Hey guys,
I recently got a Sony Vaio laptop (the model is VPCF133FX) and its running really slow.
I just formated it, and its clean and virus/spyware free, but it still preforms really low.
All the drivers are insteald correcty and there are no troubles.

I dont really know much about hardware(duh) but I think the problem might be the processor..
So I downloaded the CPUID CPU Z application CPUID-CPU Z


It shows the Core speed is at ~930 Mhz which I assume is really low for an i7 processor (1,73ghz with turbo boost up to 2,93)

Im not really sure how to fix it or even see if turbo boost is enabled or disabled as sony laptops have very limited bios settings available.

Does anyone have any ideas or simular experience? any inputs could help me.


Thank you in advanced!!

It down clocks itself when it is not in use. It's called Speedstep. Open a program while watching that and you should see the frequency jump up.

I dont think its just that, as it dosent really change when I opet applications such as Photoshop.
Also Im not sure if it should be as low as 930 MHz.

Does any one know if changing the c3/c6 state support makes the processor run faster? (its the only setting in bios that I can change)

It may not require that much CPU power. I am almost sure that is what it is. Try opening A more intensive program or DL prime95 run cores at 100% and check speeds.

Just so you know i am Running a core i5 oc'd at this moment at 4.6ghz when not in use running at around 950's

I tryed withprime95 and heavyload , the cpu usage was at 100% but the cloak core speed stayed the same(~930Mhz).. now I'm really getting worried..
Could there be an hardware error with my processor?

Do you have "Fast start" or Hibernate enabled?

Fast start is a windows 8 thing and has been known to cause these problems.

Control Panel > Power Options > Chose What the Power Button Does > at the top, click "Change settings that are currently unavailable", the under Shutdown Settings, uncheck "Turn on fast startup".

Also try disabling Hibernate mode as well. Reboot see if that changes anything.

I'm using windows 7 ultimate with SP1.

wow, Thanak you,I did disable Hibernate mode and it does seem to speed things up a bit, but the core speed stays at 930Mh (when runing torture tests)

Really weird.. will try runing a game now and see what happens.

Also try monitoring with another program like Coretemp.
