throttlestop, but I have a small problem with it. Upon normal restart of windows Throttlestop sometimes thinks its abnormal restart and resets the voltages and I need to set the voltages manually. If I manually close all programs before restart that usually helps. Is it possible to restore voltages with the click of a button or something similar?

@hitsov - The last screenshot you posted shows this.

You are telling ThrottleStop not to save your voltages until after you exit ThrottleStop. If you have done some testing and your voltages are stable, switch to the last option.

"OK - Save voltages immediately" should solve your problem.

Thank you @unclewebb! TS is the best thing after sliced bread!

The latest version of ThrottleStop makes it easy to see when CPU voltage control is locked.
If the FIVR monitoring table is reporting +0.0000 from top to bottom in the Offset column, the voltages are locked.

Thank you UncleWebb.

I defaulted my BIOS and upgraded to the Beta and now near enough all of my FIVR view is greyed out. The only plus side I now have is that HWmonitor is registering 4.8Ghz boost clocks once more. Is there any light at the end of the tunnel or should I now admit defeat...?

Go to BIOS and reset to factory defaults (2nd option). That did the trick for me, otherwise the undervolt was locked.

Hi Hitsov, could you confirm what BIOS version you are running?

Hi,

I updated my BIOS a recently, so I think its the latest version for 7400. Try another reset option in BIOS, if it doesnt work, try the oldest BIOS you could find. Plundervolt was discovered in June, so if you try something around that date or earlier it might work.

Intel released their first Plundervolt patch December 2019. It has been around for a year now. It took some manufacturers a while before they started adding this fix to their BIOS.
