i7-7500U drops to 0.38 GHz at random times when a program is active

Hello

I bought this computer on january and since then, it´s having problems with frame drops. at first, i though it was the graphic tarjet that is not a bad one but is not considered great (its a radeon R7) but then i began to monitor what happened in the performance bar and i saw that the when the frames drops, the frecuency of the processors also drops at 0.38 GHz and its very annoying it's not a temperature problem i checked and on idle, the pc is normally in 35-40 °C and when it has heavy programms running, it goes to 50-60 °C.

So here i am, asking for help

This means that something else is causing the processor to be throttled. In my experience, there are two causes; either the BIOS, typically via its ACPI tables, is specifying criteria for when this throttling should occur or some external entity is asserting the PROCHOT signal to the processor. You need to be talking to your board manufacturer regarding what they have done that could cause this.

Translation: This type of issue is usually caused by the motherboard (and usually its BIOS). Contact the manufacturer of this motherboard (or system if its a laptop) and ask them to help you resolve this issue. Tell them that something on the motherboard (or in its BIOS) is causing processor throttling.

Hi, you were right, it was the BIOS that was causing problems, updated the BIOS and problem solved.

Thank you very much

It was working fine at first but then it begin to decrease it's performance until it got the same as it was before. What would you advise to change in the BIOS?

Unfortunately, without the system sitting in front of me, I have no idea how they have exposed their BIOS configuration. Look for a scene with parameters related to power and take a picture of the settings scene and post it here. Alternatively, you could call the board/system vendor and ask them where it is configured.

Could be. There should be some parameters specifying limits.

This is on the chassis. I am talking about parameters within the BIOS. Power up the system and use whatever key is necessary (F2, ESC, etc.) to enter BIOS Setup. Then look for parameters related to power. If this isn't something that you can handle yourself, call the manufacturer and ask for their help.
