Hello, I have a Samsung ultrabook with core i5-3337U@1.8 Mhz processor.
Until yesterday the turbo boost monitor shown that the processor use additional processor power when needed reaching up to 2.6 Mhz.
Yesterday I update the Wifi, Widi and HD4000 graphics drivers to the latest versions.
Now when I start my system I get the following message:
now the turbo boost feature don't work and the processor never go beyond 1.8 Mhz
How I can enable the turbo boost?
Thanks for your help.

Hi JaimeCruz,
The Turbo Boost Feature can be disabled or enabled at bios level depending on the options that the manufacturer has developed.
I recommend you accessing the bios and resetting the settings defaults since the drivers you install should not affect at all this processor feature.

Hi Kevin,
thanks for your answer. At bios level I can only put on or off the processor ECO mode. Tried On and OFF and not change in the turbo boost. Another problem I found was that I can't change the screen brightness.
Finally the only solution I found is to make a system restore to a point before loading the new Intel drivers.
Now everything works OK.
I think that Samsung drivers have a "some" difference from the original Intel drivers.
Thanks anyway and good bye.
Jaime

Hi JaimeCruz,
I also have this problem on same ultrabook with yours (samsung ultrabook series 5 with core i5-3337U@1.8 Mhz processor).
I did factory reset few days ago and then updated all samsung software (because of hdd replacement).
Then, I notice that cpu clock on task manager stay in 1,8GHz and a notification about Virtualization (if I am not mistaken) is not supported in this processor while installing a software. I checked Hyper-V in Windows Features dialog box.
- What is name of old samsung application to change cpu clock / eco mode? I still have old samsung' systemsoftware backup. I hope by reinstall it will solve the problem.
- I don't think to do reset to factory setting anymore. I did twice last month TT__TT.
Thank you.

Hi,
After I reset my samsung ultrabook to factory setting, I did a little troubleshoot and then found the answer.
It is because of << Hyper-V checked (on) >>!!!
In this ultrabook (processor i-5 3337U), if you check Hyper-V feature in Windows Add Features dialog
-- Windows fail to read processor Turbo Boost (I guess). Windows Task Manager will show processor speed is 1,80 GHz all time.
-- This failure will affect to processor fan. The fan will never change it speed to higher speed and make my ultrabook temperature increase.
Next, I tried to check (activate) Hyper-V on my brother Microsoft Surface Pro with i-5 4000U processor. Everything run normal.
So, I can guess that there must be something (bug, error or...) in this (my ultrabook) i-5 3337U processor, don't know it is at processor level or windows level.
need replacement if I want to activate Hyper-V. TT___TT
