Many user have the same problem, are you working on a patch for normal cpu idling?
Same issue here, where's an acknowledgement intel?
Does the issue persist after the Intel® HD Graphics driver has been uninstalled?
I have tried to uninstall the Intel HD Graphics driver via device manager uninstall + remove driver on this device. It results in the device becoming really laggy opening/moving windows, but the throttling problem stays.
So, it is not a driver issue if it persists after the driver has been uninstalled; is it? Does this happen all the time or when using a particular application?
Please look at the video posted on first post. It shows all what needs to be known => CPU does not clock down correctly when idling. I'm not sure why you asked me to uninstall the HD drivers though, I dont think the HD Graphics drivers are related to CPU throttling, I assume some part of the chipset driver or Intel DPTF drivers are. And like you see I am not the only one having this issue.
Those drivers (your Intel drivers) do 1. nothing (are broken, which is this thread all about!?) 2. I have the latest bios 3. it works correctly under Windows 8.1
Try to manually configure your idle CPU throttling in Window10.
Right-click "Start", click Power Options. click Change plan settings, click Change advanced power setting, click Processor power management
if you can't see "Processor power management" then unhide it with Regedit. (read a simple tutorial: Hidden power settings on your Windows 8.1 tablet or PC )
Go back to Power Options, and try following configuration:
Processor performance increase threshold = 90%
Processor performance decrease threshold = 33%
Allow throttle state = ON
Processor performance decrease policy = Rocket
Processor performance increase policy = Single
Processor performance time check interval = 50 milliseconds
Processor performance history count = 10 time check interval
Processor performance increase time = 1 time check interval
Processor performance decrease time = 20 time check interval
Press "Open Resource Monitor" in Task Manager, check the BLUE line on the CPU graph, this is the throttle level. Tweak the settings until it behave like you wanted it to be. Make the Blue line a bit higher if video had "pop"/"crackle" sound, but lower it as far as you can to reduce heat & save battery, tweak "check interval" if UI felt sluggish, ect (its up to you...)
Finally someone who tries to help. Thank you, Ive tried your settings, they didnt do anything though. But the idle lower frquency now seems to be a bit lower, now it jumps between 1.05GHz and 1.45GHz.
I alsoe tried to disable Intel SpeedStep in bios and that results in the CPU going forever in its lowest power state of 500MHz. So it is totally a driver issue, or these settings arent properly optimised for the Atom processor under Windows 10, whatever reason why. It seems the load to processor state isnt translated correctly.
What I find weird is though the kind of jumpes it takes, all between 1.05 and 1,7 even if load is 3%. I know there was some kind of c-state bug with some processors in Windows 8, which this could also be somehow related to.
Any suggestions on optimizing those settings? The bad thing is, there are too many... I had to enable at least 50 settins in the registry of the link you gave me, and I dont know what of those I have to change. For example there are options next to "Processor performance increase threshold" called "Processor performance increase threshold for processor performance class 1" too.
I also went to look under "Press "Open Resource Monitor" in Task Manager, check the BLUE line on the CPU graph, this is the throttle level. " and noticed the blue line is always at or above 100%... is this normal!? https://dl.dropboxusercontent.com/u/14937594/IMG_20151009_001604.jpg
Also why is it at 103%? when it's 3% load? After some random time it is also locked at always 125%... I dont think this is normal, and totally a driver bug I guess?
Here are more people btw having the same issue since beta:
I don't know what else I could help, the settings is working fine for me. I have Window 10 Home with Atom Z3735G SoC tablet.
Maybe you could tweak the C-state setting that you mentioned, in BIOS. I remember my lowest C-state setting for my Atom is "C7" (this seem to be the default value). Just don't touch setting with name like "GPIO" or "USB" because its very bad. Usually tablet don't have BIOS reset jumper, so if it couldn't boot; then nothing can be done except claim for warranty & replace motherboard ( ).
The "Processor performance class 1" settings don't do anything for my PC, Laptop, or Atom tablet, so just ignore it.
The "125%" is because your CPU is "boosting". This mean your Window 10 asked for more performance & the processor temperature is low enough to allow it, so it increases your processor's Ghz by 25% because it can. (but I disabled it because my Atom tablet don't have any heatsink and it just cause it to freeze up. I set "Processor boost policy" to 0%).
The settings that contain name like "concurrency" and "parking", control how many core is sleeping. I don't know any good value for it,
My dell has started throttling, but damn, the HEAT IS INSANE. since updating to 10 it gets so hot the screen starts going CRAZY. heat on 8.1 is fine, but 10 is unusable. gets to high 80's, but does show it'll drop below 1.3ghz. idkwtf. it's killing itself and destroying my hardware.
