Processor Not Performing Up To Supposedly Standards?

[bornerwave]

Hi everyone, i have a laptop which i bought during the march IT fair. It's a Lenovo Z400(no touch). It has a Intel-3632QM processor. Recently, i am starting to have this problem of my processor not turbo boosting even on high performance(able to set on my laptop). It just stays at the base clock speed of 2.2GHz and does not turbo boost a single bit. It was not like this last time when i set my laptop to run on high performance. It used to run at 2.8-2.9GHz at high performance consistently... Is there something wrong with my processor? Is it downclocking itself to protect itself from overheating or something? Should i check with lenovo service centre on this? Please advice thanks

PS: i run on high performance for gaming such as Call Of Duty: Black Ops 2. Or when doing work which requires a lot of processing such as doing photoshop stuff.

Here is a picture

2 questions:
what is your laptop power settings?
are u running of mains or battery?

at more power efficient settings and on battery the laptop cpu does not run at max speed

 

[sglords]

use CPU-Z
speedfan only show what cpu u using

Windows 8 task manager would also show the actual speed of the processor...

i am running off the main power. everything is on the max settings on the power options.

the task manager showed 2.18 GHz constantly. You can also look at the top right hand corner of my picture i posted earlier. That is the CPU monitor by Intel to monitor the clock speed of the processor.

CPU-Z showed the same results at that period of time as well

I think Turbo also takes into consideration the thermals.

Turbo or no turbo you won't feel the difference...

Stop nitpicking

i do experience occasional graphical spikes in games due to the drop in clock speed of the processor. I am quite sure it is not about the GPU so yea. Not nitpicking...

yea i think so too. Is it because of the incompetence of the laptop's cooling system or what? the temperature of it never exceeds 90 degrees, it is built to withstand 105 degrees o.o

So you have logs of the precise timing that when the processor's clocks is throttled that matches with the timing when you have spikes in-game?

Think from Intel's perspective. Would they want to run max turbo when your CPU > 80 degs? They would want to throttle it down once you reach that sort of temps. Lesser variation of temps means lesser strain on chip = lesser chance of them having to replace CPUs

Your best bet (if it's a heat issue) is to open the laptop up and clean the heatsink + replace the thermal paste inside

all right, thanks for the advice, i will report this to lenovo to change it
