i7 4700MQ stuck on 1.5 Ghz

Recommended Posts

Posted · Original PosterOP

Hello

 

Since a few months I'm a owner of a alternate 17CL58-GTX765 (which is just a rebranded Clevo W370ST).

However the last weeks I started experiencing that the CPU clocks itself at 1.5Ghz and it stays at that level(not really that helpfull when I'm gaming). Even switching from different power modes does not help to change the clock speeds.

Even running a prime 95 stresstest does not seem to alter the clock speeds. Maybe it was a driver issue, so i uninstalled all the intel drivers and reinstalled them, unfortunately the CPU stays at 1.5Ghz.

 

Does anybody might have a clue what is going?

 

Thanks in advance!!

it could be thermal throttling? IDK just an idea.

two reasons this could happen

 

A- your application does not require the cpu bandwidth

 

B- your cpu is throttling under load.

 

I would suggest running cinebench  or a cpu stress test and monitor your cpu frequency and determine if it is throttling under load

 

if it is try this application

well i ran bf4 and some other games in windowed mode with the monitoring software next to it. what i can see is that the cpu is still runnnig at 1.5 Ghz, however i am able to get a stable 60 frames per second in BF4.

even running cinebench does not seem to do that much unfortunately :(

also be sure your windows power saving features are set for performance.

thats pretty warm, and are you using cpuz to see the speed.

it is also possible cpuz is bugged. try a different \ updated version.

 

you can also use intel extreme tuning utility to monitor vitals

according to the cpu-z website 1.69 is the latest version. will try the extreme tuning utility in a moment

OK now i tried the intel processor diagnostic tool

 

at first the test fails at the frequency test

however after manually editing the settings via the intel extreme tuning utility the test seems to run fine.

Is it possible for intel speedstep to have been bugged or something(if that is possible at all)?

i just edited a the multiplier for a single core active from x34 to x33 and then the CPU kicked itself up to 3Ghz with prime running in the background

it was possibly throttling so by you reducing the core frequency it may have required less voltage and gave you some thermal headroom.

 

watch your temps close

 

give throttlestop a go

xtu will also tell you if your cpu is throttling.

 

click the blue wrench towards the bottom of the screen on the right hand side.

 

check off the cpu throttling box

while monitoring the CPU with XTU, it said that teh cpu was not throttling

 

now i installed installed throttlestop and i saw that the disable turbo checkbox was ticked, so i unticked and in a matter of milliseconds the CPU started working normal again?

still not sure how but aparrently it is working fine at the moment...

Try using Trottlestop. It's designed to combat issues like this. You can also force the CPU to run in turbo frequency all the time. Just make sure that the program will start itself with the Windows and you'll be good to go. Don't forget to monitored temps at least in the beginning just to check if the laptop is not overheating.
