Intel turbo boost question

Quadacon · Aug 10, 2014

Hi, yesterday I purchased new parts for a build, i assembled it and it is all running smoothly except for a slight issue with the CPU, it is an i5 4590 with stock speeds of 3.3Ghz and turbo boost speed of "3.7Ghz".
first of all, under the system tab in control panel where you can see your systems specs, in the processor section, it shows the CPU name, the stock speed, followed by the turbo speed, both numbers are 3.3Ghz, this would suggest to me that turbo boost isn't on or working, i went in the BIOS of my Gigabyte H97-D3H Motherboard and changed "intel Turbo boost technology" from "auto" to "enabled". the problem still remained. I ran prime 95 and the max speed the CPU gets to is 3.5Ghz, this proved to me that it is working, but not properly.
btw the CPU ran at about 60 degrees celcius when maxed out with prime 95 and about 30 degrees while idling, I am using a hydro H75 cooler.

thanks

The system tab in the control panel does not show the actual clock speed the CPU is running at.

Try CPU-Z, it will dynamically show CPU clocks.

CPU-Z shows 3.5Ghz (when maxed out) as i mentioned, it should be 3.7Ghz

since turbo boost is dynamic overclocking it would not go the the full 3.7ghz if it would be to hot. Make sure the temps you have are right. Try HWmonitor. If it is 60 then thats pretty cool and turbo boost should go to the full 3.7ghz.

CPU; 100%
Temp; 56 degrees celcius
Speed; wont budge past 3499.18Mhz

56 is really cool.

What mobo do you have

ruecklm14 :

Its a Gigabyte H97-D3H

Quadacon :

Make sure you have the latest bios drivers. your mobo supports turbo boost so its not your mobo.

I am on F3, there is F4 and F5 Available, however it just says, increases SSD performance and Improve Intel K-sku CPU performance
I will update anyway, do i get F4 and then F5 or can i skip straight to F5

It would be good to update it just to make sure its not a bios glitch. Its best to try this before you try anything like reseating the cpu and things that will take longer. If you dont want to do this the difference between 3.5 and 3.7 is pretty minimal. What are you doing with your pc?

Music and some photo editing and some games, nothing crazy.
When I update the Bios, do I get F4 first and then F5 or can I get F5 and skip F4? (I have F3)

you can just get F5. You probably wont see a difference of 3.5 and 3.7 in the things your doing. The noticeable difference is if you oc above 4ghz but your cpu wont allow that.

Ok thanks, I updated the Bios, Bios shows the CPU running at almost 3.7, Im thinking its a windows problem

yeah it could be. I have a i5 3570 turbo boost at 3.8ghz and cpu-z says its running at 4ghz all the time so... I think this is fairly common.

Ok, thanks, one last question before I choose a best answer, do you think my CPU is running as its supposed to? even though windows shows it a bit diffrent?

yeah, I'd trust what your bios say more than windows. Glad I could help

3.5 GHz is the top boost frequency with all cores at full load. 3.7 GHz is only when a single core is active.
