I stress my CPU with Prime95 and yet the clocks speed doesn't change.

[Tulik]

Following my previous thread.
A new i7-4790K w/ H100i.
For some reason my clocks speed are at 3.40GHz. after a few searches, I figured that this is simply the idle clock or w/e (as edited in the original thread, about SpeedStep), but I now stressed my CPU with Prime95, as shown:

and the clocks speed remain at 3.40GHz, STILL!

What am I missing here? What have I done wrong? It really troubles me... As you can see, the temps are just fine, so why doesn't the CPU boost up to 4.5GHz (Turbo mode), or even just 4.00, as it is supposed to? :\

Thanks guys..

Hi

What program is displaying clock speed ?

I assumed boost speeds occur under situation when only few cores are in use

If prime95 or similar loads all 4 cores you won't won't get a speed boost
This is to limit the power consumption and heat generation of CPU to acceptable limits

It's very likely that you have missed a setting in the BIOS. I didn't see a motherboard listed, but if you have the ratio manually set or something, it won't go to the turbo speed.

Your motherboard could be the culprit. You shouldn't have rushed replacing your i5 with an i7. This motherboard has a 4 phase power design, the VRM could be overheating a lot and throttling your CPU frequency. It also could be that the motherboard has faulty VRM.

As shows above... the softwares displaying the clock speed are CPU-Z and HWMonitor..? X:
Thanks

Sorry, I mentioned the Mobo in the original thread:

Before upgrading, I made sure here that my MoBo (GA-Z87-HD3) indeed supports the CPU. My BIOS version is F7

I took a photo of the BIOS;

Sorry for the poor quality, but I think it's still readable.
Any clue what those 'on/off' buttons on the right are?
And as you can see - it is set to 34 (3.40Ghz) for some reason, but when you open up the menu, you don't have an option for 'auto'... What do I do? Is that the problem?

Thanks!

first of all I'd like you to read my comment above (about the MoBo) - as you can see, it does support the i7, also - the screenshot suggests it caps at 34 for some reason.
I did not rush anything. I even made a thread about it here before upgrading, just to make sure.
Thanks =[

Change CPU base clock to whatever your target overclock is.

What if I don't wish to OC it? Atleast not yet. I'd like to make sure it runs at 4GHz and boosts to 4.5GHz when needed (by Turbo) =[
What do I do then?

These should be the default motherboard settings anyway. Some z87 chipset motherboards need a new bios to support Haswell refresh processors like yours. If you know how to, flash the most recent version of bios for your motherboard if you don't already have it.

I think you are onto something!
As I mentioned several times, when making sure my MoBo and BIOS versions support the new CPU, I checked here, www.gigabyte.com/support-downloads/cpu-support-popup.aspx?pid=4489 (and then made sure my BIOS version is indeed F7), so I didn't think I should flash my BIOS, but I now go to the BIOS page, and I see this:

So yeah, I think F8 should be it!
I have a problem, though.
These are the files that I have extracted from the .RAR:

.
When I try to run Efiflash, I get the following message:

And when attempting to run autoexec, I get this one:

Yet, as you can see from the website screenshot above, there is only one version that can be downloaded.
I am kind of confused. What do I do now?

Thanks a lot!

EDIT:
After a Google search, to my understanding I'll need to use a USB drive for that. Is there a way around that? Not sure I have another USB to spare

First of all, you should never flash your bios from inside Windows, that can damage your hardware and render your motherboard useless. The right way to flash your bios is from a flash drive from dos. You should put the bios files on a bootable flash stick and boot from it, and upgrade your bios. To make a bootable flash drive you will need to use a program like Rufus.

 

[Tulik]

Gotcha, thanks again.
I used a bootable USB for windows as well, so I guess I'll just format it and use it now, cause this is my only USB available.
Anyhow, I chose FAT32 (it was set to NFTS by default), but what do I pick here?

Or should I just leave it at FreeDOS? Not sure what the differences are.
Thanks!

FAT 32, Either MS-Dos or Free dos will do. Here is a guide on how to upgrade Bios for Gigabyte motherboards. http://www.gigabyte.com/webpage/20/images/flashbios_dos.pdf

Why not do it directly from the BIOS utility? Copy the BIOS file to a USB stick and flash it directly from the BIOS.

I KNEW I wasn't just being paranoid! I knew it would solve it!

Thanks a LOT dude! I really appreciate all of your help.
Look at this beauty now:

The clock speed changes automatically. That's what I'm talking about!

Again - thanks a lot for your help!
I'll pick your BIOS flash remark as the solution.

EDIT:
Well apparently it wasn't the cause of my low FPS (seeing how my FPS is still lower), but I am still happy to have solve this issue. If i wouldn't have experienced the FPS issue I wouldn't have been able to stop the BIOS update thing at all and stick to 3.40GHz for no reason.
