6) Save and open it, reboot to apply changes.
There's very occasional times I may need to peg my GPU to maximum, for some tests. I wonder if this works with ToastyX restart64.exe to avoid the need to reboot the computer.

It does, confirmed it with this terminal command:

Dandy. Good to know. I can waste power for just a few minutes for some obscure test, without needing to reboot.

yes, thats work with restart64 or devcon

It's possible to automate this along with the Windows powerplan for games using a batch file.
This way you can save energy and play at maximum performance.
This is what I did when I used to game.
First you need to bypass the uac prompt to add the registry key. Several ways to do it.
Then find the powerplan's strings with powercfg /l.
Create a batch file:
regedit /s or reg import nvidia-max.reg
restart64.exe /q
powercfg -s 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c (high performance)
start "" /wait "game path"
powercfg -s 381b4222-f694-41f0-9685-ff5bb260df2e (balanced)
regedit /s nvidia-min.reg

you need to use 2nd restart64 (after apply nvidia-min.reg)
also you can use REGADD in batch file
+ maybe ultimate performance better then high perfomance?

Yes, forgot to add the 2nd restart64.
Sure, ultimate performance *
should* be better.
Just found an issue.
Everytime I do restart64, the monitor's audio bits/Hz setting is changed to an invalid setting.
As a result, there is no sound and VLC crashes trying to play an mkv.
I need to change it everytime.
Also noticed that when Windows boots, the cpu-z timers tool shows the RTC is slower than ACPI and QPC.
But when I run restart64 at least two times, it will be in sync with the rest.

try to repeat this test without nvidia driver (disable gpu in dev.man.)

im need more info about RTC, bro
always after 2 reboot or it can be good on startup without reboot, or maybe 1 reboot fix that?

At boot, RTC will go out of sync.
Seems that even even when I run restart64 two times it sometimes goes out of sync. It behaves erratically.
I ran restart64 like 3 or 4 times and left cpu-z timers tool running for 5h and it was good.
Windows is using TSC so I think I will just forget about this or I will go crazy trying to find out what causes it.
