Core i7 4770 Intel Turbo Boost Technology help.

[ibrahimasghar]

Hello people, my PC's processor is Core i7 4770 @ 3.4 GHz. I wanted some help on Intel Turbo Boost Technology. It's written on Intel's website that this processor reaches 3.9 GHz on Turbo mode.

Since my processor isn't the 'K', i went to BIOS and was looking for Turbo Boost, when i found the Intel Turbo Boost Technology, and below that there were separate settings for all cores. Intel Turbo Boost Technology was set to 'Auto', so i proceeded to click the drop down menu and changed it to 'Enabled', i didn't see the cores, because all of the cores were set to 'Auto'. I just 'Enabled' the Turbo Boost Technology, then click save & exit.

My question is, does my processor have a Turbo Boost now?. Thanks.

Auto normally means enabled. Kind of strange that your mobo even has an auto and enabled option, since on my Asus mobo it's either On or Off.

The default setting is AUTO, which in every case I have ever seen meant that it was on by default.

Understand that Turbo mode at 3.9 Ghz is when only 1 core is running in Turbo mode. For each additional core that enters Turbo mode, the highest speed any core can reach in Turbo mode drops 100 Mhz. Even if there remains work to be done, but a certain temperature is reached, turbo mode ends, and the CPU goes back to its listed speed, 3.4 Ghz in this case.

So the short answer is that it probably has had it all along. And changing the setting from AUTO to ENABLED probably did not change anything.

Now, computers being computers, and having been programmed by HUMANS, who we all know never make mistakes, especially not when programming system hardware <snicker>, I would highly recommend that you monitor the temps of your CPU for awhile if you are going to leave those set to ENABLED. Despite the fact that nothing SHOULD have changed, it might do something we can't even imagine. So be cautious.

I was actually thinking the same thing that why is there an 'Enabled' option when it's already set to 'Auto'. My mobo is Gigabyte G1 Sniper Z87, the BIOS is pretty detailed. But not user-friendly.

Thanks MarkW for educating me on this issue, i think i will revert it back to 'Auto' since that also means enabled. I thought that maybe when 'Enabled' is selected, more power will be directed towards the processor automatically. But i've limited knowledge in this so i guess reverting back to 'Auto' is okay. Better safe than sorry.

I would agree.

I would agree.

Thanks man, i've reverted it back to 'Auto'
