ASUS Laptop clockspeed is really low

[leon1912]

Hello,

I have a ASUS Laptop with an Intel Core i3-6100U inside.

When I don't charge the Laptop the clockspeed is sometimes at around 500 MHz.

How can I turn it off?

I know that the U models of Intel CPUs are energy saving models.

Sorry for my bad English. :)

 

Best regards from Germany

I attached a screenshot that you can see it and don't know what I mean.

That's normal when you're in idle and on battery - if your CPU runs at full speed, you'd get 1 hour of battery or lower

Change your power plan profile to high performance.

Go to advanced settings and set Processor power management to max.

 

Note: you will drain the battery FAST

It should not be running that low, unless it only sometimes goes to 500mhz. If its stuck on 500mhz, try updating your BIOS. Download the bios update from their website, extract the contents to a freshly fat32 formatted USB drive, and then open the easyflash utiliy in the BIOS. Point it to the bios update file you downloaded and you should be good to go.

 

If it still doesn't fix it, try downloading chipset and power management related drivers from the same page you got the BIOS update from.

OP, try updating your BIOS. Download the bios update from their website, extract the contents to a freshly fat32 formatted USB drive, and then open the easyflash utiliy in the BIOS. Point it to the bios update file you downloaded and you should be good to go.

That's the normal idle clockspeed for his CPU on battery.

^^ It's the normal underclocking CPUs do when idle, just more dramatic because it's a mobile chip going for the lowest power consumption possible. Even my 4.5Ghz OCed i7 5820K in my desktop drops to 1-1.1Ghz when not under load, hops right back up to proper clocks when it has something to do. You've only got issues if it doesn't hop back up. Keep in mind some mobile CPUs have different boost clocks for battery vs plugged in though, due to the limitations of batteries.

Thanks for all answers.

My laptop has done a BIOS update automatically about a month ago.

Seems legit.

 

The multiplier on that is 4-23 with no turbo. So it is definitely within normal frequency range.

Its just the power profile/battery holding the clocks back.

I tried to play a game with running on battery,

Even there the clock speed is sometimes really low.

Then the game lag and when the clockspeed is "normal" everything works fine.

Its just the power profile holding the clocks back to preserve battery.

 

 

Most likely - this is usually commonplace on budget laptops since they come with tiny 20-35Wh batteries

That's also normal - your battery is physically not capable of powering the CPU to its maximum performance state. That's why you need an adapter if you want to do anything intensive

Well:

Laptops usually need the AC adaptor hooked up before they'll allow the CPU a full power target, on battery they usually run a bit slower. If you want the best performance from a laptop, plug them in.

I didnt think that I would get so many helpful answers so fast.

Have a great evening and already a nice weekend.

If you absolutely have to play games while mobile, suggest using high voltage power bank capable of charging laptops.

I've not done this myself but I cant see this will buy you much juice at full clocks.

[leon1912]

I don't want to play games when I am on the way.

Try running ThrottleStop and disable BD PROCHOT. 

 

 

Some of the throttling schemes cooked up by Asus for their laptops are excessive and result in miserable performance when running on battery power.  Even a 10 year old laptop from the bargain bin will outperform your Core i3 if it is stuck at 500 MHz.
