CPU Throttling to 1GHz - in Windows 10 only

Hello everyone!

Recently, my laptop has been experiencing massive slowdown in Windows 10. Specs are that of a UX32VD-DB71 (RAM changed to 2GB onboard + 8GB Corsair Vengeance 1600, storage changed to Samsung 840 Series 250GB). I've noticed that my CPU is almost constantly throttled at 1GHz now (when it would normally be Turbo'd to 2.8GHz most of the time), and I have no idea why. My first guess at solving the problem was to reinstall the Intel Chipset drivers, but that didn't change the behavior in any noticeable fashion. The CPU would still randomly, and very rarely, boost to 2.8GHz for short amounts of time. I then tried to do a clean install of Windows 10. It seems this has unfortunately also been ineffective. At this point, I'm stumped for options. I would love any suggestions, and I can provide any more screenshots needed to diagnose the issue.

Here are a few that I have for now.
Using the Turbo Boost Monitor tool (since my processor is a 3rd gen Intel proc), I can see that the speed setting is on "Energy Saver" although I can't seem to change it from that particular app. Important to note that my laptop is on High Performance, and plugged in.


Starting Task Manager. Normal behavior would have CPU usage spike to near 100%, then drop down to low usage once Task Manager finishes starting up. Here, it jumps to 41% (the maximum usage when throttled at 1GHz).

All four logical cores are at 41% usage, the maximum under load.

Getting the CPU clock speed from Terminal in Linux. Bonus askubuntu answer in the background since I'm a scrub at Linux.

Again, any and all suggestions are appreciated, since I'm at a dead end after doing a clean install.

Are you running on battery? If so it just sounds like battery related options are slowing it down.

If not, you might need to do a reformat using the newest media tool and the manufacturer Windows 10 drivers. There was one older HP laptop that had a similar issue, and one reformat and a dozen restarts later it fixed itself.

"Important to note that my laptop is on High Performance, and plugged in."

I have reinstalled all the up to date manufacturer drivers.

How would I deselect best answer? I'm a dummy and clicked the green button in the email that said "Select as best answer"

But...I literally did a clean install a few hours ago.

Just because you did a clean install doesn't mean it went through properly. Download the media creation tool again and make a new installer, making sure to add all the base drivers when you can load them rather than afterwards

So, I went ahead and installed ASUS' provided Windows 8.1 custom power profiles (Power4Gear) and switching to high performance seems to temporarily unthrottle the CPU. It throttles permanently back to 1GHz after the system determines there's a low enough load on the CPU, however, so I made a batch file that literally just cycles the power profile between balanced and P4G High Performance. I just run this whenever I next need my CPU back to full turbo boost level. Not exactly a good fix, but it's the best I've got at this point.

Here's the batch file in question just in case it would help describe the situation better.

So in other words the manufacturer does not support Windows 10 on your system? Of course that will cause problems.

I have a UX32VD too, and I am experiencing exactly the same issue (I have added the same SSD, and 8 GB but not the same one that you have).

It seems that i can keep it on high performance, until it actually has to perform, and then it drops to 1 ghz. It might be a temperature thing, but I cannot be sure.

If you have solved the problem, I would love for you to post it here :)

I too am having this problem. Only occurred after upgrading to windows 10. But I have my own custom built pc that I built.
Spec:
Fx 8350
AsRock 970 Extreme3 mobo
16gb ram at 1600mhz
Windows 10 64 bit home
Upgraded from windows 7 64 bit home.
Using H60 Water cooler.

I know the throttling is standard safety when overheating. But my idle temps are 18 degrees and under full load at 4.4ghz only hit 43 degrees. So heat is not the problem. Also, the dropping to 1.3ghz at 0.8 volts happens more frequently idling (1/every 2 min) compared to under load (1/every 40 min). It was a fresh install upgrade, on an SSD. Again this did not occur on windows 7. I of course updated my drivers via AsRock site. Any ideas what could be causing this? Anyone else having this problem?
Note: when the drop occurs, when idling it lasts usually 6-8 seconds, when it occurs under load, it lasts about 3 seconds. Also when it does do this, my temps drop dramatically when idling it will drop from 18 degrees to 8 degrees, when under load it drops from 43 to 35. Any fixes out there?

Make your own thread with the information necessary (specs, overclocking software, confirmation of the drivers and BIOS revisions being up to date, etc). Your situation is not the same as OP's so it'll be best to ask in your own thread

I also have a UX32VD with the extra 8 gig and ssd. Its also throttling to .96Ghz. It has been running like a hog ever since I did a rebuild of windows 10. I never saw it rise above that in my latest rebuild of windows 10 until I set my performance to max and then set the minimum processor state to 100%. It was the first time I've seen it climb above .96 and act like my old machine again.

I'm not sure if this solves the issue but I'd like to be notified if anyone else comes up wit h anything.

As for both of you with the UX32VDs. Have you encountered any issues with yours? My build in SSD died a couple years ago which I fried off with a soldering iron. It has generally been an excellent machine up until recently when my keyboard started acting up and it slowed down like crazy. The S key now appears to be dead and I've ordered a replacement keyboard. Lately my wifi hasn't been recognizing any wifi and I'm wondering if perhaps its related to the latest build of windows 10. I'd appreciate any feedback on what you guys have seen.

Ok, one issue I've noted is that the drivers for the intel thermal platform installed with windows 10 were from 2009.

I went to the asus site, selected windows 8 drivers and dnloaded the ones there under other. Big change after that. So far the system is running at 2.5-2.6 ghz, it is responsive again and feels like the old powerhouse it used to be

Looks like you found the solution, well done.

Where in windows is the "performance" and "minimum cpu state" are you talking about the advanced power settings? In regards to your WiFi. Perhaps the same problem with the drivers. Try installing the windows 8 drivers and make sure you change the windows update settings to NOT automatically install hardware driver updates. The last 4 months of windows updates for myself and my dad's pc has updated drivers to various hardware and broke that piece, such as they updated my Lan wired hardware and broke it, updated my dad's Logitech mouse hardware and broke it also updated his display drivers and his monitor no longer worked until I uninstalled the drivers and used the manufacturers drivers to get it working again.
However as for my custom built pc having the 1.3ghz drop, I never considered reinstallin the windows 7 drivers for my chipset, also I've confirmed the drop only occurs when idling/basic Web searching and such, when gaming the cpu does not drop. But the whole thing of windows10 messing with my default clock speed causing it to run hotter. Just changed in bios to default to what windows 7 default was, which was 4.4ghz at 1.45 volts. That is the proper settings in which the cpu runs the coolest at 18-20 degrees idle and 36-43 under load. Any less clock speed and volt my cpu would run hotter, idle at 35-37 and 55-58 under load. The only other perfect setting was 3.5 ghz at 1.30 volts, that idled at 8-10 and 32-36 under load. Keep in mind my pc is custom built with the fx-8350. So I will try windows 7 or 8 chipset drivers and see if the drop stops. Will post results when I can.

I just use the pc meter gadget and core temp gadget. They both match when I have them running simultaneously which I did just for testing when I was figuring out the "perfect" clock speed and voltage that ran at the lowest Temps since windows 10 defaulted to something other than what windows 7 did. Windows 10 defaulted to 4.2ghz at 1.325 volts but the Temps idled at 35-38 and 55-58 under load. Windows 7 defaulted to 4.4ghz at 1.45 volts and idled at 18-21 and 35-43 under load. I just manually set the 4.4ghz at 1.45 volts in bios for Windows 10 then ran stability test to confirm it was stable and it was.
