post #2311 of 2500
F7 has been working for me but stock across the board. I've yet to oc anything again. Might borrow my nephew's haswell setup and test his cpu on my board and my cpu on his to see what is causing all the crashing (might be ram as its now @ default non xmp).

Has anyone had problems with the CPU_OPT fan header on the Gaming 7 or similar. Maybe I just don't know how it works but I can't seem to get it to function but fans attached seem to do a few rotations when I power the PC on or off which leads me to believe it might not be a fault.
post #2313 of 2500
thanks

but is only when xmp is activated.

anyway, i have 4 modules
tomorrow i will test 2 by 2 to see what happen

The fans on that header must be working at system start.!
how many fans you have connect there?

It may make sense for you, but for me i'm still wandering why memory frequency impact CPU temperature cause the base clock stay at 100 mhz in both case didn't it ?

I don't know why this is happening with your DRAM kit but, please, get in the following very useful habit from this very beginning: get a good monitoring tool, like HWiNFO64 which is considered the best or any other you like to use, and start...speaking with screenshots! Post screenshots showing all these that you write. Posting a screenshot from HWiNFO64 where all the values will be shown, or at least all the temperature and voltage values will be shown, will give an immediate and clear "snapshot" of what exactly is going on in your system. Then the people will be able to help you much more efficiently.

I recently updated my GA-Z97X-UD3H-BK (rev. 1.0) bios from f6 to f8, but now when activate x.m.p. profile the uncore ratio don´t drop anymore
so downgrade to F7 and the same, don´t drop, only when xmp is activated
i can´t back to f6
My questions:
this issue can be a big problem on short or long time?
How can affect the performance?
When the Z97 BIOS were "upgraded" for Broadwell cpu's, for whatever reason Gigabyte didn't see fit to let the uncore drop at idle on some BIOS. Will it hurt anything? No.
If it really bothers you look for the FPT tool for Z97 and use it to flash back to an earlier version.

Ok I'll start to take Screenshot to picture my case.

So I get back in Bios,, hit "Load Optimized Deafault", save&exit.

I run a cinebench under this defaul bios.
One things to notice is that I'm undervolted and limit to 4.2 Ghz for all cores, witch in default gigabyte bios is the lowest turbo frequency of the #4 core (core 1 & 2 at 4.4, core 3 at 4.3 and core 4 at 4.2).

Here is the screenshot :
Idle :


Under load :


Now when I activate X.M.P. Profile 1 for my memory :


, I go automatically go up to 4.4Ghz under load at 1.25V :

Idle with XMP :


Under load with XMP :


And now to show a more stressfull application, I use x264 stability test 16T (the version modified by user on this forum) with XMP :

Two quick notifications:

1) Get HWiNFO64 and do not use this monitoring tool you are using. What you use now says your VCore is...1.6something! Get HWiNFO64, the latest beta, and monitor your system with it correctly.

2) At Optimized Defaults you are not..."undervolted" nor limited, when running at x42. It is the Intel i7-4790K which at optimized defaults maxes up to 4.2 GHz, under full load. It is absolutely normal.

Get the appropriate monitoring tool, and then post again. It is not appropriate to discuss voltages / temperatures when they are not monitored correctly.

Thank you.

Thank you.

Thanks I'll correct this right away.

You find me surprise about your 2nd point. In my mind i thought intel turbo boost of an i7 4790K was 4.4Ghz not 4.2 Ghz ...

Anyway here are the new sreenshoot using HWiNFO64 :

A) Optimised default BIOS :
1) IDLE


2) Cinebench


3) x264 16T



B) Optimised default BIOS with XMP profile for RAM :
1) IDLE


2) Cinebench


3) x264 16T



See how i get about +10°C on x264 16T when i enable my XMP profile ! ?

Okay, thank you for getting the appropriate monitoring tool, good to yourself you did because this is the tool you should trust to monitor your values.

Quick notes, I'm in a hurry right now:

1) Scroll down a bit in HWiNFO64 and you will see your VCore(s) voltage values. This is what should interest you, this is what you should monitor. If you are interested in HWiNFO64 - and you should be - read this post of mine.

2) Intel, at optimized defaults, applies a per-core o/c of x44 x44 x43 x42, if I recall correctly. You can check it out yourself in your BIOS. This is why at full load (= on all 4 cores) it locks at x42.


You can expand HWiNFO64 to three tables but pressing the arrows at the bottom left corner. Try it out.

Finally, your Core temperatures are too high for this VCore. What is your ambient temperature? Consider re-seating your CPU cooler and eventually replacing your TIM, after cleaning the old one thoroughly: isopropyl alcohol + coffee filters. What TIM do you use and when was the tube opened?

Are all your system's fans running at full speed when you stress test? Even if they are, still too hot you run!...

PS: Update, please, your system by placing all your components and your chassis fans.
