You don't solve it, you deal with it. Clock speed indicates how many tasks it can do in a second. Having low number meaning it doesn't do many tasks. Do you need it to do?
Think of yourself for a second. Do you run fast to get somewhere all the time? You don't. Most of the time you walk because if the cpu runs at its max all the time it will propably having issue.

Is the cpu under load? If not it throttles down automatically to save power. The only time you are going to see it at its max clock speed is when its doing something that requires it, that does not include browsing the web and checking emails.

100% load will see it reach its advertised frequency, if you are idle with less demanding workloads open, then the CPU will dial down to be suited for the task at hand, this can be changed in the BIOS, but it a way of lowering power consumption, by only running as fast as it needs to be for the current usage.

Its like having a car, you want to go somewhere, and your not in a rush, your drive at a moderate speed, say 30mph, but the car is obviously capable of hitting higher speeds, but because of your demands the speed is low.

If you want the CPU to be permanently running top speed 24/7 then you can change a Cstate or power conservation setting in the BIOS that will enable the CPU to run at 2.44Ghz permanently. Obviously this is not needed, and its probably best for you to use Cstates as it will help out in the electrical bill!

But even when I am playing a game it still only works at 0.77ghz and my screen lags for any action i do in the game. Is it still normal for it to work at 0.77ghz?

Are you plugged in? What are your temps? Do a stress test and check.

My temps are 60-70 degree Celsius and this test was done when I didn't on the air conditioner in my room.

60-70 defree is totally fine. The problem is the performace.. Lagging could be also the gpu? Which gpu and whic game you trying to play

It is nvidia geforce gt750m and I tried a lot of games like league of legends, portal 2, and even maplestory

 

[Ian218]

What ever games, or programs I on, my processor only works on the speed of 0.77 ghz

 

[k1114]

Check your power settings and see if max processor state is 100%. What did you use to test? If you are at that speed and 60-70c, you would be overheating at full speed. Did you use software that shows max temps? Where are you looking at cpu speed?

 

[Ian218]

Im looking at my cpu speed at task manager and yes it shows max temps to 100++ and yes my max processor state is 100%. I also checked at OCCT to stress test and it was still the same with other apps

 

[k1114]

Ok that's a big issue as task manager never shows the right speed. Use cpuz. Max temps getting 100+ tells me I was correct that you are overheating. It's throttling due to heat and still getting too hot idling at 60-70. Only way that would be happening is a heat sink mounting issue. If it's under warranty you should send it in. Some laptops don't mount it very well and it gets loose.

I meant that the graph shows it will show if the laptop goes over 100 Celsius and it is 50-70 now. It shows my core speed as 798.10mhz and Bus speed is 99.76 Mhz.

 

[k1114]

You want something that keeps track of max, what max on the graph is irrelevant. But even at 100% usage at the low speed, you shouldn't be hitting 70c. If speed goes up, it should be overheating.

Then what can I do to reduce the temp and what should I do to stop my computer from lagging while using it? It hardly lags when I watch videos but it lags a lot when I play games, even games like maple story that doesn't even need graphic card to play.

 

[Ian218]

Could it be a fps lag? If it is how could I fix it?

 

[k1114]

Heat sink issue as I stated before. The low speeds won't affect videos since they are so low usage. Even an old low end game like maplestory needs more cycles so would expect it to lag more.

So what should I do in order to get rid of this lag..? Is there nothing I can do about this?

 

[k1114]

No warranty? Open it up and see what you can do.

 

[Ian218]

yup warranty finished.. then do I just clean the fan?

 

[k1114]

Make sure the heatsink didn't come loose.

 

[Ian218]

Yup it isn't loose. Thanks for helping me everyday.

 

[k1114]

Did you try to reapply thermal paste?
