CPU or GPU issue ? - Page 3

post #21 of 44
There are several reasons why a gpu will throttle. The main ones that apply here would be temp limit or power limit. Gpu-z will tell you which one it is.

Typically now throttling is done in stages. It's not just gonna fall flat on its face. It's going to fall to predetermined points in stages in order to get temps under control and also to keep performance up.

If you find out it is a issue with heat and your brave, I would open it up and put some new thermalpaste on the chips.
Budget gaming laptops are not a good. Manufactures use low quality parts (not just the hardware) in order to meet price/profit.
I can guarantee the paste on the chip right now is crap.
If its your main gaming outlet then I would sell it for a desktop.

Thats thermal throttling already happening.

The Core i7-4500U typically throttles based on power consumption. The U series are low watt CPUs and have a TDP rating of 15 Watts. These CPUs are designed to adjust their performance as you use them. They can run at full speed for a short period of time but long term, they will throttle back so they do not exceed the 15 Watt limit. These CPUs also use TDP Levels. If your device manufacturer decided to use the low TDP level that these CPUs are capable of, the power limit can drop in half and the multiplier can get locked to 8 so your CPU will be stuck running at only 800 MHz. Manufacturers are very quiet and deceptive about low TDP Level. Depending on what locks have been set by the bios, about all you can do is reduce power consumption to try and keep your CPU away from going into low TDP mode.

You mentioned that you are using ThrottleStop so make sure you are using the latest version.

ThrottleStop 8.00 b7

The best way to improve performance is to reduce power consumption. You can use this version to reduce your CPU voltage. Less power consumption allows the CPU to run at its full rated speed longer. Also make sure BD PROCHOT is not checked. Some laptops use this signal path to the CPU to throttle the CPU based on an external temperature sensor on the motherboard. Skin temperature sensors are being used in the latest devices to trigger throttling.

You should also be using the Limit Reasons program by Dufus. It will give you a better idea of what limit is triggering throttling. The latest version of ThrottleStop also writes this information to the log file so you will have a good record of what your CPU is doing.

Bro how can i know using gpu z ? What should i understand when i am monitoring the power limit ? I should see some power drops?

Hello ! thanks for your concern !

I had noticed that when ever im seeing the fps drop , My cpu clocks are always stable from the first of the game till the very end , about 3000 mhz , but my gpu core clock is the one dropping itself from 1.1k to 600-400 . My temp limit by default is 67 degrees , when im seeing that fps drop , my cpu temps are very normal , 79-82 , but my gpu is throttling itself , its kind of wierd you know ? Cpu temps are very normal and my gpu is throttling ..

Hello and Thanks for the reply and your concern !

I am monitoring everything while im gaming , for the cpu and gpu . Im super sure that im not cpu throttling , since my cpu clocks are always stable at almost 3k hz , and my cpu power never exceeded 12 watts , its always at a stable 10-12 watts.

And im not using throttle stop till now , im just getting to understand it before i can use it and tweak my settings . But, im very sure that im not cpu throttling . Its my gpu throttling my gaming performance.

What should i do to get my gpu clocks stable ? This is what im looking for , can i help doing it using throttle stop ?

Can you tell me how to make sure that my cpu is not throttling itself and subsequently it will not force the gpu to throttle ? The gpu will self throttle itself for anonymous reason , but it must be the temp limit ?

Yes it's the temp limit. You're thermal throttling. Did you get clean it as originally suggested? Spaces inside laptops are tight, esp between the fins of any heatsink. It doesn't take much for dust to start collecting.

I cant fix it in any means of software ? Cant i force my gpu clocks to run stable at all times ?
